SINGLE-CHIP 16/32-BIT CMOS MICROCOMPUTER
REJ03B0031-0020Z Rev.0.20 1 Jul., 2003
1. Overview
The M32C/81 is single-chip microcomputer that utilizes high-performance silicon gate CMOS technology with the M32C/80 series CPU core. The M32C/81 group is available in the 144-pin and 100-pin plastic molded QFP/LQFP package. With 16-Mbyte address space, this microcomputer combines advanced instructions manipulation capabilities to process complex instructions by less bytes and execute instructions at higher speed. It incorporates a multiplier and DMAC adequate to 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.

1. Overview
1.2 Difference between the M32C/81 Group and the M32C/83 Group
T h e M32/C81 group microcomputer has less peripheral functions than the M32C/83 group miccrocomputer. The intelligent I/O group 3 and the A-D1 converter are not provided in the M32C/81 group. Consequently, interrupts caused the intelligent I/O group 3 interrrupt request, a DMAC operation with the intelligent I/O group 3 and a DMACII operation with the intelligent I/O group 3 are not available in the M32C/81 group.
