SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER and ON-SCREEN DISPLAY CONTROLLER
1. DESCRIPTION
The M37281MAH–XXXSP, M37281MFH–XXXSP and M37281MKHXXXSP 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 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.
