(100-pin version) group

16-BIT CMOS MICROCOMPUTER

Description

The M16C/80 (100-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 100-pin plastic

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

level of instruction efficiency. With 16M 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,

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

The M16C/80 (100-pin version) group includes a wide range of products with different internal memory

types and sizes and various package types.
