Description

The M37224M3-XXXSP is a single-chip microcomputer 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 M37224M3-XXXSP addresses are placed on the same memory map to enable easy programming.

The M37224M3-XXXSP has a PWM output function and a OSD display function, so it is useful for a channel selection system for TV.
