M16C / 62M (80-pin version) Group
(Low voltage version)
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
The M16C/62M (80-pin version) group (low voltage version) 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 execut-
ing 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/62M (80-pin version) group (low voltage version) includes a wide range of products with different
internal memory types and sizes and various package types.
