DESIGN FEATURES 10 FPGAs Rev Up Motor Control System - Efficiency, Performance and Design Flexibility Electric motors collectively consume a substantial portion of global electricity. According to the research firm IHS Technology, 96 percent of a motor’s lifetime costs are represented by pure electricity costs. Regulators have imposed more stringent energy standards for them, and manufacturers are scrutinizing their sizable contribution to equipment total cost of ownership (TCO). This has led to more complex motor control designs that use sensor-based and sensorless feedback loops and advanced algorithms for more precise control and greater motor efficiency.
12 Adding Intelligence to Control There are few applications addressed by integrated electronics that don’t require some modest form of power regulation, be that a simple current/voltage supply or a more sophisticated and optimised solution.
18 Commitment phobic? Not us 19 Kinetis MCU: A low power profile In an embedded system, it is all about being more energy efficient across the application’s tasks, which can generally be broken into three phases: Initialization, Control and the Compute. To reduce power consumption the equation is simple, reduce the area underneath the curve; in essence, do more with less power and time.

Microchip Releases New Multizone Technology for Whole-Home-Audio and Multi-Room Applications Based on the JukeBlox® Platform
Microchip Technology Inc. announced from the Hong Kong Electronics Fair the release of its second generation multizone audio technology and a mobile app for use in whole-home-audio and multi-room applications based on the JukeBlox® 4 platform. The JB Multizone 2.0 feature enables tightly synchronized and highly robust audio streaming to multiple speakers in conjunction with the JB App, a turnkey mobile app that enables easy setup and operation of the wireless speaker. Whole-home audio and multi-room audio systems allow consumers to group speakers into a zone to play back a common audio stream. Consumers create multiple zones each with their own audio streams such as pop music streaming to a pair of patio speakers while the children play outside and soothing classical music to four speakers downstairs, while dinner is prepared. JB Multizone 2.0 utilizes advanced technology to reduce audio drops found in traditional Wi-Fi® streaming applications. Wi-Fi direct eliminates the need for each speaker in a zone to connect with the access point, thereby eliminating common problems associated with overloading access points. Bypassing the access point also reduces the RF bandwidth consumed by half resulting in increased streaming quality and/or the ability to add more speakers in a zone. The addition of Wi-Fi Multimedia (WMM) to Wi-Fi Direct reduces source to zone speaker latency and packet loss resulting in tightly synchronized audio playback with minimal audio drops. JB App is a complete mobile app that enables OEMs to quickly deploy a complete whole-home-audio solution without having to manage an app development project. OEMs can choose between source code for custom app development or simply rebrand the app for release to consumers. Consumers use the JB App to create and modify zones, select audio sources and easily connect the speaker to the local Wi-Fi network. JB App source code is available at no charge and supports both iOS and Android™ platforms. “JB Multizone 2.0 is a complete platform to quickly deliver a robust whole home audio solution to market,” said Sumit Mitra, vice president of Microchip’s Wireless Products Group. “The JukeBlox platform incorporates advanced wireless networking technology to create a first class consumer listening experience.” MICROCHIP TECHNOLOGY

FPGAs
FPGAs Rev Up Motor Control System Efficiency, Performance and Design Flexibility Electric motors collectively consume a substantial portion of global electricity. According to the research firm IHS Technology, 96 percent of a motor’s lifetime costs are represented by pure electricity costs. Regulators have imposed more stringent energy standards for them, and manufacturers are scrutinizing their sizable contribution to equipment total cost of ownership (TCO). This has led to more complex motor control designs that use sensorbased and sensorless feedback loops and advanced algorithms for more precise control and greater motor efficiency. Authors: Jason Chiang, Sr. Marketing Manager, Industrial and Ted Marena, Director, FPGA/SoC Marketing, with Microsemi (www.microsemi.com)
Motor designers also must support changing industrial control standards and technologies while providing critical system features that ensure safety, scalability and reliability. Meeting the twin goals of energy efficiency and enhanced system-level capabilities requires adequate processing power for algorithm processing along with flexible and scalable system architectures. Non-volatile, secure and low-power flash-based system on chip (SoC) FPGAs meet both challenges by delivering the necessary horsepower with a combination of both inherent and layered security and reliability with protected communications for Internet of Things (IoT) applications, and the ability to quickly and easily scale from small-footprint to feature-rich custom motor designs in a variety of multi-axis or high-RPM applications. The Challenges While traditional designs use simple scalar control, high-efficiency motors use FieldOriented Control (FOC) across all torque and speed ranges to significantly improve efficiency. Because it is current-controlled, FOC also optimizes power-inverter circuitry and the motor footprint depending on application requirements. It uses feedback looping, with or without sensors, and sophisticated algorithms to regulate key motor behaviors including speed, position or angle, torque, current, and flux. While microcontrollers (MCUs) and DSPs have traditionally been used for algorithm processing in singleand dual-axis designs, their processing capa10

bilities aren’t keeping up with growing multiaxis or high-rotation motor performance demands. Adding to the challenge, motor control efficiency is rarely the only concern, especially in connected factories where today’s Internet of Things (IoT) environment poses critical requirements for secure communications – something that flash-based FPGA architectures are ideally suited to address. On the power electronics side of motor control designs, there is also a migration from insulated-gate bipolar transistor (IGBT) devices to silicon carbide (SiC)
power MOSFET devices. SiC solutions provide higher bandgap for improved cooling (and therefore enable the use of smaller and cheaper heat sinks), greater thermal conductivity to drive higher power densities, and higher switching frequencies (greater than 100kHz) which result in smaller magnetics at the inverter stage. This, in turn, contributes to lowering the customer’s TCO. On the control side, higher switching frequencies are where DSPs and MCUs don’t fare well. Some DSPs may optimize a few channels for high-frequency switching, but they still lack

DESIGN
the ability to quickly adapt to changing requirements, and to add more pulse width modulation (PWM) channels to control the power electronics stage (in fact, this is often offloaded to an FPGA). ASICs and ASSPs have the same flexibility and scaling challenges. Flash-based FPGAs offer greater performance than MCU/DSP-based solutions for high-speed, low-latency algorithm processing, while enabling the integration of additional system functionality to further improve TCO. Designers can use the flashbased FPGA to go beyond what MCUs/DSPs can support when scaling to higher switching frequencies and more PWM channels to match the power electronics. Figure 1 shows a solution where a flashbased SoC FPGA with an ARM® Cortex-M3 microcontroller can be used for motor control and monitoring functions. The FPGA fabric is used for hardware acceleration of motor control functions to improve performance, and for design flexibility. Motor control algorithms can be offloaded to the FPGA for faster parallel processing, with intelligent partitioning to ensure that all communications protocols in the microcontroller subsystem can be handled with zero impact on the motor control algorithm calculations that are running in the FPGA. Capping off today’s FPGA solutions are modular suites of plug-and-play IP blocks tailored for implementing all necessary mathematical motor models. Developers can determine which IP blocks to hardware-accelerate in the FPGA fabric so they can meet the full range of algorithm processing challenges. These solutions ensure low-power operation while enabling developers to optimize their systems for reliability, safety and security using a simplified design process that speeds time to market while providing the flexibility and scalability to meet evolving needs. Low-Power Operation FPGAs used for motor control design must reduce both static and total power, especially at high frequencies and temperatures. FPGAs that feature an embedded single-transistor flash cell offer an advantage as compared to alternatives that use a six-transistor SRAM cell that must be configured from an external ROM during power-up. The latest flashbased FPGA solutions also use a comprehensive approach to minimizing power that encompasses process technology, architecture and the design of configurable logic, as well as embedded features including a hardened M3 MCU, 5G SERDES, DDR2/3, TSE,
FPGAs
DSP blocks, and special power modes. This approach results in 50 percent lower total power and 10 percent lower static power than SRAM-based FPGA solutions. Reliability, Safety and Security In general, an FPGA is more reliable than a microcontroller for implementing motor control and network functions where deterministic timing is important. While there can
hardware to ensure precise torque output, and easily integrated to create task-specific modules.

Adding Intelligence to Control There are few applications addressed by integrated electronics that don’t require some modest form of power regulation, be that a simple current/voltage supply or a more sophisticated and optimised solution. However, with an increased focus on efficiency at every level it is becoming common to extend the simple to include some form of intelligence. Even a relatively unsophisticated control algorithm can deliver performance benefits such as reduced power consumption, while with a little more effort any device can now include more advanced features such as maximum power tracking, refined battery charging, environmentally aware settings and improved fault tolerance. This is a perfect scenario for low-cost microcontrollers, even the smallest device is now powerful enough to execute complex algorithms, while providing machine- and humaninterfaces. The ability to accommodate some form of standardised communication interface, such as SMbus, LIN or Ethernet adds another level of value. Author: Joseph Julicher, Engineering Manager, MCU08 Applications, Microchip Technology Inc.
Risk & Reward A ‘low risk’ method of making power smarter is to simply monitor the supply using an MCU and relay the parameters it measures to a back-system over some form of communication interface. This approach needs minimal additional components and design effort; typically restricted to adding some method for sensing the voltage, current and perhaps temperature. Monitoring other parameters, such as duty cycle or supply frequency will allow more sophisticated control over power-specific features including voltage levels. There exist a number of Switched Mode Power Supply ASSPs that offer a method of 12

modifying its functionality based on decisions made through measuring critical parameters. It offers a simple way to increase efficiency and is a task that can be handled by a wide range of microcontrollers; serial interfaces effectively enables an MCU to modify the functionality of the power supply based on monitored parameters. A further benefit of this approach is that the power supply itself remains under the control of the SMPS ASSP, which means the design team need not have any specific power supply design knowledge beyond understanding the parameters available for modification, and the affect of that; the key
control theory remains the domain of the SMPS engineer. The next step along the implementation curve — and one that offers potential cost savings — is to integrate the SMPS ASSP and MCU functionality in to a single device. It is increasingly possible to achieve this in a high-performance MCU that is closely integrated to a fast sampling ADC; an approach that affords a fully digital, all-software implantation. Of course, this approach incurs the need for greater SMPS design expertise, and the overall performance will be related to how much processing power the MCU can deliver (often limited by system-level power requirements).

POWER
The Hybrid Approach The middle-ground between the two scenarios described above is what some term the Hybrid Approach. In this case, a mixed-signal controller which integrates the necessary analogue peripherals are, again, fully integrated and one such device is the PIC16F753. This device features an operational amplifier, slope compensator, DAC, comparators and PWM controller in a single 14-pin MCU. Each of the peripherals is programmable, allowing them to be combined in a variety of ways to create a large number of current mode power supplies. As they are software-controlled, configuration is dynamic, allowing it to adapt to changing power supply conditions. This could see the device configured to operate as a hysteretic controller with a simple firmware feed-forward regulator when in standby mode, but allowing the supply to be quickly reconfigured for continuous current mode at a different operating frequency when more power is demanded. Because the supply’s control resides entirely within the MCU there is no need for additional components to be added later in the design cycle, which has the added benefit of both simplifying the design and lowering the component count. Furthermore, as the solution is fully integrated the firmware has total visibility of the power supply parameters without significantly changing the design process, while the communications and intelligence interface can be developed and verified by the power supply engineering team.
Figure 1 Figure 2
A typical power supply based on the PIC16F753 is shown in Figure 1; most implementations are minor variations of a common SMPS configuration. The Complementary Output Generator produces a complementary output with a programmable deadband from rising and falling inputs, while the CCP is configured to produce a programmable frequency rising edge. The comparator, C1, produces the falling edge when the current exceeds the output of the slope compensator. www.epd-ee.eu |

Figure 3a The CCP and C1 can be combined to create a maximum duty cycle, which is needed by some topologies such as boost, flyback and SEPIC. The operational amplifier, OPA, is used to provide feedback and compensation, while the DAC is used to provide the Op Amp’s reference (although the Fixed Voltage Reference, FVR, can also be used if programmable levels are not required). The slope compensator can be reset by the comparators or the COG, and it uses a programmable current sink to decay a pre-charged capacitor (in this case, the charge level is set by the OPA). This is a relatively simple configuration and Figure 2 shows an example of it operating as a boost supply regulating current in a LED string. The flowcharts in Figure 3a through 3c depict the levels of intelligence that can be added once it has been configured, allowing it target a range of applications.

Conclusion The addition of intelligence to a power supply has far-reaching benefits and can either be achieved simply, by adding an MCU, or more comprehensively by using a more capable, fully integrated solution such as a high-performance dsPIC or mixed-signal MCU that integrates all the performance and peripherals needed to realise a sophisticated single-chip SMPS. However it is delivered, smart power has the potential to impact significantly on electrical device operation and — more importantly — efficiency. With today’s highly capable, low-cost and fully integrated solutions, adding intelligence has never made more sense. ￭ The Microchip name and logo, MPLAB, dsPIC and PIC are registered trademarks of Microchip Technology Inc. in the USA and other countries.

High-Side Switch Boosts Throughput and Channel Density; Reduces Dissipation and Footprint
Maxim Integrated Products, Inc. addresses the need for higher throughput, smaller footprint, and lower power in industrial automation with the MAX14900E digital output switch. This eight-channel integrated circuit (IC) provides up to 70x faster speed, uses over 20% less power, and occupies 40% less space than existing solutions - all factors required in today’s faster, more localized, smaller end products. It is controlled by an eight-bit parallel interface, or via a standard Serial Peripheral Interface (SPI) which is also used for configuration and monitoring. Multiple devices can be daisy-chained to support additional I/O points via the single SPI interface, requiring only three isolators for all channels to provide further savings in cost, board space, and power. The serial mode includes cyclic redundancy checking (CRC) for assured data integrity, as well as global and per-channel diagnostics for remote system monitoring. Maxim offers both a complete reference design (MAXREFDES63#) as well as an evaluation (EV) kit with special prototyping features. The creditcard-sized reference design integrates the MAX14900E, a microcontroller, isolated I/O port, power supplies, UART, and USB port to simplify incorporating the device into the final OEM product design, as well as provide a means for quick evaluation. Key Advantages • Low power; high voltage: The eight digital channels require just 3mA (maximum) of supply current; operates from a wide supply range of 10V to 36V and thus compatible with the 24V rail of many factory systems. • High speed and drive: With an input-to-output propagation delay of 0.3usec (typical)/0.8usec (maximum), it can support fast switching rates of up to 100kHz in push pull configuration. On-resistance, a critical factor in static power dissipation is just 85mΩ (typical) and 165mΩ (maximum). It can drive current loads up to 850mA; outputs can be used in parallel to achieve even higher drive-current rating. • High integration and space savings: Housed in a tiny, 48-pin 7 mm × 7 mm QFN package; uses significantly less board space. • Data integrity: Offers per-channel and global diagnostics/monitoring via its SPI port, while users can access the I/O via an eight-bit parallel port. The serial link includes CRC error detection for enhanced data-link integrity. MAXIM INTEGRATED www.maximintegrated.com

Commitment phobic?
Not us By Michael Haight Michael Haight is in business development for the Microcontrollers Division at Freecale
“I don’t want to achieve immortality through my work. I want to achieve it through not dying.” – Woody Allen So then, can a microcontroller product line be immortal? Of course not, but many engineers wish they could continue to purchase the same microcontroller in perpetuity. And while not eternity, the proof of this desire is exemplified by some components of our MCU portfolio still selling in production for more than 25 years. Clearly, engineers value supply assurance or steady production availability for an extended period. The reasons vary. For some, their products are expected to be sold in the market unchanged for many, many years. For others, launching a product to market requires passing stringent certification and safety tests. Any changes later to the system components would require costly re-certification. 18

For many, the adage “if it’s not broken, don’t fix it” applies. To address this need, Freescale created the Product Longevity program – making a broad range of devices available up to 15 years. Longevity, in this use of the word, refers to the minimum lifetime commitment that Freescale makes. Not to be confused with product reliability that indicates how long a component can be expected to operate in a system, longevity refers to the minimum duration from component introduction that customers can expect to continue purchasing the component that is compatible with their system design. Understanding a component’s longevity is a key device selection criteria for a new system design.
So while not immortal, Freescale endeavors to perpetuate the lifetime of our customer’s products through the long-term supply of essential components. Take a look at the Product Longevity site at www.freescale.com/productlongevity and browse the list of devices that we plan to produce (and the terms and conditions for each) for at least 10 years, and in some cases 15 years.

Kinetis MCU: A low power profile By Justin Mortimer, Kinetis MCU product manager
In an embedded system, it is all about being more energy efficient across the application’s tasks, which can generally be broken into three phases: Initialization, Control and the Compute. To reduce power consumption the equation is simple, reduce the area underneath the curve; in essence, do more with less power and time. This is achieved by being best-in-class in not just one of these phases, but in all three. Our ever-changing world of electronics Electronics have made great strides since the first radio receiver/transmitter, a.k.a. the “walkie-talkie,” was introduced by Motorola in 1940. Since then, rapid advancements and breakthrough innovations continue to impact the way we interact with our world. We’re surrounded by embedded processors and sensors in battery-operated mobile devices like phones, tablets and other “smart” electronics. Ultimately, our world is driven by embedded software that constantly collects and interprets data to make real-time decisions. As consumers, we expect extremely high performance from our devices, and the growing expectation is that each product release will bring more functionality, longer battery life, lower prices, a better software experience, and a product safer for our environment. As the number of battery-operated devices increases, the importance placed on the embedded system to meet those requirements is that much greater. If you’re a design engineer, you know this all too well, which is why you will be glad to hear that the Kinetis MCUs are built around these requirements, especially power efficiency. Kinetis microcontrollers are driving low power, even lower In the past, integrated circuit manufacturers were pushed to deliver products with greater performance and integration. Today, expectations have been raised.
Energy efficient appliances, electric vehicles, LED lighting and televisions started the trend, but devices are getting much smarter: they are starting to make autonomous decisions without human intervention. Smarter integration, performance efficiency and creative solutions to solve the low power challenge have become a top priority for the integrated circuit manufacturers. The Kinetis MCUs have been built around reducing power consumption and will continue to differentiate themselves from other MCUs on the market. Driving down power consumption, one device at a time Here are just a few low power techniques integrated into the Kinetis portfolio, which help to reduce power consumption. • Low power boot: Optimized for the lowest power during the boot process by providing non-volatile control bits to set default chip clocking upon device power up • Smart clocking: Scalable performance, as needed to meet application needs, through various clock sources and multipliers to set the clocks for peripherals or CPU, across all power modes • Ultra-efficient processing: Real-time control and computation through the use of the world’s most efficient processor cores, the ARM® Cortex®-M, supplemented by Freescale proprietary hardware accelerators • Flexible low power modes: Numerous power modes to power gate memories
and peripherals, allowing for dynamic and static power optimization that fits a wide range of use cases • Autonomous, low power peripherals: Precious energy savings by enabling strategic peripherals to operate, and function with decision making capabilities, in power down modes, so that time spent sleeping can be extended Kinetis MCUs can make a difference, and will be there to help when milliamps make a world of difference Today’s embedded systems are not like the hardware-driven systems of our past. They are more complicated applications, with real-time tasks that include harvesting data from sensors, computing algorithms and making informed decisions. These applications require hardware that balances performance with power, but more so than ever, they require advanced software development. And as we move deeper into this new world, the need for power efficient devices is growing. The innovation driving the Kinetis portfolio is fueled by the desire to design microcontrollers that consume less power, offer flexible power modes, smarter peripherals, and tightly integrated software and enablement solutions.

Freescale seeded the effort by contributing our sensor fusion library, documentation and source files for Windows and Android-based visualization tools. We’ll be expanding these offerings in coming months. Steve Whalley, MIG chief strategy officer, added that “Analog Devices and NIST have already come on board, and PNI Sensor Corp. will contribute three algorithms: quaternion to heading pitch and roll; heart rate monitoring using PPG sensor; and step counting. We also fully expect other MIG member companies to add further algorithms to AIC over the next 30 to 60 days, providing a rich baseline algorithm capability to assist developers with sensor fusion solutions.” There have been a few sensor algorithm libraries on the web. But they were generally limited in ability or via license restrictions. Corporate acquisitions of Sensor Platforms, Movea and others earlier this year have taken a number of commercial offerings out of the general market. The AIC makes professional level solutions available for everyone else. Visit the MIG Open Source Sensor Fusion site to register and gain access to GitHub based code, documentation and tools. In the spirit of full disclosure, my team and I authored much of the material currently on the site, so if you have suggestions, please feel free to send them my way.
We’ve added a community support page at community.freescale.com/community/sensors/sensorfusion. But the really big news is that we’ve taken the entire sensor fusion library open source. It’s FREE. We got a lot of requests for less restrictive licensing terms and easier license checking in the code. We fixed both by eliminating all license checks, supplying the entire library in source form (no more node locked binaries) and switching to a very flexible BSD license file. Source files must retain the Freescale copyright, but you are free to use the code with any set of sensors or MCUs, at no cost what-so-ever. This is Freescale’s way of encouraging broad adoption of sensor fusion-based techniques, regardless of who your supplier is. Which leads me to…
AIC also opens the door for companies to provide professional support options, which Freescale plans start offering this month.

Ericsson converter brings unparalleled high power capability to highly demanding data networks Ericsson has introduced a new DC/DC converter module based on the company’s innovative and proprietary power topology known as Hybrid Regulated Ratio (HRR) technology. The latest member of the PKM-NH series, the PKM4817LNH has been optimized for parallel operation to power 2200W boards in extreme-data-demand applications in the datacom industry. Offering 800W of power per unit, up to three PKM4817LNH modules can be connected in parallel to achieve a total deliverable power of 2200W. Parallel mode uses Droop Load Sharing, which means the output voltage has a typical droop characteristic, whereby the output voltage slightly decreases when the load is increasing, while staying within system voltage limits.
Ericsson’s advanced HRR topology combines two power-control methods – voltage-regulation and ratio-regulation – and guarantees high performance across the 45V to 60V input voltage ranges commonly used in datacom systems that are powered by front-end rectifiers. HRR offers excellent response to line and load transients and guarantees the output voltage will remain stable and immune from voltage deviations that are due to power disturbances on the system bus. This means it retains intermediate bus voltage integrity within the tolerance band required by power system architects. Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules, says: “The ability to operate these advanced highpower-density DC/DC converters in parallel meets the increasing need in the datacom industry for ever higher power with boards now reaching 2kW. The combination of Ericsson’s HRR technology and the ability to easily parallel these new modules makes it possible to deliver the necessary high-density power required in extreme data traffic applications.” Available in a quarter-brick format with a footprint of 57.9 x 36.8 x 11.4mm, the PKM4817LNH operates with an input voltage range of 45V to 60V and delivers an output voltage of 10V-11V at 80A within the operational system voltage between 51V and 60V. Below 50V, in regulated-ratio mode, the output voltage self-adjusts for optimal operation and secures a stable voltage of 9.0V to 11V, even if the system bus voltage delivered via the front-end rectifier is operating abnormally.

power consumption,” says Matthias Keller, COO Components at Distec. “This concerns particularly the medium sizes since the eDP interface is available in all current Intel and AMD chips, especially in the notebook / ultrabook area. Therefore eDP replaces LVDS officially on PC platforms this year.” In addition to PRISMAeco-eDP the range of Distec’s intelligent eDP solutions includes the small LVDS2eDP interface. Integrated in the customer’s existing design, it simply converts the existing LVDS interface to eDP. Thus the customer may keep his controller solution but still use one of the modern, sleek full-HD displays (eg. 12.5").

“In modern TFT displays with full HD resolution, manufacturers are focusing more and more on embedded DisplayPort (eDP) as an input interface because compared to LVDS the eDP standard enables higher data rates and improved EMI performance at optimized
PrismaECO-eDP features an HDMI and a DisplayPort input. It controls TFT displays quickly and easily via dual-lane eDP interface and supports a resolution of currently WSXGA (1600×900) to WUXGA
(1920×1200). The brightness of the backlight can be controlled via Pulse Width Modulation (PWM) or analog voltage, but can also be adjusted automatically to ambient light conditions by using an optional ambient light sensor. A particular advantage of PrismaECO-eDP is the fact that it can be adjusted individually to the requirements of the application. The exclusive configuration software ChandlerRover enables for example port selection, timing, EDID programming and many other settings. This is particularly useful for system integrators who can adjust the PrismaECO-eDP individually for each customer. Your configurations and OSD menu settings can be downloaded from the EEPROM of the controller board and easily be transferred to other boards.

SMART ANALOG IC
Smart Analog / sensor technology Article The world of industrial automation is entering the fourth industrial revolution. A paradigm shift in which rising awareness of energy efficiency, environmental concerns and regulations, qualitative productivity and operational health and safety, contribute to the continued growth of machine to machine (M2M) technology. “Smart production” will become a norm in the manufacturing engineering sector, where intelligent machine systems, through networks interconnectivity will be capable of managing industrial production processes independently from human intervention, thereby making the “Internet of Things” a reality. Author: Bruno Nelta, Industrial & Communications Business Group Renesas Electronics Europe GmbH
The M2M communications are made possible with the use of industrial instrumentation comprising of intelligent sensors capable of capturing events (such as temperature, location, consumption, levels, movement etc.) and relaying the data over a network (wireless, wired or hybrid) to an applications (software program) that translates the captured event into meaningful information that can be analyzed and acted upon. Looking closer into the intelligent sensor system structure, the sensor (or transducers) are connected to one or more microcontroller units (MCUs) that are at the core of embedded system. The sensor’s output goes to the MCU’s input. The MCU processes that incoming signal and executes control functions accordingly. Depending on the application and situation, the sensor’s signal might cause the MCU to execute tasks predefined by the user. The purpose of a sensor is to detect or measure, while the purpose of the MCU is to execute control in accordance with the incoming information. When used together and properly interfaced, these components function as "detect and control" electronics, enabling greater functionality, convenience, safety and efficiency in embedded sensors systems. However the transducers’ output signal generated may be very weak, into a noisy envi24

ronment, or delivered in a format incompatible with the one required by the MCU. Almost all MCUs have built-in analog-todigital converter functions (ADCs or A/Ds) for translating analog sensor signals into a digital format. But those ADCs have restricted capabilities; for instance, they generally accept only a limited range of input voltages. To boost these signals to the level required by the MCU, or perform the necessary bridging (adaptation) function to implement signal compatibility between the transducer and the MCU, an Analog Front End (AFE) is necessary. Furthermore, the transducers’ output may contains too many unwanted frequencies. This noise must be removed before the analog signal is converted to digital. The AFE solution employs low-pass filter circuitry to block out highfrequency noise and/or high-pass filter circuits to remove lower-frequency noise. Until recently, analog circuits were typically designed manually by trial and error, which required a considerable amount of time and experience to complete a design, in some cases up to a year. Engineers today in the fast developing industry, are looking for solutions enabling them to reduce the development time of their analog circuit, and release their products faster to the market. To answer the needs, a new type of AFE
design approach was needed, which is easy to apply, flexible, quick and effective. After carrying out large scale investigation into analog circuit for sensors, the analog experts in Renesas’ R& D labs have perfected proprietary Smart Analog circuitry and development tools that can significantly reduce the time and effort engineers must expend to develop new AFEs. Using the programming side from the MCU, Smart Analog, makes use of the MCU to control the design of analog circuit, adjust its structure and its characteristics into a sensor application. Smart Analog circuits are designed at a computer screen using configurable designed operational amplifier circuits that greatly reduces the design time. As a sensor equipped system uses different type of transducers, for many different purposes, each of these sensors must have its own analog circuit. Renesas Electronics therefore designed a platform that enables the user to design the most basic analog circuit to the more advanced Op-amp based topologies, by selecting and combining appropriate types of Op-amp. The AFE Engineer is able to get his development projects up and running quickly and easily, with the powerful GUI-based sensor

SMART ANALOG IC
The Smart Analog platform approach is particularly versatile and convenient. It can be implemented in two ways. One method based on a Smart Analog IC, which is a single-chip silicon die implementation of an AFE. System engineers insert it into the embedded control system to connect the transducer to the MCU. The other one applies a Smart Analog MCU, a device that combines both AFE and MCU chips into a single, integrated package. The Smart Analog MCU combines a Smart Analog IC and an MCU into a space-saving, single-package device simplifying the design of sensor-based embedded control systems. Its internal MCU can be used to optimize the sensor compatibility of the AFE chip, as well as to control that chip’s signalinterfacing characteristics. Due to this unique combination of capabilities, the Smart Analog MCU is the only AFE solution that can handle the different outputs from diverse types of voltage, current and differ-
ential-output sensors. It provides enough connection terminals to accommodate all the sensors typically needed, eliminating the traditional requirement to have a separate AFE circuit for each sensor. The Smart Analog MCU helps shrink the circuit board, while simultaneously decreasing system component counts and costs. The reconfigurable characteristics of Smart analog, means that Engineers now have a field programmable solution which can be used to plan sensor sensitivity loss over time. Existing AFE design approaches make it necessary during the manufacturing process to perform manual trimming to compensate for variations in sensor characteristics. By contrast, a Smart Analog MCU automates this process with the implementation of automatic self-correction features. Thereby cutting system production and commissioning costs, while increasing the sensor-based system’s operating lifetime Using the new Smart Analog solutions, engi-

This flexible design capability significantly reduces the time that otherwise would be necessary for component selection, board design, and parts procurement. Now the AFE portion of the systemdevelopment process can proceed much faster and more efficiently. Smart Analog technology represents a new innovative platform for AFE design contributing to the implementation of enhanced features into intelligent sensors, with the added values of downsized systems, shortened design cycle and lowered system cost.

ASIC Redesign – The Answer for Discontinued Parts MAZeT Offers Redesign of Digital and Mixed-Signal ASICs that De-livers Long-Term Availability and Optimization MAZeT GmbH, specialized in the development and custom production of embedded systems and optoelectronics, devised a redesign strategy for digital and mixed-signal ASICs (application-specific integrated circuits) as an answer to discontinued parts. With this move, MAZeT is guaranteeing the future operability of existing electronics developments. “ASICs offer significant benefits compared to standard ICs,” explains Dr. Fred Grunert, Managing Director of MAZeT. “An electronics concept geared towards a specific application contains precisely the required function range, which consequently reduces costs and results in a compact solution. The electrical properties are also improved. On the downside, parts are only available for approx. six to eight years, and stock-keeping is limited to no more than two years. To help companies struggling with these issues, MAZeT developed the redesign solution. A redesign increases availability and also makes it possible to further optimize the ASIC.”
A mixed-signal ASIC contains digital modules as well as an analog part of variable size. The redesign effort is reduced by using analog or digital IPs, a database that is as complete as possible, comprehensive and detailed documentation of the ASIC, as well as a testing environment. When implementing a concrete redesign order for a mixed-signal ASIC, MAZeT eliminated the weaknesses of the original ASIC: For example, the previous 0.6 μm CMOS technology was replaced by 0.35 μm CMOS technology, which will be available over the long term. The entire pin assignment was retained despite the improved redesign, allowing the existing printed circuit boards (PCB) to be still used. Prerequisites for ASIC Redesign Successful ASIC redesign is subject to several conditions. The more of these are met, the lower the design risk, development time, and redesign costs. The top priority is to provide a technical description including a requirements specification, circuit plan,
high-level language description, netlist, and data sheet in order to ensure functional compatibility. The testing vectors and environment are essential for delivering the proof of functionality needed for series production. What is also important is the description of the dynamic behavior as the logic elements such as gates, flip-flops, memory etc. of a new semiconductor technology often exhibit different delay times and the analog transistors display a different electrical behavior, i.e., they represent different models. Other prerequisites include the testing program for the circuit tester, precise documentation of the ASIC’s electrical functions, the electrical characterization of the input/output behavior, the supply voltage concept, the ESD and EMC concept, as well as the GDS2 data set. MAZeT www.mazet.de
MAZeT is designing the new ASIC to be compatible to the original ASIC both in terms of its functionality and connection options, keeping follow-up to a minimum. The semiconductor technology is selected based on the premise that it is available over the long haul. MAZeT thus demonstrates that an ASIC redesign can be a highly efficient alternative. Digital and MixedSignal ASICs There are purely digital and mixed-signal ASICs. As concerns the redesign of digital ASICs, various methods are available, such as, for instance, maskprogrammable and standard-cell technology or replacement with a programmable logic module.

Design a 15Amp DC/DC Converter in 15 Minutes By Alan Elbanhawy, Principal Applications Engineer, Exar
The proliferation of fully integrated power modules allows power engineers to quickly design a fully functional, stable, efficient DC/DC converter that meets all system requirements. Using the XR79115 from Exar as a design example, we shall demonstrate that the design can be completed in a few minutes. Exar’s XR79115 is a synchronous step-down 15Amp fully integrated DC/DC converter that requires no control loop compensation because it employs a proprietary emulated current mode Constant On-Time (COT) control scheme. Design Procedure Step 1 Select the Soft Start Capacitor Place a capacitor CSS between the SS and AGND pins to program the soft-start, as shown in Figure 1. CSS can be calculated using the equation: CSS = TSS × 10μA / 0.6V Where: CSS = Soft start capacitor value in μF TSS = the soft start time of your choice Step 2 Select the DCM/CCM Mode The DCM/CCM mode is based on the control signal EN/MODE as
shown in Figure 2. If EN/MODE = 2V-2.8V -> CCM mode If EN/MODE ≥ 3.1V -> DCM/CCM mode Step 3 Program the On–Time The On–Time TON is programmed via the resistor RON shown in Figure 1 according to following equation: RON = ((VOUT /fSW × η) - VIN × 25 × 10-9) / 2.85 × 10-10 Where: VOUT = Output Voltage fSW = Desired Switching frequency η = Conversion Efficiency VIN = Input Voltage Figure 1: Typical Application Schematic

Figure 2: DCM/CCM Mode Selection Step 4 Calculate the Over–Current Protection (OCP) If the load current exceeds the programmed over–current IOCP for four consecutive switching cycles, then the power module will enter hiccup mode. The OCP current limit is calculated via the resistor RLIM shown in Figure 1 according to following equation: RLIM = (IOCP × RDSON + 8mV) / ILIM Where: RLIM = Resistor value for programming IOCP IOCP = Over-current threshold to be programmed RDSON = 5mΩ = MOSFET rated on Resistance Program the Output Voltage Step 5 Program the Output Voltage Use an external voltage divider feedback network as shown in Figure 3 to program the output voltage VOUT. Where: R1 = R2 × ((VOUT / 0.6) -1) CFF = 1 / (2 × π × 80KHz × R1) RFF = 0.015 × R1
IRMS = IOUT × √((VOUT / VIN) × (1 - (VOUT / VIN))) Step 7 Select the Output Capacitors Before starting this step, determine the maximum load current step you expect to encounter ΔIOUT, and the maximum voltage droop acceptable VDROOP. Typically the most important factor when determining the output capacitor value is the acceptable droop voltage during the transient response. Calculate the value of the output capacitor using the formula below. COUT = (KC x ΔIOUT) / (VDROOP × fSW) Where: KC = constant between 2 and 5 ΔIOUT = Maximum current step VDROOP = Maximum droop voltage fSW = Switching frequency Select ceramic capacitors with a ripple current rating greater than the RMS current. IRMS = (1 /(2 × √3)) × (VOUT × (VINMax-VOUT)) / (0.56 × 10-6 × fSW × VINMax" )
Figure 3
Step 6 Select the Input Capacitor Before starting this step, determine the acceptable input ripple voltage VPP. Then calculate the minimum acceptable capacitor value using the formula below. CIN(MIN) = 1 / (((VPP / IOUT) - ESR) × 4 × fSW) Where: CIN (Min) = Minimum acceptable input capacitor value VPP = Acceptable peak–to–peak input ripple voltage ESR = Equivalent Series Resistor of the selected capacitor IOUT = Output load current Select a ceramic capacitor with a voltage rating that matches the input voltage VIN with a 30% safety margin. The capacitor’s ripple current rating must be greater than the RMS current.

More for less
More efficient water meters thanks to new sensors
Higher precision at lower energy consumption – those were the Spanish manufacturer Mirakonta’s requirements when developing a new premium water meter. The focus of the project was on the sensor and Rutronik was on hand throughout to offer the company support.
The water meter needed to measure the water flow precisely with a battery-operated, radio-controlled counter. The sensor is positioned behind a 6 mm-thick glass panel in a housing made of stainless steel or aluminum, and the magnet is housed in an ethylene glycol antifreeze solution. A further sensor which detects the presence or absence of a magnetic field is used for tamper evidence purposes. In addition, this can also function as a configuration switch for determining the time for the communication of the measured values to the remote readout device. The data are transmitted via radio link to a remote readout device, which collates them. Mirakonta had previously used a reed switch as a water flow meter, but this didn't always deliver precise consumption values. A new sensor model would not only need to determine more accurate values, but also meet the increasing demands on energy efficiency. For support with this task, the manufacturer turned to Rutronik. 30

Mirakonta has already been working closely with the distributor for five years. “In the past, we would have chosen a magnet sensor with low energy requirements for this type of application,” explained Thomas Kepcija, Product Sales Manager Sensors at Rutronik. “This time, however, Mirakonta’s requirements on the energy consumption were so strict that those models simply couldn’t comply with them. As such, the new development from Honeywell Sensing and Control came at just the right time.” The sensor specialist launched the industry’s first anisotropic magneto-resistive (AMR) nanopower sensor. With an energy consumption in the nano range (360 nA) and high sensitivity of typically just 7 Gauss, it satisfies both criteria.
Durable and ultrasensitive Compared with other magnetic technologies, magneto-resistive sensor ICs offer a number of advantages: They are smaller, more durable, and more reliable than reed switches, but still offer the same sensitivity and are in the same price range. As such, they are ideal for battery-powered applications, which function with a very low energy consumption and a large air gap, and for which it was only possible to use reed switches up until now. Compared with Hall-effect sensors, the increased sensitivity of the nanopower sensor ICs of typically 7 Gauss and maximum 11 Gauss makes it possible to use them with an air gap twice as large. “In addition, they take up less space and reduce costs, as smaller, weaker magnets can be used. Engineers are also afforded more design flexibility, as, thanks to the extreme sensitivity, they can work with higher tolerances when it comes to the magnetic activation of the sensor,” summed up Thomas Kepcija. Rutronik provided Mirakonta with detailed technical data and sent sample items within just a few days for testing of the new sensor. The tests showed: the new sensor mastered all the challenges with flying colors. This positive result paved the way for developing the new water meter. Nicolas Roche, the product manager at Honeywell, is convinced that the nanopower range will give Mirakonta a new impulse, “In Mirakonta’s case, this improves the monitoring while reducing the energy consumption and ultimately the costs. In addition, the life span of the battery corresponds to that of the sensor and it was possible to eliminate the shortfalls of older technologies like the failure or gradual loss of stability of the switches. All this makes the sensor a ￭ game-changing, sustainable product.” Rutronik www.rutronik.com www.epd-ee.eu |

PRODUCT NEWS Power Integrations Simplifies Design of Industrial PSUs for 440VAC Line Input Power Integrations announced a new reference design (DER-479) demonstrating an industrial power supply using the company’s LinkSwitch4TM family of CV/CC primary-side regulated (PSR) switcher ICs with a 1200 V bipolar junction transistor (BJT). The design supports 440 VAC line inputs and features three outputs which combine to provide up to 11 W of highly accurate constantvoltage DC power.
LinkSwitch-4 controllers feature an adaptive base and emitter switched drive scheme to boost switching performance and increase efficiency. The advanced switching technique is especially beneficial in high-voltage applications as it reduces slow turn-off switching losses and eliminates BJT failures due to secondary breakdown, improving the reverse-bias safe operating area (RBSOA) and system reliability. Additionally, the LinkSwitch-4 controller’s primary-side regulated sensing methodology eliminates expensive and unreliable optocouplers, replacing them in the feedback loop with a simple transformer winding. The design uses just 50 mW under no-load conditions while maintaining a fast transient response. The 65 kHz operating frequency minimizes transformer size, reducing system cost and PCB footprint. LinkSwitch-4 devices also compensate for a number of factors including: transformer inductance tolerances; input line voltage variations; cable voltage drop; and external component temperature variations. Comments Silvestro Fimiani, senior product marketing manager at Power Integrations: “Power supplies for high-voltage systems such as three-phase meters and motor drives can be challenging to develop – efficiency, reliability and component count often suffer in such designs. By pairing the LinkSwitch-4 controller with a 1200 V BJT, the designs become very straightforward and extremely reliable.” POWER INTEGRATIONS www.power.com 38

ACTIVE COMPONENTS Toshiba Introduces New Four Pin TO-247 Package for DTMOS IV-H Power MOSFETs Toshiba Electronics Europe has introduced a new four pin TO-247 MOSFET package targeting power factor control for high power Smart Power Stage (SPS). The new package is equipped with high speed DTMOS-H chips with low QGD to optimise switching behaviour. In conventional three pin TO247 packages, parasitic induction at the source pin causes increased losses with increasing switching frequency. With the new TO-247 4L package an additional source signal terminal is separated as a ‘Kelvin source’. By using this source pin, di/dt and switching efficiency can be increased. Compared to a three pin solution, the switching loss E(on) will be reduced by the new four pin solution by about 15%. The DTMOS IV-H chips are made using Toshiba’s Deep Trench technology that delivers
lower ON resistance (RDS(ON)) at higher temperatures, compared to conventional super junction MOSFETs. It also offers reduced turn-off switching losses (EOSS) than previous technology generations. The combination of
smaller increases in RDS(ON) at high temperatures and reduced EOSS provides higher efficiency for power supplies and assists designers in minimising system size. TOSHIBA ELECTRONICS EUROPE www.toshiba.semicon-storage.com
