M37272E8FP General 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 I2C-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.
