SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37451 M4-XXXSP/FP/GP is a single-chip micro-
computer designed with CMOS silicon gate technology. It
is housed in a 64-pin shrink plastic molded DIP or a
0.8mm-pitch or 0.65mm-pitch 80-pin plastic molded QFP.
In addition to its simple instruction sets, the ROM, RAM,
and I/O addresses are placed on the same memory map to
enable easy programming.
It is suited for office automation equipment and control de-
vices The low power consumption made by the use of a
CMOS process makes it especially suitable for battery po-
wered devices requiring low power consumption. It also
has a unique feature that enables it to be used as a slave
microcomputer.
The differences among M37451 M4-XXXSP/FP/GP, M37451
M8-XXXSP/FP/GP and M37451 MC-XXXSP/FP/GP are as
shown below. The descriptions that follow describe the
M37451M4-XXXSP/FP/GP (abbreviated as M37451) un-
less otherwise noted.

The number of analog input pins for the 80-pin model (FP,
GP version) is different from the 64-pin model (SP version).
In addition, the 80-pin model has special pins for RD, WR,
RESETOUT, DAVREF, ADVREF, AVec and the 64-pin model
has a special VREF pin.
