SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

Description

------Table of Contents------

Description

The M16C/62A (80-pin version) group of single-chip microcomputers are built using the high-performance

silicon gate CMOS process using a M16C/60 Series CPU core and are packaged in a 80-pin plastic molded

QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high level of

instruction efficiency. With 1M bytes of address space, they are capable of executing instructions at high

speed. They also feature a built-in multiplier and DMAC, making them ideal for controlling office, communi-

cations, industrial equipment, and other high-speed processing applications.

The M16C/62A (80-pin version) group includes a wide range of products with different internal memory

types and sizes and various package types.
