MITSUBISHI MICROCOMPUTERS
7531 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 7531 Group is the 8-bit microcomputer based on the 740 family
core technology.
The 7531 Group has a serial I/O, 8-bit timers, and an A-D converter,
and is useful for control of home electric appliances and office auto-
mation equipment.
