M37421M6-XXXSP/FP
SINGLE-CHIP a-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37421 M6-XXXSP is a single-chip microcomputer de-
signed with CMOS silicon gate technology. It is housed in a
64-pin shrink plastic molded DIP (flat package type also
available) . This single-chip microcomputer is useful for
business equipment and other consumer applications.
In addition to their 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 M37421 M6-XXXSP and the
M37421 M6-XXXFP are the package outline and the power
dissipation ability (absolute maximum ratings).
