SINGLE-CHIP 16/32-BIT CMOS MICROCOMPUTER
REJ03B0031-0100Z
Rev.1.00
Jun. 01, 2004
1. Overview
The M32C/81 group microcomputer is a single-chip control unit that utilizes high-performance silicon gate
CMOS technology with the M32C/80 series CPU core. The M32C/81 group is available in 144-pin and 100-
pin plastic molded LQFP/QFP packages.
With a 16-Mbyte address space, this microcomputer combines advanced instruction manipulation capabili-
ties to process complex instructions by less bytes and execute instructions at higher speed.
It incorporates a multiplier and DMAC adequate for office automation, communication devices and industrial
equipments and other high-speed processing applications.
1.1 Applications
Audio, cameras, office equipment, communications equipment, portable equipment, etc.
