DESCRIPTION
The M37271MF-XXXSP is a single-chip microcomputer designed with
CMOS silicon gate technology. It is housed in a 52-pin shrink plastic
molded DIP.
In addition to their simple instruction sets, the ROM, RAM and I/O
addresses are placed on the same memory map to enable easy pro-
gramming.
The M37271MF-XXXSP has a OSD function and a data slicer func-
tion, so it is useful for a channel selection system for TV with a closed
caption decoder. The features of the M37271EF-XXXSP and the
M37271EFSP are similar to those of the M37271MF-XXXSP except
that these chips have a built-in PROM which can be written electri-
cally.
