DESCRIPTION The M37151M6/M8/MA/MC/MF-XXXFP and M37151EFFP are single-chip microcomputers designed with CMOS silicon gate tech- nology. They have an OSD, data slicer, and I2C-BUS interface, mak- ing them perfect for TV channel selection systems with a closed cap- tion decoder. The M37151EFFP has a built-in PROM that can be written electrically. 2.
