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.
