M37420E6SS
PROM VERSION of M37420M6-XXXSP
DESCRIPTION
The M37420E6-XXXSP is a single-chip microcomputer de-
signed with CMOS silicon gate technology. It is housed in a
52-pin shrink plastic molded DIP. The features of this chip
are similar to those of the M37420M6-XXXSP except that
this chip has a 12288 bytes PROM builtin. This single-chip
microcomputer is useful for home electrical appliances and
consumer appliance controllers.
In addition to its simple instruction sets, the PROM, RAM,
and I/O addresses are placed on the same memory map to
enable easy programming. Since general purpose PROM
writers can be used for the built-in PROM, this chip is suit-
able for small quantity production runs.
The M37420E6SS is the window type.
