描述 Description

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 programming. The M37221M6-XXXSP has a PWM output function and a OSD display function, so it is useful for a channel selection system for TV.FEATURES
