MITSUBISHI MICROCOMPUTERS
7480/7481 GROUP
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 7480/7481 group is the single-chip microcomputer adopting
the silicon gate CMOS process. In addition to its simple instruction
set, the ROM, RAM, and I/O addresses are placed in the same
memory space.
Having built-in serial I/O, A-D converter, and watchdog timer, this
single-chip microcomputer is useful for control of automobiles, of-
fice automation equipment and home electric appliances.
The 7480/7481 group includes multiple types which differ in the
memory type, size, and package.

qA-D converter ............................ 8-bit x 4 channels (7480 group)
8-bit x 8 channels (7481 group)
qBuilt-in watchdog timer
qPower source voltage ................................................ 2.7 to 4.5 V
(at [2.2 VCC-2] MHz clock input oscillation frequency)
4.5 to 5.5 V
(at 8 MHz clock input oscillation frequency)
qPower dissipation .............................................................. 35 mW
(at 8 MHz clock input oscillation frequency and 5 V power
source voltage)
APPLICATIONS
Automobiles, office automation equipment, home electric appli-
ances, etc.
