M37630M4T Datasheet, PDF (1/48 Pages) Mitsubishi Electric Semiconductor – SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER

MITSUBISHI MICROCOMPUTERS
7630 Group
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 cir-
cuit, 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 microcom-
puters are available as well.
