2 GENERAL DESCRIPTION
The SAA56xx 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.
Additional features over the SAA55xx family have been
included, e.g. 100/120 Hz (2H/2V only) display timing
modes, two page operation (50/60 Hz mode for 16:9, 4:3),
higher frequency microcontroller, increased character
storage, more 80C51 peripherals and a larger Display
memory. For CC operation, only a 50/60 Hz display option
is available.
As with the rest of the SAA55xx family, 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 family of devices offers a range of memory variants
with Program ROM sizes of 128-kbyte and 192-kbyte, also
up to 14 kbytes of RAM.
