Overview

The M16C/80 group of single-chip microcomputers are built using the high-performance silicon gate CMOS process using a M16C/80 Series CPU core and are packaged in a 100-pin and 144-pin plastic molded QFP. The peripheral functions of 100-pin and 144-pin are common. 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.
