Description

The M16C/62A 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 100-pin plastic molded QFP.

These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruc-

tion efficiency. With 1M 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/62A group includes a wide range of products with different internal memory types and sizes and

various package types.
