■ OVERVIEW

MB91220/S series is a line of single-chip microcontrollers based on a 32-bit high-performance RISC CPU and integrating a variety of I/O resources for embedded control applications.

The MB91220/S series is designed to be best suited for embedded applications which require high-speed and high-performance processing power in the CPU, such as DVD players, printers, TV sets, and the PDP control.The MB91220/S series is a line of CPUs in the FR60Lite implemented by FR* family.
