SAA567x Datasheet

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. They provide
control functions for the television system, OSD and incorporate an integrated Data Capture and display function for either Teletext or Closed Caption.

The devices 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 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 is specified in Chapter 4

The family of devices offers 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.
