General Description
M37273MF-XXXSP General Description
The M37273MF-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 programming. The M37273MF-XXXSP has a OSD function and a data slicer function, so it is useful for a channel selection system for TV with a closed caption decoder. The features of the M37273EFSP are similar to those of the M37273MF-XXXSP except that these chips have a builtin PROM which can be written electrically.
