Description
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
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.
