1. DESCRIPTION
The M37212M6-XXXSP/FP, M37212M4/M8-XXXSP are single-chip
microcomputers designed with CMOS silicon gate technology. They
have a OSD, I2C-BUS interface, and PWM, so it is useful for a chan-
nel selection system for TV.
The feature of the M37212EFSP/FP are similar to those of the
M37212M6-XXXSP/FP except that these chips have a built-in PROM
which can be written electrically. The differences between the
M37212M6-XXXSP/FP and M37212M4/M8-XXXSP are the ROM size
and the RAM size as shown below. Accordingly, the following de-
scriptions will be for M37212M6-XXXSP/FP unless otherwise noted.
