Microchip’s new GestIC® technology enables mobilefriendly 3D gesture interfaces Microchip announces its patented GestIC® technology, which enables the next dimension in intuitive, gesture-based, non-contact user interfaces for a broad range of end products. The MGC3130 is the world’s first electrical-field (E-field)-based, configurable 3D gesture controller, offering low-power, precise, fast and robust hand position tracking with freespace gesture recognition. With power consumption as low as 150 microwatts in its active sensing state, the MGC3130 enables always-on 3D gesture recognition, even for batterypowered products where power budgets are extremely tight. The MGC3130’s low-power design and variety of configurable power modes provide the lowest power consump-
tion of any 3D sensing technology, up to 90% lower than camera-based gesture systems. GestIC technology achieves the exceptionally high gesture-recognition rates required by today’s consumer products through its onchip library, called the Colibri Suite, of intuitive and natural human gestures. The Colibri Suite combines a stochastic Hidden Markov model and x/y/z hand position vectors to provide designers with a reliable set of recognised 3D hand and finger gestures that can be easily employed in their products. Examples include Wake-Up on Approach, Position Tracking, Flick Gestures, Circle Gestures and Symbol Gestures to perform functions such as
on/off, open application, point, click, zoom, scroll, free-space mouse-over and many others. Designers can use this library to get to market quickly and reduce development risks by simply matching their system commands to Microchip’s extensive set of predetermined and proven gestures. Additionally, the chip provides developers the flexibility to use pre-filtered electrode signals for additional functionality in their applications. MICROCHIP TECHNOLOGY www.microchip.com/get/S238

The Path into the Post-PC Era The term “post-PC” is an official Apple corporate propaganda phrase, coined by Steve Jobs and promoted most of all by hardcore Apple loyalists ever since. In the near future, the concept of a personal computer may be radically different than it is today. Soon a phone could be smart enough to not just be a computer but it could be my computer. It will be a world where the only computer you will ever need, is a mobile one. Call it a phone, call it a tablet, or just call it a computer. The next generation of computers is poised to enable truly personal computing experiences. These devices will be tuned to the specific needs of its owner with an unthinkable amount of computing resources at its disposal. Computational resources will be harnessed locally through powerful 48 core CPUs combined with a near limitless supply of remotely accessible cloud computing capacity. Powerful multi-core mobile PCs play a central role in both our personal and professional computing lives. The one mobile compute device of the future will be in the hand and will automatically and wireless connects to a 30-inch display when the owner walks into the office. He has a touch, a keyboard, a mouse and voice to interact with it. It changes the whole concept of what it is and what it can do. In 10 years, the devices we carry will be continually using any information available to them to make better decisions. A continuous stream of location, identity, addriven information and presence status will all continually be calculating to help us do the stuff we do better and faster. To enable all these, 48-core chips for small mobile devices could hit the market “much sooner” than the researchers’ 10-year prediction. The industry is working on finding new ways to use and manage many cores in mobile devices. With many cores, someone could, for instance, be encrypting an email while also working on other power-intensive apps at the same time. Industry pundits have faith that by the time this complex hardware is ready, the software will be, too. These days, 5 to 10 years is somewhat of an eternity in technology time. If we are going to have this technology in five to 10 years, the smart phone will not have just one camera. It would have two to three cameras that are always on. It could build a three-dimensional map of what it’s looking at and do object recognition. Users could finally do things that take way too much processing power today. n (inspired and adapted from Forbes) Radu Andrei www.epd-ee.eu | November, 2012 | EP&Dee

INTERVIEW INDUSTRY NEWS
Interview with Mr. Tim Tatton, MD at Invotec Group Ltd. The company’s sale output figures reached a record- high in July this year, reaching over 2.7 million Euros, what do you think this means for Invotec Group’s future? We have demonstrated in a tough market place that we can continue to grow our market share & gain new customers. We have also demonstrated that our facilities can convert these opportunities into customer deliveries with ever increasing demands. Invotec Group Ltd appointed a new MD, Tim Tatton in recently this year. What does Mr Tatton see as his main goal for Invotec Group Ltd and what changes will Mr Tatton be implementing in his new role? Our primary goal is to continue to deliver the technology, quality & service that our customers demand. From that perspective nothing changes. What we aim to do differently, is invest even more in our facilities & especially our people to make Invotec’s position even stronger moving forward. We are embarking on a much more focussed approach to recruitment, training & development & we are increasing capital investment levels also. Invotec Group has recently acquired a shareholding in additive electronics and integration specialists, Printed Electronics Ltd (PEL). What does Invotec Group hope to gain from this partnership and how will this affect the company? PE is a technology which is very much in its infancy. We see possibilities for putting electronics in applications where they don’t currently exist. Our interest would be in niche applications, in much the same way as our current PCB portfolio, we are not necessarily interested in high volume consumer packaging for example. To this effect, we already have some Invotec customers who are interested in this technology through projects with PEL. The effect on Invotec in the short term will be relatively small until the technology develops further beyond the proof of concept stage. Invotec Group has announced the development of its Student/Graduate Apprentice programme. Why has Invotec decided to make this commitment to younger generations of Engineers and how will this benefit the company?

EP&Dee | November, 2012 | www.epd-ee.eu
We are based in the Midlands which has a thriving automotive & aerospace sector with some large players in close proximity. It is tough for SMEs such as Invotec to recruit experienced or graduate engineers when we have large corporations literally employing scores if not hundreds of graduate engineers each year. For this reason we decided to take talent from local schools/colleges & develop them ourselves, with education & practical training tailored to our needs. Why has Invotec Group decided to exhibit at Electronica this year and what does the company hope to achieve whilst they are at the event? We have chosen to exhibit as we plan to be more European focussed. We already have significant exports to Europe, but our aim is to grow this proportion of our sales. This applies in the military & civil aviation sectors & especially the space sector. This exhibition reaffirms our commitment to the European Market place.
Invotec Group won 4 customer awards this year, how does the company plan to build on this success and further strengthen its relationship with its customers? We are committed to the SC21 process (Supply Chains 21st Century) which is driven by the major Aerospace OEMs. This process encompasses business & manufacturing excellence, underpinned by Lean Manufacturing & continuous improvement. Ultimately this delivers consistent cost, quality & delivery for our business and our customers. Over time we expect to continue this process & continue our improvement.
We are confident this will push us towards the top performers to our customers, not just within PCB suppliers but across all categories. Invotec Group was recent bought by Rubicon partners, how has this changed the company? Invotec has a good reputation for technology & quality in a very demanding sector. However, we are seen as quite conservative given the talent & capabilities we have. With a larger, more financially powerful backer, we are open to grow more aggressively both organically and potentially through acquisition of companies with a similar profile in different territories. Our new shareholders wish to leverage our technology, quality & strong financial performance on a larger scale. Will you be announcing any company news at the show? We will be announcing further news ahead of the show regarding significant new capital investments & also news of a further customer
award. We can then share this news with our visitor at the show. What do you see as the main current challenges in your sector? As with most sectors, general economic uncertainty is always a concern. Clearly defence spending is under threat, but electronics is playing an increasing role in defence so this isn’t necessarily all bad news. Visibility is certainly shorter than it historically used to be in this sector. We feel that our strategy will equip us well for the challenges that lie ahead. n

Digital playback: Cutting cost not audio quality by Jayanth Madapura Senior Applications Engineer High-Performance Microcontroller Division Microchip Technology Inc.
Cutting cost without cutting audio playback quality is a challenge faced by designers of most audio docking stations and other digital audio devices and accessories. But it is a challenge that can be overcome by using the processing power of a 32-bit MCU or 16-bit Digital Signal Controller (DSC) for sample-rate conversion, and a low-cost, high-quality DAC to tune the sample rate to minimise USB clock differences. This combination can help to cut costs whilst maintaining audio quality. Digital audio systems consist of a docking station and an audio device: the serial stereo audio data, streamed from the digital audio source via the dock’s USB interface, is captured and routed to a Digital-to-Analogue Converter (DAC) at a set sample rate. Figure 1 details the components: a serial data-input channel; deserialiser;

sample-rate adjustment circuit; DAC with output filtering; and audio power-output stage. Not all of digital audio sources use the same sampling rate, so the dock typically adapts the sampling frequency to the source, or converts the sampled data stream into a common data rate. The first challenge, therefore, is to per-
form the sample-rate conversion at the lowest cost without degrading audio quality. Typically, designers have used a dedicated sample-rate conversion circuit or a high-end audio DAC that incorporates complex phaselocked loops to ensure flexible sample rates for stable communication of the sampled audio data. However, whilst USB provides a convenient interface for transferring audio data, USB jitter produces a subtle loss of audio quality meaning that, in addition to converting sample rates, a sample-rate converter must also mitigate USB jitter. Understanding digital audio Analogue audio is converted into digital format, by sampling the analogue signal at a frequency which is at least twice the highest-frequency component in the analogue signal, or the Nyquist rate. An audio signal of 0 to 20kHz can, therefore, be sampled at a data rate of 44.1kHz, which is the appropriate Nyquist rate, so that the signal can be reconstructed without aliasing when converted back to the analogue

EMBEDDED DESIGN
domain. In addition to the sampling rate, designers have to decide whether the resolution of the conversion will be a 16-bit word or a 24-bit word. For compact disc (CD) audio files, the standard is 16-bit resolution with a 44.1kHz sample rate. However, there are higher-performance options for audiophiles, such as encoding the data at 24-bit resolution and increasing the sampling rate to 96kHz. For audio professionals, the audio files are encoded with a resolution of 24 bits per sample, which provides sufficient headroom when the audio is mixed and manipulated by the studios in preparation for creating the master. The choice of resolution allows the designer to trade-off sound quality against the file size even when compression is applied. Larger resolutions provide higher audio quality, but mean that the storage file size will be larger. For example, a 4-minute stereo audio file with a 44.1kHz sample rate and 16-bit resolution, requires a file size of about 42 Mbytes. However, if the resolution is reduced, less storage would be required. With a resolution of 12 bits, the audio file size would drop to around 30 Mbytes, but at the expense of relatively lower audio quality. The USB interface is capable of streaming high-quality audio and is popular among many audio users. With its universal ease-of-use, USB audio can transfer high-resolution and high-sample-rate audio with negligible jitter, when packaged with a flexible audio interface. Isochronous data transfer is used to stream audio data to and from a source at a constant rate in real time. Stereo audio data packets, with size governed by the sample rate of the audio stream, are transferred as part of USB frames every 1 ms on the USB full-speed link. USB audio also provides controls for features such as volume, tone, gain control, and equalisers, among many control and processing units. Quality versus cost The difference between bit rates and sample rates means that the hardware in the playback system or dock must be able to handle the differing-rate data streams. To do this, the designer has three options: the system must either use a more complex, and therefore more expensive, DAC to phase-lock to each sample rate and adjust itself to each playback option; or use an external sample-rate converter IC with the low-cost DAC; or convert all the streams into a standard sample rate and bit rate using an algorithm running on a microcontroller (MCU) that a simple low-cost DAC can handle. Figure 2 shows these options. These solutions are used by many playback system designers. In one scenario, a designer purchases an off-the-shelf SRC and DAC solution to do the sample-rate conversion and DAC playback. An alternative solution combines an SRC IC with a low-cost DAC. This solution is optimised for a high signal-to-noise
ratio, low power, and minimal jitter, however, the SRC chip adds to the total system cost. Another alternative is to use a more expensive audio DAC that contains the phase-lock circuits and switched capacitor filters to handle the fractional clocks so that they can lock onto each of the different sample-rate data streams. Although these approaches are all viable, they all either require an extra chip, or a higher-cost DAC. However, by using a relatively powerful 32-bit microcontroller or 16-bit Digital Signal Controller (Digital Signal Controller) which can deliver performance levels of 40 to 80 MIPS, designers can eliminate the need for an external rate-conversion chip. This is because the 32-bit MCU or 16-bit DSC is able to perform sample-rate conversion on-chip, without compromising audio quality. Since the SRC output sample rate is constant, a low-cost, high-quality 24-bit audio DAC can be used.
the SRC algorithm to convert real-time audio data sampled at 44.1kHz or 32kHz to a sampling rate of 48kHz. To accommodate the USB link frame rate, the size of the input audio data frame is an interval of 1 ms, with 64 stereo samples for 32kHz input, or 88 or 90 stereo samples for 44.1kHz input. The output consists of 96 stereo samples per 1ms. In a typical SRC block, the incoming audio data passes through an up-sampler or an interpolation stage. The signal then passes through an anti-aliasing low-pass filter, followed by a downsampler or decimation stage. A simplified sample-rate conversion circuit is shown in Figure 4. Assuming conversion from a 32kHz to a 48kHz sample rate where the conversion factor is 3:2, the input is up-sampled by a factor of 3, followed by a FIR filter with a steep roll-off to smooth the signal. A gain factor of 3 is applied to the smoothed signal to compensate
Figure 2: Playback options: cost versus performance trade-offs. Many systems use an 8- or 16-bit embedded MCU to handle all the housekeeping functions, such as communicating over the USB interface; controlling the display; button control; volume control; and interface management. Microchip’s high performance PIC32 MCUs and dsPIC33E DSCs can be used to perform SRC on-chip and can also to perform all of the system interface and housekeeping functions. For example, by using a high-performance MCU, the sample-rate conversion can be performed whilst maintaining audio quality, since the intermediate calculations are 32 bits. Any deterioration due to truncation of the calculated values is therefore avoided. The dsPIC33E DSCs and PIC32 MCUs, shown in Figure 3, provide a choice of on-chip resources, such as non-volatile Flash memory, static RAM, and peripherals, to enable designers to use the most suitable variant for their system. Some devices also offer low power consumption for use in power conscious applications. Using an MCU for sample-rate conversion Sample-rate conversion can be achieved, for most common audio sampling rates, by using
for the loss caused by inserting the zeros. The resulting intermediate signal is down-sampled by a factor of 2 to obtain an output audio signal at a sampling rate of 48kHz. Since down-sampling creates redundancy in the filtering of the sample that is decimated, the filtering of this sample can be skipped. This simplified form of the polyphase filtering technique improves the speed of the SRC. For a 44.1kHz to 48kHz sample-rate conversion, where the conversion factor is 160:147, the processing block is as follows: The input is up-sampled by a factor of 2 by inserting a zero after every input sample and applying a FIR filter to smooth the signal. A gain factor of 2 is applied to the smoothed signal to compensate for the loss caused by inserting the zeros. Polynomial interpolation is used to reduce every sequence of 147 samples at 88.2kHz, to 80 samples at 48kHz. This ensures that the sampling rate of the output audio data is 48kHz. Polyphase filtering is also employed in this mode to reduce redundancy. The overall processing load is dominated by the filter, with a trade-off between filter length and the quality of the outputs. www.epd-ee.eu | November, 2012 | EP&Dee

audio data under-run or over-run is to use a good Asynchronous Sample Rate Converter (ASRC), where the input sample rate is estimated with jitter attenuation, and the internal filters are dynamically tuned for a new sample rate.
Figure 3: The PIC32 MCUs with a MIPS processor core handle sample-rate conversion and housekeeping functions.
Figure 4: Simplified sample-rate conversion circuit. Mitigating USB clock mismatch A tolerance budget and a limit on the USB clock frequency are included in the USB specifications to achieve immunity to radio interference. The USB clock with the allowed tolerance budget results in reduced audio quality if there is USB clock mismatch. The real-time streaming audio samples must arrive at precise and regular time intervals so that the DAC can convert the digital samples to an analogue signal with the expected constant rate at which it is configured. The DAC clock that expects and receives the audio samples at a particular sample rate must not miss a single sample. For the listener, a missing sample becomes a slight click, since the DAC fails to generate an accurate representation of the streamed audio signal. On a MCU or microprocessor with embedded USB module, the USB clock is sourced from an independent clock such as an on-chip PLL with an external crystal oscillator of a specific value. Since the clock is not sourced from the USB interface, the mismatch in clocks introduces buffer over-run or under-run, which causes clicks, as shown in Figure 5. An easy answer to the problem of
10
EP&Dee | November, 2012 | www.epd-ee.eu
The trade-off here is that a good ASRC is very expensive and the system will still need a DAC for analogue conversion.
The feedback mechanism monitors the buffer level and ensures that it stays within an acceptable range, while achieving at least the same, if not better, quality achieved by an expensive ASRC. One option is to use the DAC with a PLL that allows fractional tuning of the sample rate based upon buffer-level feedback. This solution is relatively less expensive than an ASRC chip. The PIC32 MCUs and dsPIC33E DSCs have a flexible independent system clock PLL, and a USB clock PLL with independent clock sources. The USB PLL can be clocked with an external crystal to achieve the exact 48 MHz USB clock required. The system clock can be sourced from the Fast RC (FRC) clock. On the PIC32 and dsPIC33E devices, the FRC clock is tunable and can be configured to tune the DAC clocks. This prevents buffer under-run and over-run while maintaining an acceptable DAC sample rate with a swing range of 0.2%. Of the three possible solutions, this is the lowest-cost solution whilst still achieving low power. Summary The trade-off between cost and audio quality in docks or device accessories can be mitigated by adapting to the sample rate of the source or converting the sampled data stream into a common data rate. USB clock mismatch must also be addressed by tuning the sample rate to prevent buffer over-run and under-run. By using a MCU for sample-rate conversion and sample-rate tuning, the external chip count can be reduced to minimise system cost and maintain high audio playback quality. A 32-bit MCU or 16-bit DSC, such as the PIC32 and dsPIC33E, can perform sample-rate conversion as well as interfacing to a low-cost, high-quality DAC which can tune the sample rate to address the problem of USB clock mismatches. These MCUs and DSCs provide a range on on-chip features which provides the flexibility to manage the trade-offs which are

Computer-on-Modules' concepts to suit ARM SOC by Gerhard Szczuka Product Manager for Computer-on-Modules Kontron Europe
Up to now, designs of ARM-based applications were primarily marked by their application-specific characteristics and - more often than not - their full-custom designs. Scalable, standardized building blocks especially for ARM- and SOC-based designs can dramatically reduce the development expenditure and speed up time-to-market of embedded applications even with production batches of >200. A very effective platform for this is ULP-COM, a Computer-on-Module concept which embraces all the important aspects of efficient design-in for ARM-based applications. For a long number of years, ARM technology has been the established technology for dedicated systems, whether in set-top boxes, receivers, switches or as simpler smart interfaces for higher-quality white goods. New applications, like smartphones and tablets, have emerged which bring ARM technology closer to the application areas of ×86 architecture. And with this, ARM technology – even just because of its enormous sales impact in the consumer market - has become very interesting for embedded designs. This mainstream success makes it possible to offer a powerful embedded roadmap. Often though, full-custom designs play an important role, as many of these solutions are sold in particularly large numbers. Scalable building blocks are required What is however the case with embedded applications with quantities that make full-custom designs non-economical? Here, developers and OEMs need a solution which delivers a balance between development time and costs on the one hand and average costs on the other. This is where scalable building blocks are an ideal solution, as OEMs can quickly and simply design them into their applications and

they offer maximum flexibility and design security. It is also ideal if OEMs can integrate the ARM processors into their applications via building blocks which have already been vali-
dated. By doing this, OEMs can save significantly on resources, which in turn can considerably reduce the Total Cost of Ownership of the whole application.
Current ARM processors are on the same performance level as Intel Atom processor technology while offering significantly lower power consumption.
EMBEDDED DESIGN
ARM-COMs on the advance Computer-on-Modules are such building blocks and the COM concept with additionally purchased and integrated components and application-specific carrierboard is gaining popularity. Figures from IMS Research confirm this trend. In 2011 39% of all COM shipments were ARM-based modules, the majority of which were full-custom designs. Up to 2016 it is expected that they will account for a massive 59% of the module market. The market's need for ARM-based COMs is therefore gigantic and will experience a further sharp increase. ARM-COMs will not however replace current ×86 designs but penetrate market segments in which ×86 technology to date – due to price, power and TDP restrictions - was not able to enter. Target applications are to be found predominantly in areas with graphical user interfaces featuring touch screen control, where upgrades from simple line displays to fullgraphic support with minimum power consumption are taking place or migration from ×86 platforms to ARM is required. Application scenarios are, for example, medical devices, handheld devices in harsh environments, solardriven outdoor devices, like ticketing machines for parking, electric pumps for e-cars or digital advertising at bus stops. Vehicle applications for fleet management or digital signage/infotainment in buses and trains and mobile testing equipment as well as kiosks, cash- and weighing systems are further examples. High performance low consumption What though makes ARM processors on COMs so interesting? Current ARM processors in dual- or quad-core configurations deliver a performance on the level of Intel Atom processors. On average, the power consumption during operation is under 2 watt. There are also many ARM-SoCs available for the extended temperature range. This means that, all in all, passive cooling solutions can be kept very simple and complete devices can be created which are compact and cost-efficient. The demands of ARM SoC in terms of power supply are much lower than the voltage processing needed for ×86 platforms, which further reduces development effort and costs. What's more, ARM processors boast a longterm availability of up to 15 years. Still no uniform COM standard ARM processors, however, 'come by' their high energy efficiency through their designs which are tailored to meet specific application scenarios. Quite different from ×86 technology, which connects application-specific peripherals and interfaces via generic data buses like PCI, PCI Express or USB, ARM processors integrate dedicated controllers and interfaces. This dedicated form of I/O of the different ARM SoCs has to date led to proprietary COM designs which usually were developed
on a specific ARM System-on-Chip. An additional issue is that ARM SoCs use different interfaces than ×86 technology does for similar tasks. An example are MIPI interfaces for small, inexpensive displays and cameras rather than DisplayPort or USB in the case of x86 designs. The SPI Serial Peripheral Interface instead of PCI or PCI Express is used in ARM designs much more frequently for connecting peripherals and data storage or extension modules are connected via SDIO and not frequently via SATA. So, all in all, COM concepts like Qseven or Core Express®, which were originally developed for ×86 processors are not ideal for ARM designs. If they have to remain within the specification, ARM variants can only have the smallest common denominator of interfaces implemented. That, however, limits the usability of such modules considerably, as the non-defined pins can be used by any manufacturer for different purposes. With that, one of the basic ideas of COM technology, different sources and reliable standard documentation, crumbles. To date there is no overall Computer-on-Module available which satis-
it possible for OEMs to reduce their development time for ARM-based applications by around nine months. The ULP-COM specification The new specification for Ultra Low Power COMs has been designed to suit the typical demands of new mobile and – more often than not – battery-driven applications. Mobile devices, like embedded tablets, have to be slimly built while still offering room for additional components or coming higher performance SoCs. Therefore, ULP-COM specifies right from the start two different module sizes: a short module with 82 mm × 50 mm and a full-size module measuring 82 mm × 80 mm. The module 'width' of 82 mm is defined by the connector and with that cannot be altered. The short module is suitable for compact handheld devices, which fit into a closed hand. Full-size modules offer enough space i.e. for future, higher performance SoCs designs which need more space for heat dissipation. The standard offers great flexibility right from the start and enough room for up- and coming developments.
ULP-COM specification defines two different module sizes: 'short' and 'full size'. fies the expectations of a COM specification which is as universal as possible. A new standard is required In order to be able to create such a multi-functional and long-term available COM standard – as has been successfully achieved in the ×86 with COM Express® - a new COM specification has to be created. A platform has to be developed which, based on its plug-in connector and the largest possible selection of usable ARM-specific interfaces, integrates several SoCs with different performance classes. Together with other embedded firms which are globally successful, Kontron has therefore developed a Computer-on-Module standard especially designed for ARM and SoCs which offers the industry an optimized pin-out and the highest level of design safety: ULP-COM. With this new specification Kontron has made
Compact, flat designs One of the most important issues for these new applications is the flat build of the modules. The connector between the module and the carrierboard has the greatest influence. It dictates the minimum thickness which is possible. ULP-COM modules rely on the MXM 3.0 plug-in connector. The plug is just 4.3 millimeters thick and thus allows for especially flat designs with a board to board distance of just 1.5mm. Applications with a total thickness of just under 9 mm are possible, this thickness is therefore only further influenced by the interfaces which the customers requires. The plug-in connector has proved reliable in dedicated graphic cards in notebooks and is available from several manufacturers. So it is not just an established but an inexpensive and above all long-term available solution. www.epd-ee.eu | November, 2012 | EP&Dee

HDMI. Further to this, the Kontron ULP-COMsAT30 supports camera connection via two dual-lane CSI camera ports.
The extremely thinly built MXM 3.0 connector (4.3 mm) allows for the development of compact handheld devices. Owing to the 314 pins a large number of dedicated I/Os in current and future SoC and ARM processors can be assigned. Numerous signaling lines On the electrical side, the connector offers a total of 314 pins. 33 are reserved for signaling lines for power supply and grounding, so effectively the ULP-COM offers 281 signaling lines. That means 50 more than, for example, the MXM 2.0 connector had, which amongst others is used on Qseven Computer-onModules. A high signal capacity is therefore an especially important issue, as the number of available signal pins is the basis for the most extensive and at the same time versatile pinout of the Computer-on-Modules. In this way, significantly more dedicated interfaces can be specified on the connector. A special feature of ULP-COM is the so-called Alternate Function Block (AFB). This is a set of 20 signaling lines which are reserved in the current specification for application- and manufacturer-specific usage. In future versions of the specification new standard functions can therefore be assigned to these reserved signaling lines. This ensures that the specification can flexibly incorporate future technical developments which today are not even on the cards, while still upholding full compatibility with existing designs. First modules available soon Already, Kontron is developing the first three Computer-on-Modules according to the new ULP-COM specification. The first module is the Kontron ULP-COM-sAT30. According to the ULP-COM specification it measures just 82 × 50 mm and integrates Nvidia's Cortex A9 processor design Tegra 3 Quadcore with 800 MHz. The module is destined for graphic-orientated applications such as digital signage or media players. To fit this bill, it offers superior high-end graphics with dedicated interfaces for two independent displays including hardware-accelerated HD video decoding for MPEG2 and HD video encoding as well as 2D and 3D acceleration. Flexible display connection is carried out via parallel LCD, LVDS 18 bit single channel and

The Kontron ULP-COM-sAT30 measures just 82 mm × 50 mm as defined in the ULP-COM specification and integrates Nvidia's Tegra 3 Quadcore processor with 800 MHz. The second new module is the highly scalable Kontron ULP-COM-sAMX6i with single, dual or quad core ARM® Cortex A9 technology. Based on Freescale’s i. MX6 Series processors, they cover an extremely wide performance range with a balanced processor and graphics performance. The Kontron ULP-COM-sAMX6i Computer-on-Modules exceed the traditional scale of longevity with their availability of at least ten years. Furthermore they support the extended temperature range from -40°C to +85°C bydesign. Thus this new module family is ideal for market sectors demanding highest ruggedness and long-term availability, such as for example transportation, medical and military based on open standards software. And a third ULP-COM module will be coming soon. It will be based on the Texas Instruments Sitara AM3874 with ARM® Cortex™-A8 microprocessor (MPU) and will provide a wide range of choices for integration onto industrial applications. Those modules offer peripherals for high bandwidth connectivity such as SATA, Dual CAN, PCI Express (PCIe) and a Gigabit Ethernet switch. Manufacturer-independent standard With all these technical advantages of the ULPCOM specification, the question of manufacturer-independent offerings of modules and services as well as the supervision of a manufacturer-independent panel arises. This is a major criterium to ensure that a standard actu-
ally becomes a standard. Kontron and Adlink rely on the newly founded manufacturer-independent Standardization Group for Embedded Technologies e.V (SGET). The SGET already has received the ULP-COM specification for ratification. The SGET work group plans to examine this specification at short notice and to approve it as an official SGET specification as soon as possible. With further embedded companies like ADLINK, Fortec and Greenbase more modules and carrierboards are being developed. Kontron already has a carrierboard available and a starter-kit in the pipeline which will become available in Q4. This allows customers to immediately start testing their embedded target platforms. Apart from these standard products, Kontron also offers extended complementary services for its platforms to speed up hard- and software integration. Software services In addition to obtaining the right hardware design, ARM requires substantial support on the software front. In order to pave the way for developers to enter this PC-like ARM technology as easily as possible, Kontron offers a wide range of software services. As ARM does not 'entertain' a BIOS as such, a bootloader is responsible for the start and the rest is taken care of by the operating system. If the application is, for example, to be run on the Android operating system to profit from a uniform Look & Feel on all platforms, certain initial requirements have to be fulfilled for each ARM processor. An ARM-optimized Linux kernel has to be equipped with the drivers for the required peripherals and prepared for operation via several patches. This is the basis on which the application framework of Android can be superimposed. This has been designed as such, in order to create a uniform Look & Feel on different devices. Android achieves this by integrating a Hardware Abstraction Layer (HAL) which presents the application framework with the interfaces to the hardware in the form of abstract modules. This requires manufacturers of ARM-based hardware however to guarantee that all components are available respectively as HAL modules for the software level and are furthermore anchored in the application framework. The effort therefore required in terms of operating system integration is considerable. Kontron has a solution which saves customers carrying out this very time-consuming work, ARM hardware platforms are provided not just as barebones but increasingly equipped directly with the fitting software support and – if so required – with the necessary licenses. n www.kontron.com
DISPLAY INDUSTRY NEWS
Dotmatrix displays are dead - long live the Dotmatrix display
ELECTRONIC ASSEMBLY – Displays designed to make things easy
Electronic Assembly developed its EA DIP203-4 LCD module for applications that require exceptional readability and will be shown it at the electronica 2012. The module features a high-contrast, alphanumeric LCD supertwist display for four rows of text at 20 characters per row. The dot-matrix display comes in three variants. Users can choose from black text on a yellow/green background, white text on a blue background, and black text on a white background. An automatic temperature compensation facility eliminates the need to adjust the contrast. The display is driven by a built-in controller of type SSD1803, which is 90% compatible with the popular HD44780 controller. The character set that ships with the display supports 240 letters, numbers, and symbols; users can also define eight characters of their own. The controller receives its control commands via a fast SPI interface.
Electronic Assembly markets a broad spectrum of top-quality industrial displays to customers in a number of industries ranging from process automation and machinery manufacturing to IT. A high level of vertical integration enables the company to keep a large portion of the value-add chain in house. Because Electronic Assembly offers all the familiar advantages of a mid-tier company, it has the flexibility to accommodate the wide-ranging needs of its customers. The product portfolio extends from simple seven-segment instrumentation displays to sophisticated color touchpanel displays for use at information booths or in complex system controllers. The wide-ranging portfolio includes for example products designed for extremely low power consumption as well as display modules for special markets and applications such as Cyrillic fonts. The company philosophy at Electronic Assembly is based on a simple vision. The senior management team of Stefan Eber and Carola Wittmann along with the entire staff is fully focused on “making things easy”. This vision is reflected in the design of the company’s products. The displays have a built-in controller which makes things a lot easier for design engi-
A 4 and 8-bit databus interface is also available for the display. The EA DIP203-4 is particularly easy to install, since no mechanical assembly is required. Simply insert the module into the circuit board and
solder! Power is supplied via a single line carrying 3.3 volts. The LED illumination requires a constant 150 mA for the green/yellow variant and a constant 45mA for the blue/white and black/white variants. The wide range of operating temperatures (from - 20°C to + 70°C) makes the display the ideal candidate for applications in many industrial environments. ELECTRONIC ASSEMBLY www.lcd-module.de
Brilliant and intelligent: 5.7" display for industrial and many other applications The EA eDIPTFT57-A intelligent display from Electronic Assembly is the ideal candidate for implementing interactive controls in mechanical engineering or industrial electronics applications. The screen, which measures 5.7" in the diagonal and has LED background illumination, offers a crisp, colorful resolution of 640 × 480 pixels. Its most important feature, however, is the built-in intelligence that greatly facilitates developers who want to integrate the display modules in their application. The device also provides acoustic feedback in addition to outputting information on screen, thanks to the integrated sound module that can play start-up tones, confirm keyboard inputs, and issue warning messages. A virtual on-screen keyboard rounds off the list of convenience features of the EA eDIPTFT57-A. The intelligence of the display unit makes it easy to program interactive user
16
interfaces. In conjunction with the optional touch panel, developers can create a virtual keyboard in just a few steps. Keyboard inputs are processed directly on the display in an “edit box”. This allows operators to use standard text formatting commands without placing a large workload on the programmer. A high-level language macro programming facility is an important aspect of the integrated intelligence of this display and
represents an elegant way of developing applications. ELECTRONIC ASSEMBLY www.lcd-module.de

neers. High-level language functions eliminate the need for system-level programming by the customer. The display controllers are shipped with an extensive set of sophisticated, pre-packaged graphic functions such as animation and bar graphs. Developers can access these features with simple function calls. There is no need
to write and test assembler programs for these functions. Many of the displays run right out of the box. The customer can get products to market much quicker and at lower cost. Electronic Assembly has its own engineering development group and helps shape the technological landscape. In-house production, which is not necessarily the norm in today’s market environment, puts the company in full control of quality and gives it that little bit of extra flexibility which from the customer perspective often makes the crucial difference.

High performance SPECTRALUX® light engines from OMC deliver 130 lumens/watt
Multi-angle LED light tubes from OMC are bright, robust and long life
OMC, the pioneer in optoelectronics, have launched new light engines which offer very high luminous efficiencies of up to 30 per cent higher than alternatives currently available. 220-series SPECTRALUX® light engines deliver up to 130lm/W and feature life expectancies of up to 40 years. In the SPECTRALUX® light engine range, highly efficient, tightly-matched LED die material is bonded to a thermally conductive substrate and encapsulated with a precision-applied phosphor coating. OMC is able to achieve such high performance in the 220-series because the company uses a greater LED chip area which has been optimally distributed across the substrate surface to enhance optical efficacy and reduce current density. In addition, the electronic configuration of the die elements has been arranged to keep drive currents
OMC, the pioneer in optoelectronics, today announced a new version of their rugged, robust and high-brightness multi-angle LED light tube range which can be used to replace traditional light sources in hundreds of applications, saving power and lasting much longer than fluorescent products. These compact, low voltage linear LED lighting fixtures feature advanced lens/reflector assemblies that provide extremely bright and uniform illumination across a broad and well-defined target illumination area, with a power consumption of just 2.9W per foot of tube. With a slim profile and robust metal housing, the new light tubes are easy to install and require no additional fixtures or fittings – they are simply screw-mounted to the installation surface using the range of secure, multi-angle brackets provided. The adjustable mounting brackets allow the light to be directed to where it is needed,
low, thereby reducing the power dissipation further. Not only does this technique result in high luminous efficiency, it also ensures that heat is spread more effectively across the substrate surface resulting in lower junction temperatures and longer life
expectancy. In applications where very high efficiency is not the main consideration, the die area can be tailored to reduce power consumption or cost so as to meet the requirements of individual customer applications. OMC www.omc-uk.com
and low voltage 24V DC operation means that they are safe and simple to power electrically. Available in one-foot to five-foot tube lengths and dimmable using OMC’s range of controllers, the new LED light tubes are suitable for a wide range of applications in both the commercial and industrial sectors, such as food cabinets, vending machines, CNC machine lighting, POS displays, shelves and
cabinets, architectural lighting, freezers, refrigerators and chillers, vehicles, and office, factory, garage and shed illumination. OMC www.omc-uk.com

AVX exceeds 100V milestone with new high voltage tantalum polymer SMD capacitors AVX Corporation is now exceeding the 100V milestone - which is almost twice the rated voltage of similar products on the market today - with the introduction of its new high voltage TCJ series 6.8μF/100V (V case) and TCJ series 3.3μF/125V (D case) tantalum polymer SMD capacitors. Following the award winning 50V TCJ series capacitor released in 2010 and the 63V and 75V versions launched only in spring 2012, the new components offer the benefits of great capacitance, high voltage, and low ESR technology in a small case size. Maintaining 20% recommended voltage derating, TCJ series capacitors significantly extend the usable voltage range. This unique combination enables design engineers to replace up to two of the highest rated component values in this technology by just one component. AVX’s new

SENSORS DESIGN
MEMS sensors Industrial applications requiring a fine touch MEMS sensors have already established themselves in mobile phones, tablets and so on. But these tiny sensors can provide more safety, more security, more convenience, more comfort and less power consumption in industrial, medical and home appliance applications too. Micro-electromechanical systems (MEMS) combine logic elements and micromechanical structure on a single chip. Tiny measurement sensors measuring thousandths of a millimetre such as springs, bars, weights or diaphragms are etched directly into the silicon layer and can detect linear acceleration, rotational speed, pressure or sound. The weak signals are processed or amplified by the integrated electronics and delivered via an analogue or digital interface. MEMS have made many innovative applications possible – as acceleration sensors, as gyroscopes and microphones with tiny dimensions. They were pioneered by the consumer, mobile communications and automotive markets. They were the first to recognise the uses of MEMS sensors, be it for consoles that allowed users to participate in the Olympic Games in the comfort of their living room, in mobile phones that react to movement, in cameras for image stabilisation, or in airbags and ESP in cars. In light of this, the global market for MEMS is growing constantly, currently by around one billion dollars a year. Global MEMS market leader Bosch sold one billion units in the thirteen years between 1995 and 2008, with the second billion taking just three years. STMicroelectronics is also pleased to have experienced such a sudden rise – in 2011, the company grew its MEMS sensor revenues by an enormous 80%, primarily in the consumer and mobile sector, and is thus now among the market leaders in this segment.

The experience gathered here is something that the company would now like to use in other markets. There's more than enough potential – MEMS sensors open up entirely new applications practically everywhere and can make existing applications more convenient, safer, more secure and more energy efficient, or even add new features to stand out from the competition. The revolution that occurred in the mobile phone market is yet to occur. More operating comfort A promising field of use is that of humanmachine interfaces (HMI). This is where the experience from use in mobile phones can be exploited, with the tap and double-tap functions simply copied over. A type of HMI can also be implemented with voice control, with mobile phones demonstrating the opportunities – iPhone users can already use 'Siri' to man-
age their appointments or emails. Such voice recognition and control technology is also made possible using MEMS microphones in other devices, such as navigation systems. These combine small sizes with high audio quality and robustness. These benefits are also provided in hand-free kits or conferencing systems – without any additional costs. Omron, for example, offers MEMS microphones in the price bracket as traditional electret condenser microphones (ECM), but are more reliable and more robust. ST designs its MEMS microphones with a unique plastic packaging that enables slender form factors and a longer life than conventional metal designs. The highest quality MEMS microphone from ST, the SNR model, is also suitable for applications with stricter requirements than consumer applications, for example in phonometers and sound-level meters, which require a high dynamic range.

More safety Rotational speed sensors are an example of how safety is being improved in drills. They detect the speed of the drill as soon as the drill
do not register movement within the certain time period. STMicroelectronics and Bosch Sensortec offer first-class products for applications such as these. The LIS3DH (STMicro-
Schematic diagram of a fill level gauge using an LPS331AP MEMS pressure sensor from STMicroelectronics gets stuck in concrete and ensure that it is shut down. Acceleration sensors make 'free-fall detection' possible, which is used predominantly at present in laptop hard disks. If the sensor registers that it is in free fall, it ensures that the write and read head does not crash into the disk, but rather is retracted in good time. This principle can be equally applied to a chainsaw or crane remote control, in order to make the device safe using an emergency shutoff system if it ends up in free fall. The acceleration sensors detect even the smallest movements and vibrations, meaning that oil and gas pipelines or vending machines can be protected simply and effectively against vandalism and valuable items can be protected against theft. Machines can be checked to determine if they are working correctly by detecting their vibrations. Barometrics MEMS pressure sensors are capable of measuring altitude differences to a precision of 25cm. Unless satellite-based tracking systems, which do not work in closed environments due to poor or no reception, these enable applications such as indoor navigation in shopping centres or car parks. These measure the air pressure, which can be used to determine the altitude and thus the storey. They are also used in navigation systems, for example to locate a vehicle in a multi-storey car pack. During fire brigade and police operations, MEMS pressure sensors can even help to save lives by locating accident victims in buildings.
electronics) and BMA250 (Bosch Sensortec) triaxial MEMS acceleration sensors are primarily recommended for use in mobile devices, because both are very energy efficient and small. The LIS3DH consumes only 2μA of power in ultra-low power mode, while the Bosch model requires less than 5μA in low-power mode. Its dimensions of 3 × 3 × 1mm (LIS3DH) or 2 × 2 × 0.95mm (BMA250) are ideal for applications where space is a commodity. Both sensors supply values to ± 2g, ± 4g, ± 8g and ±16g precision via programmable measurement ranges with a sensitivity of 1mg/digit with the LIS3DH and 256LSB/g with the BMA250 in the 2g range. Their digital resolution is 12-bit or 11bit respectively, the typical zero-g offset during the entire service life is ± 40mg for the ST model and ± 80mg for the Bosch model.
The BMA250 acceleration sensor from Bosch Sensortec uses little power and is small in size. The LIS3DH acceleration sensor from ST consumes only 2 μA of power in ultra-low power mode.
More efficiency If a machine switches off immediately when it is not working properly, this also increases their energy efficiency. This can be further optimised by combining multiple sensors. In a washing machine, for example, pressure sensors can measure the fill level and acceleration sensors can detect vibrations, thus enabling the machine to be controlled optimally in accordance with needs.

SENSORS DESIGN
For mobile devices, intelligent power management, free-fall recognition and the step counter function are also of interest. For HMI applications, the sensors provide the means to adapt the display and provide tap/double-tap control. They also support gaming and virtual reality functionality. Both manufacturers offer software and hardware tools for initial testing with a user-friendly GUI. These provide a clear means to adjust and test settings and copy them later one-to-one into the application. Both ST and Bosch provide programming boards and software with application programming interfaces (API). More mobility The various sensor types should not be considered in isolation, however. By combining them, they provide applications with a huge number of 'senses' that are almost identical to those of a human being. Acceleration sensors combined with gyroscopes, for example, are capable of generating complex movement profiles. Both sensors are also available in a single module, for example in the LSM303DLC from STMicroelectronics. In just 4 × 5 × 1mm, this module contains the LIS3DH tri-axial acceleration sensor and the L3GD20 tri-axial gyroscope. This offers a full measurement scale of ±250dps to ±2000dps and has a programmable interrupt. MEMS sensors or modules enable remote monitoring of patients or elderly people without limiting their movement. For example, if they fall, a nurse can be alarmed immediately, and mentally handicapped people who have got lost can be found again. Occupational
therapy, training for sportspeople and medicine dosages can also be fine-tuned to a specific movement profile and thus be designed to achieve greater effect. In blood pressure gauges, the sensor can check the position of the arm, thereby ensuring that they provide a correct measurement when used at home. In stock breeding, the sensor can be used to specifically measure out the amount of feed concentrate depending on how much the animal moves.
More degrees of freedom Sensor modules that combine a larger number of sensor types offer even more degrees of freedom (DoF). With their comparatively low sizes, they are primarily suited to space-critical applications. The most popular combinations at present are acceleration, gyroscope and compass sensors. STMicroelectronics recently presented a multi-sensor module with nine degrees of freedom. The iNEMO M1 integrates a 6-axis geomagnetic field sensor, a tri-
axial gyroscope and the 32-bit STM32 microcontroller together with special software – and this with a compact size of just 13x13x2mm. It can be used to fully detect and process linear acceleration values, angular velocities, free-fall acceleration and direction, meaning that direction, position and movement can be detected precisely. The sensor fusion software combines the output signals of all sensors, while prediction algorithms and filter algorithms automatically correct distortions and inaccuracies in the measurements. This is how the module achieves a higher degree of realism in gaming application, humanmachine interfaces, robots and portable navigation devices, as well as patient monitoring. Making use of the abundant opportunities The example show that the applications and opportunities provided by MEMS sensors are practically infinite. For developers that wish to use them for their application, however, they do also pose a challenge, because it is not always clear to begin with which sensor type would best serve their goals. A broad range of different models and manufacturers on offer ensures that your perspective is not obscured at the beginning of the development process. Rutronik maintains the by far most extensive range of sensors and MEMS sensors with innovative products from renowned manufacturers. The right solution can be created for every requirement using this broad palette. n www.rutronik.com/sensors

depending on your application needs. The standard detection distance for the silicon lens model is 3m and for the polyethylene lens type 5m, but the sensing distance can be increased up to 12m using the long-distance lens! Despite their miniature size and low profile, PaPIRs incorporate the best features of existing NaPiOn sensors such as an integrated amplifier and digital signal processing, which prevent erroneous switching caused by extraneous electromagnetic fields.

Remote Sensors Powered by RF Harvesting by Jason Tollefson, Product Marketing Manager, Microchip Technology Energy Capture Sources of energy, such as light, wind, temperature, vibration, radio waves and even PH have been converted to usable energy but the challenge is how to convert the tiny amount of energy generated to perform a useful function, such as reliably powering an environmental sensor. Figure 1 shows a variety of these energy harvesting methods. An examination of the power
scheduled basis or on demand. A rechargeable battery or super capacitor can store the converted RF energy for operation during the peak periods. Selecting a Low-Power Component A convenient and reliable power source is just the start; a proper system design is needed to maximize performance with the tiny amount of energy provided. This

budget holds the key, together with the harvested source and the components. RF energy can be obtained from ambient energy or controlled by the use of a dedicated transmitter. Devices using RF harvesting can be untethered and work in almost any environment. RF as a Power Source RF energy can be harvested from sources such as broadcast TV and radio stations, mobile phones and base stations, and transmitters in unlicensed bands including 915MHz, 868MHz or 2.4GHz, making it commercially viable worldwide. RF does not depend on the time of day or require exposure to heat or wind, and can be moved freely within the range of the transmission source. Energy can transmitted continuously, on a
can be addressed by either using extremely low power components or implementing power balancing. The trend for lower-power electronic components is fueled by consumer demand for portable products, and has delivered new low power microcontrollers, analog, radios and communication protocols that complement RF harvesting. Low power consumption levels are standard on Microcontrollers. Microchip’s PIC24F with eXtreme Low Power (XLP) technology consumes only 20nA while sleeping, and can execute code with currents as low as 8μA. Analog components and a radio are required to complete an environmental sensor. The radio stretches the powerbudget because of the protocol used and the Transmit/Receive
(Tx / Rx) current. New radios have started to address the issue, and now feature receive currents as low as 3mA, which helps to reduce power consumption, but the wireless communications protocol remains the driving factor. Balancing Power Long execution times and bloated wireless protocols will consume the power budget when working with the tiny amounts of power generated by energy harvesting. The key reduction is to select a protocol that allows for scaling functionality. Microchip’s MiWi™ protocol allows for minimalist implementation, with radio transmission times driven as low as 5 ms. Power management through charge-based execution and state-of-charge monitoring will deliver further improvements. Power is cut off completely from the sensor system in charge-based execution. When the RF harvester has collected enough energy the device consumes zero power while replenishing the energy reservoir.
Figure 2: Advantages of RF Energy Harvesting The frequency of the sensor’s execution is dependent upon the rate of charge to the reservoir. This is impacted by distance to the RF source, the receiving antenna, and obstructions such as walls, which works well when the sensor is located such that the frequency of sensor operation is fitted to the needs of the overall system. To avoid flooding the network with unnecessary packets the RF har-
vester can also use the received signal strength (RSSI) as a mechanism for controlling the rate of data transmissions. If the RF harvester is charging a battery, a microcontroller can be used to monitor the length of the charging cycle and estimate the state of charge. It can then calculate the run-time based on what sensor operations are performed by recording the current consumed during the various parts of the sensor operation. For example, the sensor node might consume 100μA when measuring the sensor’s output, and 20mA during the radio transmission of that data. The microcontroller can use this information to estimate the charge that will be depleted each time one of these functions is completed. The state of charge is thus found in the comparison between charging and depleting. This method can taper off the frequency of sensor transmissions, based upon state of charge and can even call for help, by transmitting a message to the RF power source to send more power. Energy Harvesting: The Practical Solution RF harvesting is a viable option for a wide range of applications with proven technology providing a platform for prototyping new products. Battery powered sensors can be replaced with a selection of components and power balancing. RF harvesting is a practical option providing control of the source and the ability to operate in any environment, which may also drive RF harvesting to the mainstream. RF harvesting is the first proven and reliable option; it meets environmental regulations and CSR requirements, makes economic sense and avoids being at the mercy of the sun, wind or unpredictable temperature conditions. n www.microchip.com

AUTOMATION AEQ microswitches from Panasonic the most energy-efficient way to reliably switch low level loads Nowadays, energy efficiency and caring for our natural resources is on everyone's mind. With the AEQ series switches, optimized specifically to handle low level loads in the ÎźA range, Panasonic Electric Works presents another trend-setting, environmentally friendly product. A newly developed contact system primarily differentiates the Panasonic AEQ series from conventional ultraminiature switches. Sliding contacts mean the contact force does not depend on the actuating path but rather ensure a stable and even contact force
across the entire actuating area. This innovative sliding contact system also guarantees bounce less operation. Over travel of 2.2mm on the NO
side and 2.5mm on the NC side enables a high degree of tolerance during the design phase and hence makes the switch attractive for a wide variety of applications.
In comparison to conventional microswitches, the AEQ series can reliably switch loads that are lower by a factor of 10.

SUYIN's new HD D-Sub socket – appreciating the “little things” in life By employing sophisticated design and production techniques, SUYIN has again succeeded in further reducing the width and length of its female D-sub connectors. Its 070546XR015 XX69XX model is a 15-position, right-angle high-density (HD) Dsub socket with extremely compact dimensions of just 20.6 mm × 10.9 mm (L × D). This reversed-type three-row Dsub connector is designed for through-hole reflow (THR) mounting using a pin in paste soldering process. Two soldering tags attached to the sides provide extra stability for anchoring on the PCB; they ensure a sturdy hold, even when high insertion and removal forces are applied. The number of mating cycles is specified at 5,000. Other technical specifications for this compact D-sub socket are a contact rating of 250VDC/0.5A per pin, a low contact resistance of 50mΩ (max.), an insulation
resistance of 1,000MΩ (min., initial) and an operating temperature range from –40°C to + 105°C. This lead-free, HD D-sub socket is specified in accordance with UL94V0 and is available in the colours black, blue and grey. They are supplied in reel packaging with placement caps. SUYIN offers
them beginning at order volumes of 80,000 pieces per year, and – of course – provides small batches to help you launch your project. Customer-specific adaptations are available upon request. SUYIN www.suyin-europe.com
SUYIN – Custom tailoring for connectors SUYIN’s primary strength lies in its ability to adapt connectors to meet its customers’ exact requirements as well as the needs of the given application in terms of form and function. To do this, SUYIN – as a Taiwanese company with production locations and development teams in China, but with technical support, service, sales and logistics teams based in Germany for its European customers – draws on both standardized subcomponents and on the tremendous expertise that it has developed in recent decades in areas such as industrial, automotive and communications applications. A good example for the design rule that “form follows function” can be seen in a RJ45 jack with a housing that has been adapted to match the product design precisely. This right-angle, surfacemount RJ45 jack with high-quality 8P/8C contacts (S1 to S6 with 5 μm to 50 μm gold plating over 30 μm nickel) is housed in a shielded plastic housing that has been

nicely rounded to match the design specifications. In accordance with another of the customer-specific specifications, mounting on the printed circuit board can be countersunk by 1.92 mm. Two side-mounted soldering tabs ensure an ideal fix on the PCB. All of the other technical specifications for the temperature range, dielectric strength,
number of mating cycles, insertion and removal forces, plating, and many other characteristics also match the requirements defined by the customer or by the relevant state-of-the-art standards. SUYIN www.suyin-europe.com

New Zero Insertion Force Quad Lock Connector for diagnostic and imaging medical equipment from ITT Cannon ITT Cannon has recently released a new Zero Insertion Force (ZIF) Quad Lock Connector (QLC) for use in medical imaging and diagnostic equipment. The device is an industry first which achieves a reduction in interconnect packaging whilst accommodating robust performance requirements and functional enhancements such as press-fit. Reducing the spacing from the standard DL line to 0.8mm made it possible for ITT ICS’ engineers to design the ZIF QLC portable connector system with a full 260 pin configuration and a reduced package size - it is up to 65% smaller than existing DL products and competitive QLC products currently on the market. This enables customers to achieve a drastic reduction in the overall size of diagnostic equipment. The high pin count of 260 positions offers multiple channel options and makes improvements to
image resolution possible at the design stage, which will ultimately result in enhanced diagnostic functionality. The ZIF QLC connector system exceeds 20,000 mating cycles - an industry “best in class”. Utilizing two 130 pin PCB surface mount connectors makes the Zero Insertion Force Quad
Lock Connector more flexible in customer PCB designs. The component incorporates a patented and unique extended insulator to secure the four locking pins and more than double the connection retention force. ITT INTERCONNECT SOLUTIONS www.ittcannon.com
