1. DESCRIPTION
The M37221M4/M8/MA-XXXSP, M37221M6-XXXSP/FP 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
channel selection system for TV.
The features of the M37221EASP/FP are similar to those of the
M37221MA-XXXSP except that these chips have a built-in PROM
which can be written electrically. The differences among the
M37221M4/M8/MA-XXXSP, M37221M6-XXXSP/FP are the ROM size
and the RAM size as shown below. Accordingly, the following de-
scriptions will be for M37221MA-XXXSP unless otherwise noted.
