SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
M37273M8–XXXSP, M37273MF–XXXSP
M37273E8SP, M37273EFSP
MITSUBISHI MICROCOMPUTERS
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
2
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.
