M37280MF鈥揦XXSP, M37280MK鈥揦XXSP

M37280EKSP

SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER

and ON-SCREEN DISPLAY CONTROLLER

1. DESCRIPTION

The M37280MF鈥揦XXSP 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.
