The SAA567x; SAA569x family of microcontrollers are a derivative of the Philips industry-standard 80C51 microcontroller and are intended for use as the central control mechanism in a television receiver. SAA567x; SAA569x provide control functions for the television system, OSD and incorporate an integrated Data Capture and display function for either Teletext or Closed Caption.

The SAA567x; SAA569x offer all the features from the SAA56xx family with the addition of support for a range of Progressive Scan display modes.

The Data Capture hardware can decode and display both 525-line and 625-line World System Teletext (WST), Closed Caption information, Video Programming System (VPS) information and Wide Screen Signalling (WSS) information. The same display hardware SAA567x; SAA569x is used for Teletext, Closed Caption and On-Screen Display, which means that the display features available give greater flexibility to differentiate the TV set. The VBI data services supported by each device of SAA567x; SAA569x is specified in Chapter 4

The SAA567x; SAA569x family offer a range of memory variants with Program ROM sizes of 128 and 192 kbytes, also up to 14 kbytes of RAM.

Another new feature in the SAA567x; SAA569x family of products supports the addition of external ROM to provide up to a total of 256 kbytes of program ROM (e.g. 192 kbytes internal + 64 kbytes external to the SAA567x; SAA569x) with no external logic.
