DESCRIPTION

The M37161M8/MA/MF-XXXSP/FP and M37161EFSP/FP are singlechip 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 M37161EFSP/FP has a built-in PROM that can be written electrically.
