PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The M37221M6-XXXSP is a single-chip microcomputer designed with
CMOS silicon gate technology. It is housed in a 42-pin shrink plastic
molded DIP.
In addition to their simple instruction sets, the ROM, RAM and I/O
addresses are placed on the same memory map to enable easy pro-
gramming.
The M37221M6-XXXSP has a PWM output function and a OSD dis-
play function, so it is useful for a channel selection system for TV.
