Description

The M16C/62N (80-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 80-pin plastic molded QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruction efficiency. With 1M bytes of address space, low voltage (2.4V(mask ROM version is 2.2V) to 3.6V), 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/62N (80-pin version) group includes a wide range of products with different internal memory types and sizes and various package types.
