Jul. 01, 2005
1. Overview
The M32C/85 group (M32C/85, M32C/85T) microcomputer is a single-chip control unit that utilizes high-
performance silicon gate CMOS technology with the M32C/80 series CPU core. The M32C/85 group
(M32C/85, M32C/85T) 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 includes a multiplier and DMAC adequate for office automation, communication devices and industrial
equipments, and other high-speed processing applications.
1.1 Applications
Automobiles, audio, cameras, office equipment, communications equipment, portable equipment, etc.
