Description
The M16C/62N 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, 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 pro-
cessing applications.
The M16C/62N group includes a wide range of products with different internal memory types and sizes and
various package types.
