ST Introduces World’s Smallest 3-Axis Gyroscope

Cuts package size by almost a factor of 2 to open up new designs
By Nick Flaherty www.flaherty.co.uk

ST has shrunk its popular 3-axis analogue gyroscope by half.
The L3G3250A combines the same robust and field-proven micromachined MEMs technology that ST has already used to produce nearly 1.54 billion motion sensors with a smaller package technology to make it the first 3-axis gyroscope to meet the demand for smaller footprints in next-generation applications such as gaming and virtual reality input devices, motion control for MMI (man-machine interfaces), GPS navigation systems, and appliances and robotics.
The sensor is a high-performance three-axis analogue-output gyroscope housed in a package measuring just 3.5x3x1 mm, reducing the footprint from 17.6 mm3 - the current generation in production today - to just 10.5 mm3, a reduction of nearly 40%. 

With a resonant frequency beyond the audio bandwidth, the L3G3250A is completely immune to audio noise, such as from speakers mounted close to the sensor, and mechanical vibrations coupled through the printed circuit board, therefore operating with greater accuracy and reliability. In addition, its design of a single sensing structure for motion measurement along all three orthogonal axes further increases sensing accuracy and reliability and delivers the industry’s highest level of output stability over time and temperature. The combination of high sensing resolution with outstanding immunity to audio noise and vibrations makes motion-sensing user interfaces more realistic in mobile phones, tablets, game consoles, and other smart consumer devices.
The L3G3250A offers two user-selectable full scales – 625 or 2500 dps (degrees per second) – with sensitivities of 2mV/dps and 0.5mV/dps, respectively. The high range allows the device to detect and measure very fast gestures and movements. Other features include an embedded self-test function, a wide supply voltage range (2.4 V to 3.6 V), embedded power-down and sleep modes to optimize power management in battery-operated devices, an embedded low pass filter and a high pass filter reset function, and high shock survivability.
The device operates over an extended temperature range (-40°C to 85°C) and is available in a 3.5x3x1 mm3 LGA-16 ECOPACK RoHS compliant package. Engineering samples are available now and volume production is scheduled for Q4 2011, with unit pricing at $3.95 for volumes in the range of 1,000 pieces.

MathWorks move model-based design into SoCs with Faraday

MATLAB and Simulink Speed Simulations by 200x and Reduce Gate Count by Half
By Nick Flaherty www.flaherty.co.uk


MathWorks is succcessfully moving its MATLAB and Simulink model-based deign tools more into silicon design. Faraday Technology is using Model-Based Design to accelerate the development of SoCs, including development of its NAND Flash Controller error correcting code (ECC) engine. MATLAB and Simulink have helped Faraday accelerate development of more efficient designs by completing system-level simulations 200 times faster, increasing throughput performance by 15%, and cutting gate count by up to 57%.
Stateflow chart of the error correcting code (ECC) engine for Faraday’s NAND flash controller.
Faraday is using this to capitalise on the move to advanced SoC designs. To meet this demand, Faraday established a faster and more cost-efficient workflow to develop memory controllers for microprocessor subsystems. Faraday adopted Model-Based Design to accelerate SIP development, explore system-level design alternatives, and improve communication among engineers. This design approach has helped reduce gate count, and shorten the development cycle for memory controllers and other modules, and, as a result, differentiate itself through lower cost to its customers.
“Model-Based Design provided an efficient and cost-effective way to improve silicon intellectual property development by enabling us to rapidly identify the best design configurations and get products to market faster,” said Ken Chen, ESL Methodology Manager at Faraday. “The Simulink environment is ideal for integrating, simulating, and exploring design architectures. The simulations are up to 200 times faster than RTL simulations, and Simulink models can be easily converted to HDL code for FPGA prototyping.”
Optimising the gate count of the ECC block

Faraday engineers used MATLAB, Simulink, and Stateflow to model and simulate their system-level designs, and used Simulink Coder and Simulink HDL Coder to automatically generate code from their models. This workflow enabled Faraday to shorten their design process as they moved from architecture design to hardware and software implementation. Faraday has used Model-Based Design for DDR and flash controller projects and delivered the SIP designs on schedule. The engineering team is now focused on further accelerating development by reusing and adapting their existing models on new projects.
“As integrated circuit manufacturers continue to rely on SIP providers for SoC and ASIC components, SIP engineers need the ability to rapidly deliver designs that meet their customers’ requirements,” said Ken Karnofsky, senior strategist for signal processing applications, MathWorks. “Faraday’s use of MATLAB and Simulink showcases the effective use of Model-Based Design to accelerate development, reduce costs, and simplify the integration of SIP modules into SoC designs.”

Zigbee gains early lead in $12bn smart grid market

By Nick Flaherty www.flaherty.co.uk

Revenues over $12bn by 2016 with powerline dominating but US rollouts peak this year
Worldwide smart meter revenues will grow to over $12bn by 2016, with the vast majority ZigBee-enabled say market researchers In-Stat..
The smart meter is a device that is at the heart of the smart grid transformation. It records a user’s electrical, water, or gas usage at a set interval, and then provides a way for this data, or a subset of this data, to be read electronically, but that is just its minimum function.
“ZigBee has been considered the front-running short range connectivity option for smart grid since its inception, and has maintained its position so far. While the number of ZigBee clients in homes to date is relatively small, In-Stat believes that ZigBee will maintain its dominance,” says Allen Nogee, Research Director. “Although Wi-Fi is pervasive, it has not been a viable choice for the smart grid because the application layers have never existed for Wi-Fi that explain exactly how Wi-Fi devices interact. That will all change with the passage of the IP-based Smart Energy Profile 2.0, expected late in 2012.”

Recent In-Stat research found:
  • Powerline is the clear leader in backhaul connectivity from the meter to the utility. However, we are seeing an increasing number of wireless solutions including cellular, white space, and proprietary methods that would use unlicensed and operate in mesh configuration. 
  • China, the world’s biggest energy consumer, is also the biggest smart meter consumer.
  • The number of smart meters deployed in the US per year will decrease after peaking in 2011, but worldwide smart meter deployment will continue to grow.

Recent In-Stat research Getting Smart on Worldwide Smart Meter Communication Technology(#IN1104731WH) contains an in-depth look at the smart grid in general, and the smart meter and communication technology employed and includes:

New SATA µSSD Specification for Embedded Solid State Drives

By Nick Flaherty www.flaherty.co.uk

Connector-free, high-capacity, embedded SSDs for a new generation of tablets and ultrathin notebooks

Memory maker SanDisk has implemented the new SATA µSSD specification into its SanDisk iSSD product line of postage stamp-sized embedded SSDs. SATA-IO, an industry consortium dedicated to sustaining the quality, integrity and dissemination of serial ATA (SATA) technology, introduced the standard today.
The number of media tablets shipped worldwide is expected to grow from 17.8 million units in 2010 to 53.5 million units in 2011 according to IDC.
The Serial ATA International Organization (SATA-IO) is also developing SATA Express, a new specification that combines SATA software infrastructure with the PCI Express (PCIe) interface. SATA Express enables the development of new devices that use the PCIe interface and maintain compatibility with existing SATA applications. The technology will provide a cost-effective means to increase device interface speeds to 8Gb/s and 16Gb/s.
Embedded SSDs offer fast performance in a tiny footprint, making them an attractive solution for all categories of ultrathin devices. The SATA µSSD specification (see below) eliminates the module connector from the traditional SATA interface, enabling developers to produce a single-chip SATA implementation for embedded storage applications. Among the first products to implement the new standard, the SanDisk iSSD series is an ideal storage solution for OEMs developing the next generation of thin, powerful mobile computing platforms.
“To widely adopt a new component technology, manufacturers need to have confidence in its performance, longevity and cost-effectiveness,” said Jeff Janukowicz, research manager, solid state storage technology at IDC. “Today’s announcement of an industry-wide standardization for embedded SSDs, combined with OEM requirements for size and performance gains in storage, should help propel the market for these tiny, versatile drives.”
“Connector-free embedded SSDs allow OEMs to develop a new generation of thin yet powerful tablets and ultrathin notebooks,” said Kevin Conley, senior vice president, client storage solutions, SanDisk. “Initiatives such as the µSSD specification promote the development of new standards for storage solutions that help manufacturers continually refine their end consumer product and drive new industry sectors.”
The SATA µSSD standard-conforming SanDisk iSSD series utilizes a new electrical pin-out that allows SATA delivery using a single ball grid array (BGA) package. The BGA package sits directly on the motherboard, allowing for form factors as small as 16mm x 20mm x 1.2mm (up to 32GB)/1.4mm (for 64GB) and 16mm x 20mm x 1.85mm (for 128GB). The SanDisk iSSD i100 SSD is available in 8 gigabyte (GB)1 to 128GB capacities, offering OEMs a flexible range of storage options.
“The market for tablets and ultrathin computing devices continues to grow along with the need for small form factor storage solutions,” said Mladen Luksic, president, SATA-IO. “We are excited to have industry-wide support for the µSSD specification and look forward to seeing many µSSD-based products available in the near future.”
SATA Express will provide a low-cost solution to fully use the performance of SSDs, while storage devices not requiring the speed of SATA Express will continue to be served by existing SATA technology. The specification will define new device and motherboard connectors that will support both new SATA Express and current SATA devices.
“The SATA Express specification provides SSD and hybrid drive manufacturers the advantages of performance and scalability enabled by PCIe 3.0 – which is available now – and the ubiquity of SATA,” said Mladen Luksic, SATA-IO president. “We expect the SATA Express specification to be completed by the end of 2011.”

The Complete SATA Ecosystem
SATA Express is one of several specifications from SATA-IO designed to offer low-cost, high performance storage solutions optimized for specific device segments. Since its introduction in 2001, SATA technology has penetrated 99% of the PC market and evolved to provide options for a number of applications beyond traditional hard disk storage. SATA is now implemented in a variety of applications including solid state and optical drives, embedded mobile devices, consumer electronics products and enterprise storage. Key specifications for implementing SATA technology beyond the HDD device segment include:
  • mSATA: A low-profile solution for mobile computing devices and other small form factor applications.
  • SATA Universal Storage Module (USM): An integrated SATA interface for providing portable, volume storage I/O to consumer electronics devices, as well as PC applications.
  • SATA µSSD: an embedded, single-chip solution that connects directly to the motherboard to enable ultra-thin form factor devices.
More information on these and other SATA specifications is available at www.sata-io.org.

By Nick Flaherty www.flaherty.co.uk

Panasonic, Samsung Electronics, Sony and X6D (XPAND 3D) are to collaborate on the development of a new technology standard for consumer 3D active glasses called the "Full HD 3D Glasses Initiative."
The companies say they will work together on the development and licensing of radio frequency (RF) system 3D active glasses technology, including RF system protocols between consumer 3D active glasses and 3D displays such as televisions, personal computers, projectors and 3D theatres with XPAND active shutter glasses.
These glasses end a full HD image to each eye to give higher quality 3D but there are different standards, limiting the uptake by consumers.
The standardization will also include multiple types of infrared (IR) system protocols between 3D active glasses and 3D displays, ranging from the protocols jointly developed by Panasonic and XPAND 3D to the proprietary protocols of Samsung and Sony.
The licensing is targeted to be released in September 2011 and then the development of the new standard 3D glasses will begin. Universal glasses with the new IR/RF protocols will be made available in 2012, and are targeted to be backward compatible with existing systems.
"Panasonic has been working to standardize 3D glasses technologies, and in March, we announced a joint licensing of IR system protocols with XPAND, backed by several participant companies. We are very pleased that today's latest collaboration will incorporate our previous concept into these new standardization efforts," said Masayuki Kozuka, general manager of Media & Content Alliance Office, Corporate R&D Division, Panasonic Corporation. "We hope the expanded collaboration on this 3D standardization initiative will make a significant contribution toward accelerating the growth of 3D-related products."
"Today's announced collaboration underscores Samsung's promise to meet consumer needs among the ever-changing advancements of home entertainment and consumer electronics technology," said Jurack Chae, vice president, R&D Team, Visual Display Business, Samsung Electronics. "To-date, active 3D technology has proven to be the most popular choice for consumers in the 3D TV market. According to the NPD Group, Active 3D technology took an average of 96 percent share of the U.S. 3D TV market in the first half of this year; and this Full HD 3D Glasses Initiative will help further drive consumer adoption and understanding of active 3D—the technology that provides the clearest and most immersive 3D experience available."
"Through this alliance, we all look forward to addressing critical industry issues to enable a better consumer experience across products. We believe active 3D technology is the most suitable method to deliver full 1080p picture quality to each eye, giving consumers the 3D experience they most desire," said Jun Yonemitsu, deputy senior general manager, Home Entertainment Development Div., Sony Corporation.
"We are delighted to contribute our efforts and technologies to the Full HD 3D Glasses Initiative for both RF and IR technology that we announced today with Panasonic, Samsung and Sony. This initiative reinforces the consumer electronics industry's commitment to highest 3D quality and provides technology consumers and theater-goers with a simple but powerful solution to the challenge of interoperability," said Maria Costeira, XPAND 3D's CEO.
The Bluetooth SIG supports the industry's move to standardize on Bluetooth technology in 3D glasses.
"These market leaders are coming together to make the 3D experience better for the consumer. It makes perfect sense thatBluetooth technology would be a vital component of that solution, both for its mass market ubiquity and the freedom and convenience it provides," said Dr Michael Foley, executive director, Bluetooth SIG. "And while today's news is exciting, this is just the beginning—Bluetooth technology in the living room makes sense in 3D glasses, stereo surround systems, remote controls, and ultimately the hub of the living room—the TV."

The protocols jointly developed by Panasonic and XPAND were announced in March 2011 and supported by eight participant companies: Changhong Electric, FUNAI Electric, Hisense Electric, Hitachi Consumer Electronics, Mitsubishi Electric, Seiko Epson, SIM2 Multimedia and ViewSonic.

Source Code of Popular Real-Time Kernel Now Available for Free Evaluation

By Nick Flaherty www.flaherty.co.uk

Embedded real time operating system vendor Micrium is to make the source code of the popular real-time kernel uC/OS-III available free of charge to developers who wish to evaluate uC/OS-III, as can researchers, students and others in academia.
To help ensure that developers who try out uC/OS-III will be able to make the most of the experience, Micrium is also making PDFs of the book uC/OS-III, The Real-Time Kernel available for free download. Several versions of this book, each tailored to a different embedded platform, are now available in both print and free PDF editions.
"Together, the uC/OS-III kernel and book provide practically everything needed to get started writing powerful, multitask applications," said Jean Labrosse, founder and CEO of Micrium. "Now these essential tools can be downloaded by busy developers in just a matter of minutes."
For years, developers interested in evaluating uC/OS-II have been able to download its source code directly from Micrium's Web site. Now, the same model is being applied to uC/OS-III.
Under the source-available model, the path from evaluation to production is simple and well defined. Developers begin the evaluation process by downloading source code from the Micrium Web site. Once they've decided to use uC/OS-II or uC/OS-III to develop a product, they must purchase a license for the software from either Micrium or an authorized distributor.
"The source-available model combines the best of the commercial and open-source RTOS worlds, giving embedded systems developers software that is meticulously maintained and supported, yet is remarkably easy to evaluate," said Labrosse. "Micrium's move to make uC/OS-III source available is a reflection of our keen interest in helping developers to overcome the challenges that they confront on a regular basis."
The uC/OS-III source code can be downloaded from http://micrium.com/downloads/. Developers who have already completed a successful evaluation of uC/OS-III and are planning to use the kernel in a product can contact Micrium's sales team for licensing.
