DESCRIPTION

The FR family is a line of microcontrollers based on a 32-bit RISC CPU that contains a variety of built-in I/O resources for embedded control application which require high-performance, high-speed CPU processing.

The MB91605 series of microcontrollers are based on the FR80 family and offer enhanced bus access that is optimal for embedded applications for controlling DVD players, printers, TVs, and PDPs.
