M37274EFSP General Description


The M3727EFSP 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 M3727EFSP 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.
