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.
