DESCRIPTION

The M37160M8/MA/MF-XXXSP/FP and M37160EFSP/FP are single chip microcomputers designed with CMOS silicon gate technology. They have an OSD and I2C-BUS interface, making them perfect for a channel selection system for TV. The M37160EFSP/FP has a built-in PROM that can be written electrically.
