MCU Targets Ultra-Low-Power Apps

    Featuring 256 bytes of RAM, the 16-bit MSP430F42x0 series microcontrollers (MCUs) from Texas Instruments typically draw 1.1 uA in real-time clock standby mode and 300 uA in active mode. Flash programming of the 32-kbyte memory only requires 2.5 V, making it ideal for battery operation in devices like altimeters and portable instrumentation. The chip incorporates an LCD interface and charge pump to minimize the system's bill of materials. Other peripherals include a five-channel, 15-bit analog-to-digital converter (ADC) with a programmable gain, a 12-bit digital-to-analog converter (DAC) with a 1-µs settling time, 32 GPIO, and an on-chip oscillator. Pricing starts at $2.95.

    I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.  

    I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
