1. DESCRIPTION
The M37281MAH–XXXSP, M37281MFH–XXXSP and M37281MKH-
XXXSP are single-chip microcomputers designed with CMOS silicon
gate technology. They have a OSD function and a data slicer func-
tion, so it is useful for a channel selection system for TV with a closed
caption decoder.
The feautures of the M37281EKSP is similar to those of the
M37281MKH-XXXSP except that the chip has a built-in PROM which
can be written electrically. The difference between M37281MAH–
XXXSP, M37281MKH-XXXSP and M37281MFH-XXXSP are the ROM
size and RAM size. Accordingly, the following descriptions will be for
the M37281MKH-XXXSP.
