------Table of Contents------
Description
The M16C/62 (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/62 (80-pin version) group includes a wide range of products with different internal memory types
and sizes and various package types.
