DESCRIPTION The M37225M6/M8/MA/MC–XXXSP are single-chip microcomputers designed with CMOS silicon gate technology.
They have a OSD, I2C-BUS interface, PWM output, and 12 V withstand, so it is useful for a channel selection system for TV.
The features of the M37225ECSP are similar to those of the M37225M6-XXXSP except that the chip has a built-in PROM which can be written electrically.
The differences amang M37225M6/M8/ MA/MC–XXXSP are the ROM, RAM size.
Accordingly, the following descriptions will be for the M37225M6-XXXSP.
