1 / 171 page SNGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER and ON-SCREEN DISPLAY CONTROLLER REJ03B0130-0100Z Rev.1.00 Apr 01, 2002 Rev.1.00 Apr 01, 2002 page 1 of 169 REJ03B0130-0100Z 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. 2.
