1. DESCRIPTION
The M37221M4H/M6H/M8H/MAH-XXXSP/FP are single-chip micro-
computers designed with CMOS silicon gate technology. They have
a OSD, I2C-BUS interface, and PWM, making them perfect for TV
channel selection system.
The M37221EASP/FP have a built-in PROM that can be written elec-
trically.
