1.1
Overview
Features
The M32C/8B Group is a single-chip control MCU, fabricated using high-performance silicon gate CMOS
technology, embedding the M32C/80 Series CPU core. The M32C/8B Group is housed in 144-pin and 100-pin
plastic molded LQFP packages.
With a 16-Mbyte address space, this MCU combines advanced instruction manipulation capabilities to process
complex instructions by less bytes and execute instructions at higher speed.
The M32C/8B Group has a multiplier and DMAC adequate for office automation, communication devices and
industrial equipment, and other high-speed processing applications.
