SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
Description
The M16C/80 (144-pin version) group 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 144-pin plastic
molded QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high
level of instruction 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.
The M16C/80 (144-pin version) group includes a wide range of products with different internal memory
types and sizes and various package types.
