1. Overview
1.1 Features
The M16C/5M and M16C/57 Group’s microcomputers (MCUs) are single-chip control units that utilize high-performance silicon gate CMOS technology with the M16C/60 Series CPU core. The M16C/5M Group and M16C/57 Group are available in 64-pin, 80-pin, and 100-pin plastic molded LQFP packages. The MCUs employ sophisticated instructions for a high level of efficiency and they are capable of executing instructions at high speed. The MCUs have the CAN module (M16C/5M Group) and LIN module, which makes them suitable for automotive control and factory automation LAN systems. In addition, the CPU core boasts a multiplier and DMAC for high-speed operation processing which makes it adequate for controlling office equipment, home appliances, and industrial equipment. The M16C/5M and M16C/57 Group’s MCUs are a high-end microcontroller series in the M16C/5L and M16C/56 Group, featuring a single architecture as well as compatible pin assignments and peripheral functions. They have an on-chip E2PROM emulation data flash (E2dataFlash) which is a data flash with serial E2PROM.
