M37225ECSP
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER
with ON-SCREEN DISPLAY CONTROLLER
1. DESCRIPTION
The M37225M6-XXXSP, M37225M8-XXXSP, and M37225ECSP are
single-chip microcomputers designed with CMOS silicon gate tech-
nology. They have a OSD, I
2
C-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 difference between M37225M6-XXXSP
and M37225M8-XXXSP are the ROM size. Accordingly, the follow-
ing descriptions will be for the M37225M6-XXXSP.
