DESCRIPTION

The 7630 group is a single chip 8-bit microcomputer designed with

CMOS silicon gate technology.

Being equipped with a CAN (Controller Area Network) module circuit,

the microcomputer is suited to drive automotive equipments. The

CAN module complies with CAN specification version 2.0, part B and

allows priority-based message management.

In addition to the microcomputers simple instruction set, the ROM,

RAM and I/O addresses are placed in the same memory map to

enable easy programming.

The built-in ROM is available as mask ROM or One Time PROM. For

development purposes, emulator- and EPROM-type microcomputers

are available as well.
