32-bit FR Family

FR Family Features

• CPU core capable of running at a peak rate of 64 VAX MIPS (CPU core performance) at 50 MHz while featuring

its compactness equivalent to 16-bit microcontrollers

• 5-stage pipelining and harvard-bus architecture, allowing efficient execution

• Implementation of, basically, 16-bit fixed length commands, providing high object code efficiency

• The command group enhanced for controllers and an algorithm engine, resulting in faster execution of instruc-

tions

• A variety of resources including the sum-of-product units

• Many kinds of internal peripheral devices
