The M37221EF-XXXSP and M37221EFSP are single-chip microcomputers designed with CMOS silicon gate technology. They are 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 programming.
The M37221EF-XXXSP and M37221EFSP have a PWM output function and a OSD display function, so it is useful for a channel selection system for TV.
