1. DESCRIPTION
The M37280MF–XXXSP and M37280MK-XXXSP are single-chip
microcomputers designed with CMOS silicon gate technology. They
have a OSD function and a data slicer function, so it is useful for a
channel selection system for TV with a closed caption decoder.
The feautures of the M37280EKSP is similar to those of the
M37280MK-XXXSP except that the chip has a built-in PROM which
can be written electrically. The difference between M37280MK-XXXSP
and M37280MF-XXXSP are the ROM size and RAM size. Accord-
ingly, the following descriptions will be for the M37280MK-XXXSP.
