Optimized for motor control and smart sensing applications, Analog Devices ADuC7128 microcontroller (MCU) integrates a 32-bit ARM7 RISC processor with high-speed, multi-channel data conversion, and 126 kbytes Flash memory. The unit's 12-bit multi-channel, analog-to-digital converter (ADC) operates at speeds to 1 MSPS (mega-samples-per-second). Motor control specific peripherals include six-channel pulse-width modulation (PWM) with H-bridge mode. An on-chip quadrature encoder provides the speed, position, and direction control required by dc motor controls. In addition, the ADuC7128 has an integrated direct digital synthesizer (DDS), and I/V control making it applicable to a variety of motor control applications. Packaged in a 9 × 9 mm 64-LFCSP (lead-frame chip-scale package), the device is specified over an operating temperature range of -40 to +85C.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
The US Congress has extended an important tax credit for solar energy, a move that’s good news for future investments in this type of alternative energy and for many stakeholders in the solar industry.
