The Z16FMC Series of Motor Control MCUs features Zilog’s ZNEO® CPU, which boasts a highly-optimized instruction set that achieves higher performance per clock cycle with less code space and lower overhead than competing architectures.
The Z16FMC6 MCU is a 16-bit single-cycle CISC device with 64K of internal Flash memory and is designed for the control of multiphase AC and DC variable-speed motors.
Target applications are large appliances, HVAC and industrial. If you're building a stepper motor, consider Zilog's Z8F1680 MCU, your best-bet low-power solution.
