SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
M37272M6/M8–XXXSP/FP, M37272MA–XXXSP
M37272E8SP/FP, M37272EFSP
MITSUBISHI MICROCOMPUTERS
Rev. 1.4
1. DESCRIPTION
The M37272M6/M8-XXXSP/FP and M37272MA-XXXSP are single-
chip microcomputers designed with CMOS silicon gate technology.
They have a OSD, data slicer, and I
2
C-BUS interface, so it is useful
for a channel selection system for TV with a closed caption decoder.
The features of the M37272E8SP/FP and M37272EFSP are similar
to those of the M37272M6-XXXSP except that the chip has a built-in
PROM which can be written electrically. The difference between
M37272M6-XXXSP/FP, M37272M8-XXXSP/FP and M37272MA-
XXXSP are the ROM size and RAM size. Accordingly, the following
descriptions will be for the M37272M6-XXXSP/FP.
