Texas Instruments Incorporated announced its new C2000™ Concerto dual-core microcontroller (MCU) series. The new Concerto 32-bit microcontrollers combine TI’s class-leading-performance C28x core and control peripherals with an ARM Cortex-M3 core and connectivity peripherals to deliver a clearly partitioned architecture that supports real-time control and advanced connectivity in a single, cost-efficient device. To make them easy to use, Concerto MCUs are supported by an intuitive software infrastructure as well as application and connectivity libraries within controlSUITE™ software. The series includes multiple safety and security features and is code compatible across the C2000 platform to enable scalability and code reuse in green applications such as intelligent motor control, renewable energy, smart grid, digital power and electric vehicles.
Greener applications require the performance of a real-time control MCU to execute complex algorithms needed for precise, efficient power conversion, which is the essence of efficient motor control, renewable energy and smart grid technologies. But to take that efficiency to new levels that can dramatically save energy, these applications must also be connected for remote data sharing, diagnostics, monitoring and control. Concerto MCUs enable developers to do both real-time control and connectivity within one microcontroller, eliminating the traditional need to choose between optimal performance and advanced connectivity.
Concerto F28M35x microcontroller series features and benefits:
- Real-time control subsystem based on TI’s C28x core with floating point and the Viterbi Complex Math Unit delivers 13X performance over existing MCUs as well as industry-leading control peripherals required to design the most reliable, efficient green applications
- Robust host communication subsystem based on Cortex-M3 and connectivity peripherals such as Ethernet, USB On-The-Go, dual CAN, and multiple serial communication ports
- Performance can be tailored to different applications with options for 150/75 MHz, 100/100 MHz or 60/60 MHz on the C28x and Cortex-M3 cores, respectively
- Safety and security features, including up to 1 MB of flash and 132 KB RAM with error correction, parity on CAN and interrupt registers, redundancy for functions, and lock protection
- Free turnkey application and connectivity software libraries, including Ethernet and USB (Digital power, motor control and renewable energy libraries will be available in 3Q11)
- Speeds design with simple development environment that supports programming each subsystem independently
- Roadmap for tailored devices to meet specific smart grid applications, such as smart electric meters and concentrators
The new Concerto F28M35x Experimenter Kit includes a F28M35x controlCARD and docking station to enable developers to easily begin evaluation and development. The modular controlCARD is hardware compatible with TI’s C2000 application-specific development kits, and software to further support development on the kits will be available later this year. Free, on-demand training for Concerto MCUs is immediately available online, and is a great way for developers to begin further exploring the optimized architecture, tailored features and easy-to-use software infrastructure of the devices.
Available in a 144 QFP package, Concerto MCUs now start at $6.99 at 1K and samples can be immediately ordered at www.ti.com/concerto-es-lp-pr. The Concerto F28M35x Experimenter Kit is priced at $139.

Samsung has been taunting us with the promise of 30nm DRAM for quite sometime, and when the tiny chips went into mass production last year it was the world's servers that got first dibs. The average consumer stuck with that aging 40nm stuff -- blech. This summer though, you'll finally be able to snatch up some of Sammy's latest tech in the form of two and four GB DDR3 1600 sticks for both laptops and desktops. The company claims that its new RAM modules are up to two-thirds more energy efficient than more common 60nm chips and 20 percent faster that its own 40nm ones. Both solo and dual packs will be hitting retailers soon starting at "less than $30." Check out the PR after the break.

ADIS16407 iSensor IMU Functional Block Diagram(Photo from Analog Devices Website)
Analog Devices released the ADIS16407 iSensor® IMU (inertial measurement unit) which integrates a tri-axis gyroscope, tri-axis accelerometer, tri-axis magnetometer and a pressure sensor into a single package. Each sensor in the ADIS16407 combines ADI’s industry-leading iMEMS® technology and signal conditioning expertise to optimize the IMU’s 10- DoF (degrees-of-freedom) dynamic performance. Every IMU is factory calibrated for sensitivity, bias, alignment, and temperature. As a result, each sensor has its own dynamic compensation formulas, maximizing accuracy of sensor measurements.
“Emergency first responders, unmanned vehicles, and precision autonomous instruments often require the merging of multiple sensors to accurately track location in office buildings, warehouses, tunnels, caves, mines, ‘urban canyons’ and other GPS-denied environments,” said Bob Scannell, iSensor business development manager, MEMS/Sensors Technology Group, Analog Devices. “All existing 10-DoF IMUs for these applications are significantly larger, with less factory calibration, and do not adequately address the price-performance requirements. The ADIS16407 combines all of these sensors in a single package, fully integrated and calibrated at the factory, at a low system price.”
ADIS16407 Inertial Measurement Unit Key Features
- High performance triaxial, digital iMEMS gyroscope with digital range scaling: ±75°/sec, ±150°/sec, ±300°/sec settings
- High performance triaxial, digital ±18 g iMEMS accelerometer
- Triaxial ±2.5 gauss digital magnetometer
- Digital pressure sensor rated at 10 mbar to 1200 mbar
- All sensors aligned and calibrated at the factory
Full Production : Now
Price per 1 k Units : $444.00

Skyworks Solutions introduced the first in a series of ultra low current, general purpose low noise amplifiers (LNAs) for diverse wireless applications including satellite receiver set-top boxes, Bluetooth® headsets, medically prescribed hearing aids, advanced meter reading devices and 2.4 GHz wireless local area networks. These high performance LNAs deliver enhanced receiver sensitivity and wide dynamic ranges facilitating improved signal reception, increased design flexibility and reduced part counts
The miniature SKY67014-396LF is an advanced gallium arsenide pseudomorphic high electron mobility transistor (pHEMT) enhancement mode process LNA with an integrated active bias and on-die stability structures enabling simple external matching and stable performance over temperature. Skyworks’ enhancement mode pHEMT process allows the device to offer excellent return loss (15 dB typical), stable gain (12 db), low noise (<1 dB) and high linearity (+18 dBm OIP3) while drawing <6 ma of bias current. The SKY67014-396LF offers the designer the ability to externally adjust the supply current to further optimize the amplifier linearity performance for the chosen application. The supply voltage is applied to the RF-OUT/VDD pin through an RF choke inductor and through the VBIAS pin through an external resistor. The supply voltage is adjustable over a range of 1.5 to 5V. The LNA is manufactured in a compact, 2 x 2 millimeter, 8-pin dual flat no-lead, restriction of hazardous substances compliant, surface mount technology package.
The device is the first in a series of high performance, low power LNAs targeting broadband wireless applications. Additional footprint compatible LNAs for the 100 – 700 MHz and 700 – 1500 MHz bands will be launched later this year.

interactive pool tables and digitally assisted billiards, but isn't it time we completely outsourced our pool-playing to brutally efficient robots? The Germans obviously think so, using this year's International Conference on Robotics and Automation to debut a dual-armed poolbot able to make "easier" shots about 80 percent of the time. Those misses sound a bit like hustling to us, and unlike Willow Garage's friendly PR2 robot, the German version has a suitably intimidating, industrial look. It's also a bit of a cheat, using an overhead camera to plan its shots. For the full lowdown on this shark, check the video after the break.

If you haven't already heard, wireless charging is all the rage -- cars, cameras, and, of course, cellphones have all benefited from the burgeoning technology. Now a team of researchers at Japan's National Institute of Information and Communications Technology (NICT) are showing off a 2D power transmission system that could turn your pockets into wireless charging stations. According to its creators, "When a 2.4GHz high frequency signal is transmitted through the sheet, it becomes a wireless conductive object." Electromagnetic waves are captured in the sheet and can be concentrated in particular areas, allowing for individual activation of multiple devices, and thus increasing efficiency -- systems like Qi currently require a dedicated transmitter per device. The NICT says the power it provides is still relatively weak -- about 1W -- but it has plans to eventually bring the technology to soft fabrics. So maybe that Snuggie charging station you've been dreaming of isn't so impractical after all.
