M37420M6-XXXSP
SINGLE·CHIP a·BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37420M4-XXXSP and the M37420M6-XXXSP are
single-chip microcomputers designed with CMOS silicon
gate technology. All are housed in a 52-pin shrink plastic
molded DIP.
These single-chip microcomputers are useful for household
appliance and other consumer applications.
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,
The differences between the M37420M4-XXXSP and the
M37420M6-XXXSP are noted below. The following explana-
tions apply to the M37420M6-XXXSP.
Specification variations for other chips are noted accor-
dingly.
