1. DESCRIPTION
The M37225M6/M8/MA/MC–XXXSP are single-chip microcomput-
ers 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.
