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 microcom-
puters 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 pro-
gramming.
The M37221EF-XXXSP and M37221EFSP have a PWM output func-
tion and a OSD display function, so it is useful for a channel selection
system for TV.
