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 I²C-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.
