Microchip’s new embedded Wi-Fi® Development Boards integrate TCP/IP stack to enable Internet of Things via simple serial connection Microchip announces the integration of its Wi-Fi® modules from the recent Roving Networks acquisition into its flexible, modular Explorer development systems supporting all of Microchip’s 8, 16 and 32-bit PIC® microcontrollers. The RN-131 and RN-171 PICtail™/PICtail Plus daughter boards are the first two products developed by Microchip based on Roving Networks modules. These modules use a simple serial interface to connect with any PIC microcontroller, and expand Microchip’s wireless portfolio with the industry’s lowest power consumption combined with an integrated TCP/IP stack in a certified Wi-Fi solution. The Roving Networks RN-171 and RN-131 fully-certified modules, from Microchip, are
comprehensive networking solutions that include a true 802.11 b/g radio, baseband processor, TCP/IP stack and a host of networking application features. No external processor drivers are required, enabling Wi-Fi connectivity for 4, 8, 16 and 32-bit processors. This on-board-stack approach significantly reduces customers’ integration time and development effort in a small form factor, while offering ultra-low power consumption, down to 4µA in sleep, 35mA in receive and 120mA in transmit mode. The new boards allow designers to add WiFi connectivity to the entire portfolio of PIC microcontrollers, without integrating a TCP/IP stack and whilst using standard development tools, which speeds time to
market and reduces R&D resources. The RN131 PICtail Daughter Board (RN-131-PICtail) is priced at $44.95 each, whilst the RN-171 PICtail Daughter Board (RN-171-PICtail) is priced at $39.95 each. Both boards are available now. MICROCHIP TECHNOLOGY www.microchip.com/get/T074

Google’s Android Accessory Framework outlines several different options for accessory development. For designers considering developing Android-based accessories, this article covers some of the design considerations for determining which of the possible routes to take. Each application is different and these criteria may or may not change a designer’s mind, but knowing the options is the key to ending up with the best possible outcome. 12 Taking the ARM strategy to the next level ARM technology on x86 standard form factors. With the availability of the PC-like ARM processor technology, there is a huge chance to improve time to market and to reduce R&D costs by facilitating processor implementations via ×86 form factors. One example is the availability of the NVIDIA® Tegra™ 2 processor on Pico-ITX™ boards. What are the benefits?

One of TME’s suppliers is a manufacturer of high quality enclosures – FIBOX which has over 40 years of experience in their manufacturing. In 1966, FIBOX introduced for production modular enclosures made of polycarbonate resin (PC), that were the first of this type in the world’s market.
COMPANIES LOGISTICS 18 Higher availability, lower costs. More than two million electronic components with different, partly extremely long and fluctuating delivery times are currently available in the market. Due to this huge variety, it can result in repeated supply shortages. When there are communication problems between those involved in the supply chain, the manufacturer produces and the distributor orders without knowing what customers actually need. Whether the customer then receives what they need in good time, is purely a gamble.

Personal vs Company IT Picture this – companies are recruiting now from a generation whose expectations of technology have been profoundly shaped by Facebook, mobile apps and other innovations. But it isn’t just “digital natives” who are shocked by the state of technology in their workplaces. The rapid spread of tablets and smart phones, and the magnetic attraction of social networks and other online tools such as Twitter, mean that people of all ages have grown accustomed to having powerful yet easy-to-use technologies at their fingertips. Many of them want the same stuff at work too. Their demands are also being fuelled by changes in the society. Among these is the increasing mobility of the workforce, whether commuting or visiting clients, which has made smart phones and tablets especially popular with corporate road warriors. There has also been a gradual blurring of the lines between personal and business lives, which means that people rely on technology much more to allow them to work or play anywhere at any time. As a result, one can notice two main trends. On one hand, people increasingly use personal devices to access business information, partly also because of the arrival of the tablets. This happens in spite of the concern companies have for data security. On the other hand, one can notice a constant influx of employee-owned gadgets in the workplace. As a result, many companies modify their IT infrastructure to allow a person to work more easily from different places, which means employees will be free to access the company data they need. No matter where we will be in a decade or so, it is quite certain that looking back then we will see a completely different world, which will be difficult to recognize. We will be amazed how primitive that world will appear to all of us. n (inspired by and adapted from The Economist)

Silicon Labs Obsoletes Optocouplers with Drop-in Digital Isolators Silicon Laboratories Inc., a leader in high-performance, analogintensive, mixed-signal ICs, introduced the industry’s first drop-in replacement for optocouplers based on mainstream CMOS technology and incorporating an innovative light-emitting diode (LED) emulator input. The new Si87xx digital isolators offer a perfect pin configuration, package and footprint fit for a number of optocoupler products while offering superior noise immunity, more robust performance and greater reliability, making them ideal for solar power inverters, switched mode power supplies (SMPS), uninterruptible power supplies (UPS), industrial drives, programmable logic controllers (PLCs), high-voltage medical equipment and other applications that often use optocouplers. Used for more than 40 years, optocouplers are inherently limited by outdated LED-based technology, which exhibits significant output variation over input current, temperature and age. These variations reduce the operating per-
formance and reliability over the optocoupler’s lifetime, resulting in increased design complexity and shorter life expectancy for end products. Because of their aging effects, optocouplers are often specified to last only 10 years, posing a serious problem for industrial system designers who want to develop products with 20+ year warranties. Silicon Labs’ Si87xx opto-replacement devices use a patented CMOS-based isolation architecture that is completely immune to the output variations that plague LED-based optocouplers. CMOSbased capacitive isolation technology provides more than ten
times the mean-time-to-failure (MTTF) rate of optocouplers. SILICON LABORATORIES www.silabs.com

Maxim Integrated’s Serial-Data Chipsets Transmit over Coax Cables, Lower Automotive Camera System Cable and Connectivity Costs by 50% Maxim Integrated Products, Inc. introduces two, high-speed serialization/deserialization (SerDes) chipsets that significantly lower the costs for automotive camera systems. Operating over standard coax cables, the MAX9273/ MAX9272 (22 bits) and MAX9271/MAX9272 (16 bits) chipsets do not need the extra wires of an Ethernet setup to power a camera. With today’s highend automotive camera systems often using multiple cameras and cables, this coax solution represents a 50% reduction in cable and connectivity costs compared to current standard twisted-pair (STP) solutions. Maxim’s new camera chipsets operate at very high data rates (1.5Gbps) which is critical for today’s fast video and megapixel image transmissions. Using coax cables, the chipsets do not need to compress data and thus process
images immediately - a crucial requirement for safety applications like sign recognition, collision avoidance, and night vision. In comparison, Ethernet-based solutions require data compression, which requires external components, resulting in higher costs, power consumption, and power dissipation. The chipsets’ reduced
power consumption, from both the elimination of external components and low 75mA supply current, helps to prevent camera heat sensitivity issues. MAXIM INTEGRATED www.maximintegrated.com

Options in Android™ Accessory Design with Google’s Open Accessory Framework by David Flowers Principal Applications Engineer - Advanced Microcontroller Architecture Division Microchip Technology Inc.
Google’s Android Accessory Framework outlines several different options for accessory development. For designers considering developing Android-based accessories, this article covers some of the design considerations for determining which of the possible routes to take. Each application is different and these criteria may or may not change a designer’s mind, but knowing the options is the key to ending up with the best possible outcome. USB Hosts and Peripherals USB is logically a point-to-point communication system between an attached peripheral and the host controller. Peripherals can never talk to each other through USB. There is only ever one host on the bus. Typically in a USB system, the USB host is the more powerful machine (more memory, more CPU power, better connectivity, and is going to typically be the focal point for the user), while the peripheral is often a simpler device with basic functionality on the bus as a service to the host. The host also has two key responsibilities on the bus; the first is to supply power to attached peripherals and the second is to manage the devices on the bus. Because of these differences, the USB host-enabled device and USB peripheral devices often have very different designs.
point for the user, and the accessory is likely going to be providing a service for the phone/tablet. Having the phone/tablet supply power to the accessory is also an attractive option. The option to use the Android phone or tablet as a USB host was enabled in the Android 3.1+ devices. However, this option is not available in other operating-system versions. Android Accessories as USB Hosts When Google released their OpenAccessory framework they recognised that many Android devices already in the marketplace were designed only for USB peripheral capability and as such these phones and tablets don’t have the hardware required to operate as a USB host.
Android Accessories as USB Peripherals At first glance, the choice between these two USB options might seem clear. An accessory to a smartphone/tablet makes the most sense as a USB peripheral. The phone or tablet is likely to be the central focus

Figure 1b: To create an accessory that needs to support Android devices that don’t already have USB host capability or are running an OS version that doesn’t support the USB hos, mode, the accessory must be the USB host and use the OpenAccessory framework to talk to the Android device. In order to enable these products to attach to an accessory, Google created an accessory framework option based on the accessory being the USB
EMBEDDED DESIGN
host and the Android phone/tablet being the USB device. This OpenAccessory-framework option is enabled in both the Android 2.3.4 and Android 3.1+ operating-system versions. Android Accessories for Standard USB Accessories A third option that is available is native OS support; with the addition of USB host capabilities to the operating system, support for some standard accessories such as mice, keyboards, thumb drives, etc. was also added. For USB peripheral manufacturers who make these types of standard accessories, they don’t need to worry about creating new devices or software to work with Android phones/tablets because their accessories will work on any operating system that supports that specific standard class driver. All three of these support options are highlighted in Figures 1a, 1b and 1c.
Figure 1c: Android accessory using a standard USB device class. Which Option Should I Choose? Each of the three available options has implications in the creation of an accessory. The first issue is the target set of Android devices for the accessory - In order to create an accessory that is a USB device, it requires the target Android phone/tablet to have the built-in hardware capability of being a USB host. Even if the hardware is capable of running USB host, unless the Android device is running Android 3.1+, it will not be able to use either of the USB host options. So an accessory
Standard or Custom Applications? In addition to the power-supply requirements, a designer must also consider how the accessory is going to be used and whether a custom application is acceptable. Any designer using the accessory mode, with the accessory as the USB host, will likely need to create a custom protocol for their application. Using the same two examples as before, the refrigerator and the pulse oximeter, it would be reasonable, or even expected, for the refrigerator to have a custom protocol, wherein the customer must use a vendor-specific application to talk to that device. The pulse oximeter, however, would likely want to use the built-in Personal Healthcare Device Class (PHDC) available in the USB protocol. Using this protocol allows the device to be used on any USB host machine, and allows the hardware to interface to a wide range of software. However, limiting this hardware to a vendor-specific application might be too constraining for consumers to accept. If an accessory should be compatible with Android devices that don’t have USB host functionality, either due to hardware limitations or because they haven’t received an OS update to 3.1+ or later, then the accessory must use a custom protocol, as seen in Figure 1b. For accessories that can be limited to use with USB-host-enabled Android devices, the choice between a standard USB class or a custom class is entirely up to the designer. Though the OS may not have native support for a device, a custom application should still be able to access the device. This also allows the Android phone/tablet to work on other USB hosts that may support that device natively. USB Physical Connectors While they may not be a major determining factor, the physical connectors might also play a role in deciding which mode is used. For an accessory that is acting as the USB host, the USB specification indicates that that accessory should have a full-sized, A-style female connector, like the connector found on a computer. Figure 3 shows how an accessory supporting a USB-peripheral-only Android device would connect to that device.
Figure 2: Android version adoption percentages, as of July 2nd 2012.
(Source: http://developer.android.com/resources/dashboard/platform-versions.html)
designer needs to weigh the options of cost/features against what the Android 3.1+ adoption rate will be when the accessory is released. As new Android devices are released to the market, most are including the latest versions of Android. Figure 2 breaks down the adoption rates for the various versions of the Android operating system. USB Host Must Provide The Power The decision to select accessory mode, where the accessory is the USB host, isn’t as clear cut as just looking at the version adoption-rate information. In a USB system, the USB host must provide power to an attached peripheral. Peripherals can request up to 500 mA of current from the host. Most USB peripherals expect that a host can supply at least 100 mA. While this might be a suitable requirement for a refrigerator doing diagnostics or firmware updates, it might be too large a limitation for a device like a pulse oximeter, where the consumer is expecting the device to be mobile, small and have a long battery life. Having to provide a minimum of 100 mA is a very large power requirement for many mobile applications. Figures 1a, 1b and 1c show how the power is provided in the three possible accessory configurations.
Figure 3: Accessories wanting to support Android devices that have only USB-peripheral capability can use the OpenAccessory framework to interface to the device; similarly to how the device connects to a PC. If the accessory is designated as the USB peripheral, designers have the option of using the full-size-B, mini-B, or micro-B female connectors. The other side of the cable must also be considered, however. For accessories that run as a USB peripheral, the Android device will be the USB host and most Android devices don’t have a full-size-A female connector, in which to plug a USB cable. For this reason, many of the Android devices on the market today that enable USB host mode require an adapter of some sort in order to use this functionality. In an ideal situation, the Android device would have a micro-A/B female connector, and the user would be able to use a micro-A to micro-B OTG cable to connect the accessory to the Android device and then use a micro-B to full-size-A cable to connect the Android device to a USB host, such as a standard PC. www.epd-ee.eu | October, 2012 | EP&Dee

Figure 4 shows how a USB OTG-capable Android device could connect to various targets.
Figure 4: Android devices having both host- and peripheral-mode capability, through a standard micro-A/B USB OTG connector, can connect to both a host-mode target (either PCs or accessories) or to USB peripherals (eg standard mouse and keyboard peripherals). USB OTG for Both Peripheral & Host If the choice between the USB host-mode accessory and USB peripheral accessory options is not obvious, or both are desired—USB host in order to support devices without USB host capabilities, and USB peripheral for those that do, in order to use standard software—then there is another option available. Android accessories can be designed as a USB OTG device. The USB OTG specification allows an accessory to be either USB host or USB device, based on the cable that is plugged into it. Using USB OTG, an accessory can be a USB host for Android phones/tablets without host capability, and a USB peripheral for those Android phones/tablets with USB host functionality.
tional micro-A cable would be required. Due to the various hardware connectors found on Android devices, this cabling issue is a significant challenge as only a micro-A to micro-B cable as a standard USB cable can be used, but many Android devices have either mini-B receptacles or custom female connectors. To further complicate the issue, there are some tablets and phones on the market that have OTG capability but are not using the micro-A/B receptacle. Instead, they use a micro-B receptacle with a custom, non-USB-compliant cable to enable the host-mode operation. Figure 5 shows how an OTG-capable accessory is able to interface to these types of Android devices; those with USB peripheral capability only, as well as those with USB host or OTG functionality. If the accessory mode is selected, with the accessory acting as the USB host, there is still one more decision that needs to be made—which API set to use. When the accessory framework was added to Android 2.3.4, it was added as a Google API add-on library. The library module used in Android 2.3.4 (com.android.future.usb) is slightly different than the library used in Android 3.1 (android.hardware.usb). The interface between these two libraries also varies, but the functionality is basically the same. The main consideration here is that the android.hardware.usb library is only available in Android 3.1+, whereas the com.android.future.usb library is available in both Android 2.3.4 and Android 3.1+ devices. It is also important to note that the com.android.future.usb library is not a required library in Android 2.3.4, so there might be devices that are running Android 2.3.4 but do not have support for these features. It is up to the device manufacturer to determine whether they will include this feature in their OS build. Using IOIO – The Android Debugger Interface One final option should be covered on the topic of Android accessories. The IOIO solution enables the development of Android-based accessories through the Android ADB debugger interface. This solution provides a method for enabling accessories for Android phones/tablets running Android 1.5 or greater, eliminating the issue of having to wait for the hardware manufacturers to push out Android 2.3.4 or Android 3.1+ to their devices before the accessory will work with them. There are also downsides to this solution as the following example, presented in the accessory development class at Google I/O 2011, demonstrates. While the ADB interface has not changed much in recent history, the presenters indicated that Google reserves the right to change this interface as it needs to on future devices, in order to enable development and debugger features for hardware and software developers.

Taking the ARM strategy to the next level
ARM technology on x86 standard form factors by Daniel Piper Product Marketing Manager Kontron AG
With the availability of the PC-like ARM processor technology, there is a huge chance to improve time to market and to reduce R&D costs by facilitating processor implementations via ×86 form factors. One example is the availability of the NVIDIA® Tegra™ 2 processor on Pico-ITX™ boards. What are the benefits? The current performance level and low power consumption of ARM technology, which is applied in standard tablet applications, make it particularly interesting for embedded SFF applications. Consequently ×86 embedded platform vendors now also enter the ARM technology market, as an addition to x86 technology. One strategy of these vendors is to level out the technological barriers between ARM and ×86 using scalable building blocks. This strategy is very appealing to a large number of OEMs - as this means they can obtain very scalable platforms with completed Board Support Packages for all popular operating systems. And thanks to the corresponding hardware-specific software the underlying hardware can be abstracted so that more and more homogenous, application ready platforms come into existence. For OEMs, swapping from one board, module or system to another becomes a relatively easy procedure. But this goal can only be achieved if vendors will ensure

Table 1: When comparing the three Pico-ITX™ feature sets it becomes apparent, that in terms of the most important interfaces like USB, Ethernet, graphics and storage for SFF devices, there are hardly any differences, so that basically, with the extension into ARM technology, scalability is further increased.

this with the right standardizations on board and software level and by offering extensive software services. Depending on the programming of the application and which operation system is employed, no software changes have to be made, or only very few. Further to this, ARM solutions are always available as full-custom designs on board and system level, so that OEMs can fully concentrate on their application development, without having to consider any individual differences. Standards alleviate implementation The hardware design on board level goes to demonstrate how easy the selection of the right CPU building blocks for the application can be. For example, the interface feature set of a Pico-ITX™ board with Tegra™ 2 from NVIDIA® is hardly any different from the Intel® Atom™ or AMD Embedded G-Series designs which are already available. The major difference is to be found in the processor and consequently in its performance class (see table 1). A major difference is that ARM processors are more dedicated and thus offer less generic interfaces like SATA or PCI Express which in ×86 designs are often used for connecting individual extension options. Having said this, many of the ARM SOCs have several UARTs, I2C and SPI interfaces. So, theoretically speaking, the generic interfaces could be levelled out with additional components and some development effort. That would, however, also level out the valuable energy-saving advantages which make ARM designs so attractive: The need for cooling is reduced, fanless designs are possible which makes them more failsafe and results in a better MTBF. Developing and manufacturing the systems becomes easier - and the systems lighter in weight - due to the lack of heat pipes, cooling elements or fans. But bringing back these generic interfaces is superfluous as, especially in SFF designs, the trend is towards less not more generic interfaces. Subsequently, the difference between the feature set of the Pico-ITX™ board is of little relevance. As the Pico-ITX™ format is standardized, the application-specific choice of the right ×86 or ARM designs can be carried out within one single ecosystem - and no technological barriers have to be considered. The mechanical compatibility to the whole existing product portfolio is a major advantage and goes to simplify system design. Even more simplified desings can be achieved if besides the mechanical design advantage, ARM based boards additionally offer a range of software benefits. For example, the extensive support for all operating systems which are currently available for these processors. With such application-ready platforms the time-to-market can be reduced significantly and with it the costs for development.
Pico-ITX™ board: SFF Singleboard Computer with NVIDIA® Tegra 2 Dual Core processor The Small Form Factor board in Pico-ITX™ format (100 mm × 72 mm), which is currently being developed, is equipped with a 1 GHz NVIDIA® Tegra™ 2 Dual Core processor and integrates a completely passive cooling concept while boasting very low power consumption of 3 watts and an attractive feature set: in addition to 10/100Mbit Ethernet, five USB 2.0 ports and up to 24 configurable GPIOs the ARM Cortex A9 architecture-based mini-board has a slot for Micro SD cards and 512MB or 1GB 32bit DDR-2 memory. The audio-visual experience is also worth looking into too: the integrated ultra lowpower (ULP) NVIDIA® GeForce® GPU delivers graphic performance for mobile devices in high-quality gaming console quality and can simultaneously stream two HD videos (1080 p). Displays can be connected via DVI-I for analog and digital signal transmission and via a 24 bit LVDS converter. Backlight support is provided by either an internal 5V intern or an external 12 V. Following audio support is available: via SPDIF and stereo line-in and line-out as well as MIC. A whole range of hardware accelerations for flash, video and audio codecs ensures fluent and brilliant playback of multimedia and web content.
New Mini-ITX embedded motherboard with NVIDIA® Tegra 3 processor Besides the Pico-ITX form factor, Kontron recently extended its ARM portfolio with a Mini-ITX form factor (170mm × 170 mm) motherboard, the Kontron KTT30/mITX. Thanks to its standardized form factor it paves an efficient path for OEMs to integrate ARM technology straight off-the-shelf and into their embedded applications. The Kontron KTT30/mITX is based on the NVIDIA® Tegra 3 processor with four ARM Cortex-A9 CPU cores each with up to 900 MHz. An additional core with up to 500 MHz clock speed reduces power consumption to less than 1 watt in phases, when just media playback or background services are running. With its integrated 12-core NVIDIA® GeForce® GPU for low-power applications, lifelike 3D graphics with dynamic lighting are possible at screen resolutions of up to 2048 × 1536 pixels. It also offers HDMI 1.4a and 24 bit LVDS video interfaces. Thanks to the integrated video encoder and decoder, as well as high resolution video playback it offers real time video compression, which can, for example, be supplied via the CSI/DSI camera port. Peripheral devices can be connected via three USB 2.0 ports and two RS232 ports. Operating system and application data can be hosted on the bootable eMMC. Two PCIe slots, one of which can also be used as an mSATA port, are available for application-specific extensions. An RJ45 Gigabit Ethernet port and analog audio-I/Os add the final touches to the feature set. www.epd-ee.eu | October, 2012 | EP&Dee

EMBEDDED DESIGN Scalability across all processor platforms Are ARM processors now integrated into the realm of ×86 form factors? Has this brought an end to the whole technology argument? If it was up to the embedded standard form factor vendors to decide, then, yes. Because at the end of the day, it is simply these vendors goal to deliver standard platforms to its embedded customers and to embrace new applications, which to date were not possible with all other existing processor implementations. A high level of scalability of the fitting standard form factors across all processor platforms makes a lot of sense, as then OEMs can port their applications more easily between RISC and CISC architectures. If additional hardware-specific software services are provided to realize the code modifications which are sometimes necessary, then the underlying processor architecture is less and less a fundamental criterion for decision-making. Two other factors will play principle roles: energy consumption and performance per watt. One could also say that the market has now entered an era – after the enormous successes which the ×86 technology inspired – in which thanks to the extensive software sup-
port, the borders of the processor technology are disappearing as the software ecosystem can be extended to further technology platforms. Consequently, the standard form factors on board level have to be extended to accommodate these new processor platforms. Wide range of services for direct entry In order to enable customers to make an immediate entry into the ARM technology, embedded platform vendors need to offer their ARM-based building blocks in a bundle with extensive custom design services, so that OEM customers can get integrated ‘applicationready platforms’ on board and system level either as standard or as customer-specific versions. Besides this individual hardware development service on board and system level, Kontron for example also focuses on providing extensive services for software development, which ranges from driver development and OS code adjustments to a broad range of application porting and validation services as well as hw/sw bundles including quantity licensing. Application developers profit from efficient migration, fast time-to-market and, parallel to this, can reduce development risks and cost, as application-ready platforms are available which
are already certified, so that the customer can completely concentrate on his core competence: application development. Needless to say, that embedded platform vendors need to support all the ARM-relevant operating systems. Apart from Windows CE 6 and Windows Embedded Compact 7 (WEC7) in particular Linux-based operating systems are supported on ARM products. VxWorks support is planned for TI processors. These operating systems are especially interesting for applications, which demand the highest availability and best real time behaviour. Furthermore, support of an ARM-native version of Windows 8 is in the pipeline. The Android operating system which is at home in the smartphone and tablet market is a must to open the door to the vast market of networked multimedia-oriented applications based on ARM technology which this relatively young operating system caters for. The BSPs are validated right up to system level which enables OEMs to focus on the application without having to train accordingly and this minimizes timeto-market and TCO. n www.kontron.com

ENCLOSURES DESIGN
Enclosures for electronic appliances by Grzegorz Gorzka, Transfer Multisort Elektronik
Transfer Multisort Elektronik offers a wide range of enclosures for electronic appliances. One of TME’s suppliers is a manufacturer of high quality enclosures – FIBOX which has over 40 years of experience in their manufacturing. In 1966, FIBOX introduced for production modular enclosures made of polycarbonate resin (PC), that were the first of this type in the world’s market. It opened a new era in manufacturing of box switchboards, which led to fast development of the company. Enclosures manufacturing takes place in modern facilities near Helsinki in Finland and Inchon in Southern Korea. The biggest share of FIBOX company offer belongs to MNX series enclosures Those enclosures are made of polycarbonate (PC) and ABS materials. There are over 260 items available (PC100/125HT, ABS125/60HG, ABS150/150XHG and many other) from that series with the dimensions from 100 × 100 × 35 to 255 × 180 × 175mm. Those enclosures have been designed to furnish and protect electronic and electric apparatus. FIBOX gives an opportunity of ideal fitting the enclosure to the needs of every customer, thanks to the sales launch of enclosures in two different types of locks. They are divided into transparent, darkened or grey covers. External side of the cover is equipped with a special depression designed for the assembly of a membrane keyboard (covers in the following sizes: 150 mm and 175 mm). The set with enclosure also includes corrosion resistant screws.
The FIBOX offer contains over 500 different standard enclosures made of: ABS, polyester enforced with glass fibre, aluminum and polycarbonate (PC). Those enclosures, due to their application, have been divided into several groups. 16

Additional option offered by FIBOX is fixing an additional panel with hinges, which enables simple assembly of electronic apparatus. Special holder enables its installation at different depths both in the basis as well as in the enclosure’s cover. The set includes: a basis with PUR seal and screws to the assembly / DIN bus and a cover with polyamide screws. Additionally, the MNX series includes enclosures which are equipped with overpresses for metric chokes (they are marked in the catalogue as PCM enclosures) which enables mounting of chokes. Thanks to this, it is possible to introduce all types of cables in an simple and fast way. Also, we can save a lot of precious time during the manufacture of appliances. For the installation of control buttons and signal lamps, FIBOX recommends the PICCOLO series which is also fit for mounting of sensors, terminals and electronic apparatus. This product line is available in the ABS material version (ABSF85G) and polycarbonate (PCB65T). The most important feature is the leakproofness class, thanks to the use of polyurethane seals (PUR) - IP 66/67, which ensures high leaktightness against dust and water (up to 15cm of depth). The scope of enclosures dimensions from 110 × 80 × 65mm to 230 × 140 × 95mm.
Thanks to their parameters, PICCOLO series products are used among others: in gas engineering, mining, but also in companies endangered with the existence of large quantities of dust. Those enclosures can be purchased in
two types of covers: grey – made of ABS material (ABSF65G) and transparent – made of polycarbonate (PC) (ABSF65T). Thanks to a smooth surface, we can easily make an overprint. FIBOX by wanting to reach even the most demanding recipients, introduced ATEX certified enclosures.

COMPANIES Logistics
Higher availability, lower costs More than two million electronic components with different, partly extremely long and fluctuating delivery times are currently available in the market. Due to this huge variety, it can result in repeated supply shortages. When there are communication problems between those involved in the supply chain, the manufacturer produces and the distributor orders without knowing what customers actually need. Whether the customer then receives what they need in good time, is purely a gamble.
by Joachim Kaiser Managing Director Logistics and Materials Management Rutronik Elektronische Bauelemente GmbH
Contemporary logistics systems are therefore based on a significantly closer cooperation between companies and suppliers than was previously the case. This includes a relationship of trust, which deterred many companies in the past. But an increasing number of them are seeing the advantages of such systems and benefit from virtually 100% supply security. A pleasant side effect is that they can simultaneously optimise their processes significantly, reduce process costs and increase process quality. Opening of borders In the traditional supply chain, every company border also represented a border in the value added and supply chain. Processes are usually uncoordinated between supplier, manufacturer and customer and communication is inter-
18
EP&Dee | October, 2012 | www.epd-ee.eu
rupted. Decision making, which goes beyond company borders, is therefore not possible. To nevertheless ensure their own supply, every party involved operates its own buffer stock. The main reason for introducing logistics systems is to reduce stock and procurement costs and to transfer them to service providers. Today, however, the securing of supply and process cost reduction are at the top of the list of priorities. Because the sheer quantity of components with their derivatives and the trend to release second or even third sources increasingly rarely, makes need-compliant procurement a real challenge. To ensure it, all contemporary logistics systems are based on a timely, precise and comprehensive exchange of data. Crucial is that the customer provides the distributor with long-term planning figures
and passes on all data at item level in an unfiltered manner. Because every manual influence with factors, which change the figures upwards or downwards, may result in supply problems at a later stage. Electronic data exchange A large number of IT systems with different data formats is available for electronic data exchange, which a distributor should be able to easily process. This creates the foundation for automatic procurement and supply processes, which are ultimately identical for every logistics system: the customer sends its detailed short-term and long-term forecasts to the distributor on a set defined weekday. The latter defines from the weekly planning the current need and supplies the required components in the corresponding units collected
COMPANIES Logistics
to the supply address(es) of the customer on a weekday that is also defined in advance. Due to the long-term planned figures from production, the distributor orders the items probably required with an advance of up to eight months from the manufacturer. A suitable backlog management of the logistics partner can also cushion longer delivery periods any time. To this end, the distributor automatically generates from the customer's forecast the orders with the manufacturer in a time window of up to one year. The manufacturer then keeps the corresponding production capacities in stock. In doing so, the customer retains best possible flexibility, because it does not need to determine the precise items until about four to six weeks before delivery date. At the same time, transport costs can be reduced in this way, which may make up a significant proportion of unit costs in particular for passive components. If the components can be shipped by sea instead of air freight thanks to a long advance period, the cost share drops from ten to about one per cent of the component price. If the customer does not have such planning itself, the distributor should be able to provide it. With the use of forecast models, which include figures from the historical use and production of the weeks ahead, for instance, it can generate an artificial forecast, which represents a good basis for the entire supply chain. This creates a real win-win situation for all parties involved: the manufacturer knows the requirement of the market and therefore has a solid indication for its production planning. The distributor has the security of having items in stock at the time of requirement even in the event of longer delivery times. And the customer benefits from nearly 100% supply security. It can also be maintained in the event of unforeseeable extensions to delivery periods – ash clouds, earthquakes or an unusual economic performance therefore become less terrifying, at least as regards production. Other benefits: as the company borders are permeable in such a logistics system and planning involves manufacturer as well as distributor and customer, one single security storage is sufficient for all three parties, which means that fewer capital commitment costs are incurred. As a rule, the distributor keeps in stock the customer requirement of the coming one to
two months in the security stock, which means that surprising additional requirements or production losses of the manufacturer can be bridged for several weeks. Leaner and better processes The basis for this kind of cooperation in the supply chain is electronic data exchange. Because this is the only way of transmitting the planning figures in good time and comprehensively on a regular basis and in sufficient quality. In addition to ensuring the supply, many process steps in procurement therefore become unnecessary – and quite automatically without a process analysis.
As such, the demand carriers are not required to submit requests or demands with procurement, for example, procurement does not obtain any offers and convert orders, in goods inwards, the verification, posting and merging of the goods and the work of the registration, i.e. the storage of the delivery note, the invoice and order processes, is entirely unnecessary. As the costs of manual activities are reduced dramatically, the process and procurement costs fall clearly. At the same time, the quality of the processes improves, as the risk of erroneous inputs or typos drops significantly. Contemporary logistics systems are also based on the three classic systems of consignation, kanban and delivery schedule. Which one suits the relevant customer best results from
the circumstances and relevance, which has a series of factors for the customer, e.g. how much room is available in goods inwards or in the warehouse or how continuously production is carried out. If these factors are interpreted correctly, the customer gets the system that meets its ideal requirement. Trust is the start of everything The fear of opening too strongly and being bound to the suppliers, has kept some companies from using such logistics systems until now. In particular during the internet boom, it was standard practice to choose suppliers solely on the basis of price without considering product
quality and availability. This narrow focus often resulted in quality issues and production losses, which frequently overshadowed the cost savings. Due to this experience and the fact that short-term orders with the strongly risen quantity of components are hardly possible anymore with the various and occasionally very long delivery periods, a different culture of trust developed in which customer and supplier work together more closely. Another consequence of this development is companies' focus on fewer suppliers. The impact on the process costs of the customer must not be underestimated: every supply partner has its own processes and its own contact, with which the order, the supply and the invoicing must be discussed. As such, not only the selection of the relevant supplier takes up time, but also the communication with every individual one. This means: the bigger the proportion of the requirement that a logistics partner can cover, the fewer suppliers a company needs. The time requirement and costs are reduced accordingly. A long-standing relationship of trust between the customer and supplier or distributor, which is contractually secured, forms a solid basis for such a close connection, which benefits all parties involved. n www.rutronik.com www.epd-ee.eu | October, 2012 | EP&Dee

POWER DESIGN
Are all those batteries really necessary? Boosting a single battery can replace multiple batteries to cut costs and size, explains Jason Tollefson, Mikhail Voroniouk, and Adam Jakubiak, Microchip Technology Inc. and Energizer Battery Company
Whilst rechargeable batteries are suitable for applications which have high levels of used combined with higher drain rate, a primary battery is still the easiest and lowest-cost design option for most portable devices and the one which can support a significant reduction in physical size. Regardless of whether the design is for a medical blood-glucose meter; a PC peripheral, or a camera, the goals will be to deliver intelligent control combined with the longest possible battery life, and reducing the size and weight of the end-product to make it more portable. Of course, deciding to implement a singlebattery design is just the start: there is then the decision to be made on which battery technology to use. Figure 1 shows a range of popular primary battery technologies, and their typical applications. For timers and watches, which have a comparatively low energy draw combined with an operational life of up to 10 years, small, lightweight lithium coin batteries such as Li/MnO2, are available in 13 different sizes. For portable products which have a low to medium drain rate, alkaline cylindrical batteries are available in three compact form factors: AA, AAA, and AAAA packages. Cylindrical lithium (LiFeS2) batteries offer just
20
EP&Dee | October, 2012 | www.epd-ee.eu
two form factors, AA and AAA, and are most suitable for applications with a medium to high drain rate, or which need to operate in cold temperatures. Compared to cylindrical alkaline batteries, the lithium alternatives are 33% lighter, provide higher reliability and have a
shelf-life of up to 15 years which is two or three times more than alkaline batteries. Single-battery designs Higher silicon integration and smaller passive components mean that the size of portable

POWER DESIGN
products is shrinking year on year. For most designs, the barrier to further reductions in size is the physical size of the battery cavity which may need to allow space for two or more batteries. The alternative is use a microcontroller which can run on a single 1.5V battery. A battery boost converter, such as Microchip’s MCP1640, provides a power supply by stepping up an input voltage up to a higher, regulated voltage, such as 2.0 to 5.0V. This means that the device can start up with an input voltage which is significantly lower than the operating voltage. Many microcontrollers, for example, cannot operate with a voltage which is lower than 2V, whereas the boost converter can provide the voltage from a startup voltage as low as 0.65V. Figure 2 shows a typical startup waveform, where the low-voltage startup begins to charge the output voltage up to the input voltage. Once the output voltage is charged, the N-Channel begins to switch, pumping the output voltage up, after which the internal bias switches from the input to the output. This enables an application using a boosted single alkaline battery to start up at any point in its discharge curve, provided that it has enough remaining capacity to operate the device. While a battery boost converter may be able to deliver a consistent output voltage from very low input voltages (for example 0.35V), battery suppliers, such as Energizer, do not recommend discharging alkaline or lithium batteries below 0.8V, as it can damage the battery.
Figure 2: Typical waveform for low-voltage startup using a battery boost converter. The advantages of using a single-battery approach depend on which type of battery is being replaced. For example, by replacing two alkaline batteries with a single alkaline battery saves both the space and the weight of the second battery although there is a tradeoff in the small amount of space required by the converter and its supporting components. Using a battery boost converter also maximises the system power efficiency by providing regulated power over the battery’s entire operating range. This regulated voltage can make the microcontroller operate more efficiently, by enabling it to run at a lower and flatter voltage. For example, reducing the microcontroller operating voltage from 3.3V to 2.2V
provides 1.8 times lower power consumption on the microcontroller side (voltage difference squared). Additionally, the boost converter provides short-circuit protection through current limiting. The OEM cost for implementing the boost converter with a single battery is a little higher than the cost of two alkaline batteries, but the consumer operating cost can be similar between the two approaches if the boost converter is operating at high efficiency. Adopting a single alkaline battery approach enables developers to shrink their product size without switching between battery chemistries from a legacy multi-battery alkaline design. Working with a single battery also simplifies the mechanical considerations of the battery housing and reduces the risk that batteries will be installed incorrectly by the user. Designers comparing the advantages and disadvantages of implementing a single alkaline battery versus a rechargeable lithium ion polymer battery will find similar but different reasons for selecting the single-battery approach. Because the boost converter provides a regulated power output, it allows the tuning of the voltage to maximise system efficiency. Similar to the alkaline example, the boost converter provides short-circuit protection through current limiting. The 352mm2 footprint for a single AAAA alkaline battery is smaller than a single lithium ion polymer battery at 650mm2 (31.0 × 21.0 × 3.5mm), even though they have the same volume (2.3 cc), assuming a two-sided board design. Using an alkaline implementation versus the lithium ion polymer simplifies logistics because it avoids the need for charging circuitry and conforming to lithium shipping regulations. For those applications where using a replaceable battery is more convenient, implementing a boost converter with a single AAAA alkaline battery can provide a 50-70% cost reduction for the battery portion of the system compared to a single lithium ion polymer battery plus a charge controller and charger. Comparing a single alkaline battery implementation versus a lithium coin battery demonstrates yet another set of conditions where the single battery approach is favorable. For this example, the comparison is between an AAAA alkaline battery with a 600mAh rated capacity and a CR2032 lithium coin battery with a 225mAh rated capacity. Similar to the lithium ion polymer example, using a single boosted alkaline battery avoids the need to conform to lithium shipping regulations. Cylindrical batteries, such as the AAAA, are more familiar to consumers than the coin batteries, and this makes it easier to ensure the battery is installed correctly. The footprint of using either power source is similar, with the single alkaline AAAA battery taking approximately 352mm2 compared to 314mm2 for the CR2032 lithium coin battery,
assuming a two-sided board. The single alkaline battery continues to benefit from the tunable voltage to maximise efficiency and provide short-circuit protection through current limiting. However, unlike the CR2032, the alkaline battery is able to deliver a higher continuous current. Specifically, the boosted alkaline battery can source 150mA continuously, while the CR2032 can only do that for very short pulses. Extended continuous current beyond 10mA from the CR2032 battery dramatically decreases its usable capacity and, even at 20mA, it can only deliver 1/5th the energy that boosted AAAA batteries can provide, as shown in Figure 3.
Figure 3: Comparison of current draw for a single AAAA battery and a lithium coin. System-level trade-offs While using a battery boost converter provides many advantages, such as enabling a microcontroller-based design to operate with a single battery, it is important to consider the system-level tradeoffs between a boosted single-battery implementation and a multiplebattery design. The efficiency of the battery boost converter is highly dependent on the current draw, as well as the input and output voltages. The dominant loss for a boost converter is resistance, so the efficiency of lower input/output voltages is lower than the efficiency of higher input/output-voltage applications, as shown in Figure 4. Other factors that
Figure 4: Boost converter efficiency dependent on current draw and voltage. can impact the boost converter’s efficiency are the resistive losses in the inductor and capacitors. Inductors with lower DC-series resistances, and capacitors with low ESR (Equivalent Series Resistance), allow higher efficiency with the potential trade-offs being size and cost. www.epd-ee.eu | October, 2012 | EP&Dee

POWER DESIGN
To support a lower system current draw, the boost converter may include a low quiescent operation mode that typically draws 20μA, and a shutdown mode that draws less than 1μA. When coupled with a microcontroller, a booster can provide a voltage to power the application in a sleep mode, using a coast-down method. The microcontroller turns on the boost circuit when the system voltage falls below a pre-determined level, then shuts it off to eliminate the operating current of the booster while continuing to power from the booster’s output capacitor. Using this method, the total power consumption of the MCU and the boost regulator can drop by as much as 87%. Implementing a battery boost converter does enable a design to reduce the overall system area by the size of the second battery, with the trade-off of including the boost converter, two resistors, two capacitors and an inductor, as shown in Figure 5. The weight of the boost converter and its accompanying components is negligible for most designs. The area of a typical boost-converter circuit is approximately 60mm2, which is considerably smaller than the 450mm2 area of a second AAA battery or the 352mm2 area of a second AAAA battery, and still yields a 290 to 390mm2 area reduction in the overall system, assuming a 2-sided board design. The OEM cost to implement the boost converter and its accompanying components is about $0.20, which may or may not be offset by the alternative battery technology which is being replaced.
Many semiconductor companies offer application notes and/or reference designs for their boost converters, such as Microchip’s MCP1640 single AAAA battery boost converter reference design, shown in Figure 6. Modifying this pre-engineered circuit for a specific application can save a considerable amount of design time.
Flashlights, especially LED flashlights, can also benefit from a regulated supply voltage by using the boost converter to power a microcontroller, which in turn controls a more complex supply for the LEDs. The regulated supply can avoid a dimming of the flashlight as the battery discharges to provide consistent lighting through to the battery’s end of life.
End-product benefits A boosted single battery implementation not only enables differentiation through a smaller form factor for many applications, but it can provide a cost advantage over using coin or rechargeable batteries. Being able to minimise the width and weight of an electric toothbrush’s handle enables the handle to feel more natural in a user’s hand. Using a single battery also simplifies the mechanical design effort to ensure that the user has installed the battery correctly.
Using a boosted, single alkaline battery can be appropriate in value-priced devices, such as a portable, wireless mouse. A value-priced mouse focuses on longer battery life by operating with low-frequency positioning updates appropriate for Web browsing and text editing, as opposed to higher-frequency updates for gaming. Wireless mice are able to deliver a compact form factor with the single replaceable battery, and save on design and materials cost versus implementations that rely on a rechargeable battery. In addition to the cost difference between the battery technologies, using a replaceable battery means the mechanical design avoids including an expensive connector for a recharging source. Most consumers are familiar with AA, AAA, and AAAA cylindrical form factors, and they know where to acquire them. Designs using these form factors can provide a simpler access hatch to replace the battery, so that the user is confident the battery is installed correctly. While other form factors, such as a coin battery, are not unusual, most consumers are not as familiar with the notations for the different coin form factors – nor are they as familiar with ensuring that the battery is installed correctly. The clear orientation for installing a cylindrical battery and ease of acquiring replacement batteries provides an ease-of-use differentiation for a design.
Another benefit of using a boosted battery is that the power supplied to the device is regulated, so that it receives a flat voltage profile throughout the life of the battery. This enables the toothbrush to provide a consistent vibration throughout the life of the battery, without a noticeable drop-off in vibration strength and performance, as the battery discharges. Additionally, the microcontroller can modulate the vibration signal, such as generating pulsating vibration to signal to the user that the battery is approaching an end-of-life condition.
Boosted equipment can also be differentiated by incorporating RF connectivity in the volume that was freed up by using a single battery. Applications that can benefit from this are portable medical equipment, such as bloodpressure modules and blood-glucose meters, as well as beacons used in industrial environments for tracking transportation containers.

Summary Replacing multiple-battery designs with a single battery and a battery-boost converter, such as Microchip’s MCP1640, has real benefits for a wide range of portable applications. Using a single boosted battery can enable designs to gain a competitive edge by becoming smaller and lighter, with a lower cost of materials and more straight-forward mechanical design than using multiple batteries. End-users benefit too because of the wide-spread availability and familiarity with cylindrical batteries. All of these are valid reasons for moving to a single-battery design for portable devices. n www.microchip.com

CUI Introduces the Industry’s First No-Bus Self Compensating Digital Point-of-Load Modules CUI Inc releases the industry’s first self-compensating No-Bus digital point of load dc-dc module family. The modules are specifically designed for customers who value the efficiency and compensation advantages inherent in digital power but do not want to incorporate digital bus communication in their systems. The NSM2P series will allow customers to access many of the same features as a fully digital POL, however the access will be via header pins that will connect to a USB dongle and CUI’s Digital Power GUI. The designer can dynamically test and manipulate the desired functions within their system, monitor the results, and set the desired fault management functions. In production, the engineering header is pulled and the specified parameters are loaded into the module by CUI based on the customer’s specific requirement. The NSM2P has the same features
and functions of the recently announced NDM2P series without the need for a serial bus connection on the board, also offering true cycle-by-cycle self compensation, autonomously balancing the trade-offs between dynamic performance and system stability. With this feature, designers are able to bypass the traditional practice of building-in margins to account for factors such as compo-
nent ageing, manufacturing variations, and temperature, which inevitably lead to higher component cost and longer design cycles. CUI www.cui.com

Power Integrations Launches TinySwitch™-4 Off-Line Switcher IC Family Power Integrations introduced the TinySwitch-4 family, the latest generation of its industry-leading TinySwitch series of off-line switcher ICs. Featuring line-compensated overload power protection, TinySwitch-4 devices dramatically reduce the maximum overload power that can be delivered into the load over the entire AC input voltage range. The devices incorporate a 725 V MOSFET that easily allows 80 percent de-rating for high reflected voltage and high bus-voltage designs. Efficiency of greater than 70 percent at five percent load enables designers to meet the stringent European standby specifications scheduled to take effect in 2013, while no-load power consumption of less than 30 mW at 230 VAC meets critical energy-saving requirements in the market today. The line-compensated overload power protection of TinySwitch-4 ICs is particularly helpful in appli-
cations such as PC standby and appliances where unusually high current demands from the load may be indicative of a fault. Prompt action by the power supply to limit the current to a
designed maximum value may prevent damage to the circuitry and enhance overall system safety and reliability. The BP/M pin permits the MOSFET current limit to be adjusted up or down, allowing designers to optimize power delivery and efficiency in a variety of physical implementations.

SENSORS INDUSTRY NEWS
Omron MEMS thermal sensors detect presence without motion New non-contact IR sensors detect occupancy even when stationary Omron Electronic Components has introduced a non-contact MEMS thermal sensor that can reliably detect the presence of humans in an area without the need for movement. The ultrasensitive sensor is an outstanding alternative to pyroelectric sensors or PIR detectors in home automation, building automation, healthcare, security and industrial applications.
The new Omron D6T is a super-sensitive infrared temperature sensor that makes full use of proprietary Omron MEMS sensing technology. Most human presence sensors rely on movement, but the D6T is able to detect occupation by sensing body heat and provides a more reliable basis for switching off lighting, air conditioning and other services when the space is empty. Conventional sensors often fail
to distinguish between an unoccupied space and a stationary person. This feature is a particular issue in healthcare system design, when detecting the presence of bed-bound patients in a room. As D6T sensors are able to monitor the temperature of a room, they can also be used to control the level of heating and air conditioning systems and maintain optimal room temperature levels without wasting energy. Unusual changes in temperature can also be used in other ways, for example to detect line stoppages, identify hot spots before a fire breaks out or in clinical applications to check whether a patient has left the bed. While standard thermal sensors are only able to measure temperature at one contact point, the D6T can measure the temperature of an entire area contactlessly. Signals generated by infrared rays are extremely weak. To achieve reliable detection, Omron has developed and manufactured every part of the new high sensitivity thermal sensor in-house, from the MEMS sensors to ASICs (application-specific integrated circuits) and other application-specific parts. The technology behind Omron’s D6T thermal sensors combines a MEMS micro-mirror structure for efficient IR radiation detection with a high-performance silicon lens to focus the infrared rays onto its thermopiles. Proprietary
application-specific integrated circuits then make the necessary computations and convert sensor signals into digital I2C outputs. All components were developed in-house and are fabricated in Omron’s own MEMS facilities. The result is high ±1.5°C accuracy with excellent noise immunity (measured as noise equivalent temperature difference) of 140mK.
With the cutting edge MEMS technology that is utilized in the D6T, Omron aims to contribute to creating new advanced energy-saving household appliances as well as home and building energy management systems and a wide variety of factory automation applications.
