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.
