The 56F8000 targets a range of motor control and system control applications. Developed by Freescale, this chip keeps monetary and power costs low while delivering advanced peripheral control.

The pulse-width modulators (PWMs) operate at three times the clock frequency. Each pair can generate differential switch frequencies. The application has cycle-by-cycle control over the PWMs, which also have multiple programmable fault ports and can operate while the CPU is sleeping.

The 12-bit analog-to-digital converter can support two conversions at a time. Pricing starts at $2.99.

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.
