DESCRIPTION

The M37210M3-XXXSP/FP is a single-chip microcomputer designed with CMOS silicon gate technology. It is housed in a 52-pin shrink plastic molded DIP or a 64-pin plastic molded QFP. This single-chip microcomputer is useful for the channel selection system for TVs because it provides PWM function, OSD display function and so on. 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.
