SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
About M32C/83 Group
The M32C/83 group of single-chip microcomputers are built using a high-performance silicon gate CMOS
process uses a M32C/80 Series CPU core and are packaged in a 144-pin and 100-pin plastic molded QFP.
These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruc-
tion 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.
Applications
Audio, cameras, office equipment, communications equipment, portable equipment, etc.
