1. DESCRIPTION
The M3727GM6/M8-XXXSP/FP are single-chip microcomputers de-
signed with CMOS silicon gate technology. They have a OSD, data
slicer, and I
2
C-BUS interface, so it is useful for a channel selection
system for TV with a closed caption decoder.
The features of the M37272E8SP/FP are similar to those of the
M3727GM6/M8-XXXSP/FP except that these chips have a built-in
PROM which can be written electrically. The difference between
M3727GM6-XXXSP/FP and M3727GM8-XXXSP/FP are the ROM
size and RAM size. Accordingly, the following descriptions will be for
the M3727GM6-XXXSP/FP.
