M32C81
M32C81 is SINGLE-CHIP 16/32-BIT CMOS MICROCOMPUTER manufactured by Renesas.
Overview
The M32C/81 group microputer 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 100pin plastic molded LQFP/QFP packages. With a 16-Mbyte address space, this microputer bines advanced instruction manipulation capabilities to process plex instructions by less bytes and execute instructions at higher speed. It incorporates a multiplier and DMAC adequate for office automation, munication devices and industrial equipments and other high-speed processing applications.
1.1 Applications
Audio, cameras, office equipment, munications equipment, portable equipment, etc.

1. Overview
1.2 Difference between the M32C/81 Group and the M32C/83 Group
The M32/C81 group microputer has less peripheral functions than the M32C/83 group miccroputer. The intelligent I/O group 3 and the A/D1 converter are not provided in the M32C/81 group. Interrupt requests, and as a result interrupts, DMAC, and DMACII, caused by intelligent I/O group 3 are not available in the M32C/81 group. However, the A/D1 conversion interrupt is generated in place of the A/D0 conversion interrupt when input voltage applied to AN00 to AN07, AN20 to AN27, AN150 to AN157 pins are converted.
