GENERAL DESCRIPTION
The SAA55xx 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, On-Screen Display (OSD) and some
versions include an integrated data capture and display
function.
The data capture hardware has the capability of decoding
and displaying both 525 and 625-line World System
Teletext (WST), Closed Caption (CC) information, Video
Programming Information (VPS) and Wide Screen
Signalling (WSS) information. The same display hardware
is used both for Teletext, Closed Caption and On-Screen
Display, which means that the display features available
give greater flexibility to differentiate the TV set.
The SAA55xx family offers a range of functionality from
non-text, 16-kbyte program ROM and 256-byte RAM, to a
10 page text version, 128-kbyte program ROM and
2.25-kbyte RAM.
