The M35052-XXXSP/FP is TV screen display control IC which can be used to display information such as number of channels, the date and messages and program schedules on the TV screen. In particular, owing to the built-in SYNC-SEP (synchronous separation) circuit, the synchronous correction circuit, the Decoder circuit, and to the Encoder circuit, external circuits can be decrease and character turbulence that occurs when superimposing can be reduced. The processor can conform to the EDS broadcast service and is suitable for AV systems such as VTRs, LDs, and so on. It is a silicon gate CMOS process and M35052-XXXSP is housed in a 20-pin shrink DIP package, M35052-XXXFP is housed in a 20-pin shrink SOP package.
