1. DESCRIPTION
The M37150M6/M8/MA/MC/MF-XXXFP and M37150EFFP are
single-chip microcomputers designed with CMOS silicon gate tech-
nology. They have an OSD, data slicer, and I
2
C-BUS interface, mak-
ing them perfect for TV channel selection systems with a closed cap-
tion decoder. The M37150EFFP has a built-in PROM that can be
written electrically.
