DESCRIPTION

The M37150M6/M8/MA/MC/MF-XXXFP and M37150EFFP are single-chip microcomputers designed with CMOS silicon gate technology. They have an OSD, data slicer, and I2C-BUS interface, making them perfect for TV channel selection systems with a closed caption decoder. The M37150EFFP has a built-in PROM that can be written electrically.
