MITSUBISHI MICROCOMPUTERS M37221EF-XXXSP,M37221EFSP SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER with ON-SCREEN DISPLAY CONTROLLER DESCRIPTION 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. www.DataSheet4U.
