M37273E8SP, M37273EFSP

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

and ON-SCREEN DISPLAY CONTROLLER

1. DESCRIPTION

The M37273M8-XXXSP and M37273MF-XXXSP are single-chip mi-

crocomputers designed with CMOS silicon gate technology. They

have a OSD, data slicer, and I

C-BUS interface, so it is useful for a

channel selection system for TV with a closed caption decoder.

The features of the M37273E8SP and M37273EFSP are similar to

those of the M37273M8-XXXSP and M37273MF-XXXSP except that

the chip has a built-in PROM which can be written electrically. The

difference between M37273M8-XXXSP and M37273MF-XXXSP are

the ROM size and RAM size. Accordingly, the following descriptions

will be for the M37273M8-XXXSP.
