MITSUBISHI MICROCOMPUTERS

M37272M6H/M8H/MAH/MFH鈥揦XXSP/FP

M37272E8SP/FP, M37272EFSP/FP

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

and ON-SCREEN DISPLAY CONTROLLER

1. DESCRIPTION

The M37272M6H/M8H/MAH/MFH-XXXSP/FP are single-chip micro-

computers designed with CMOS silicon gate technology. They have

a OSD, data slicer, and I

C-BUS interface, so it is useful for a chan-

nel selection system for TV with a closed caption decoder.

The features of the M37272E8SP/FP and M37272EFSP/FP are simi-

lar to those of the M37272M6H-XXXSP/FP except that the chip has

a built-in PROM which can be written electrically. The difference be-

tween M37272M6H/M8H/MAH/MFH-XXXSP/FP are the ROM size

and RAM size. Accordingly, the following descriptions will be for the

M37272M6H-XXXSP/FP.
