M37280MFH–XXXSP, M37280MKH–XXXSP, M37280EKSP

1. DESCRIPTION

The M37280MFH–XXXSP and M37280MKH-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

M37280MKH-XXXSP except that the chip has a built-in PROM which

can be written electrically. The difference between M37280MKH-

XXXSP and M37280MFH-XXXSP are the ROM size and RAM size.

Accordingly, the following descriptions will be for the M37280MKH-

XXXSP.
