SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

Description

The M30218 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 instruction

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 musical instruments, house-

hold appliances and other high-speed processing applications.

The M30218 group includes a wide range of products with different internal memory types and sizes and

various package types.
