Description
MITSUBISHI MICROCOMPUTERS
M30222 Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
The M30222 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 and
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 pro-
cessing applications.
The M30222 group includes a range of products with various package types.
