GENERAL DESCRIPTION
The SAA55xx standard 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 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), Video Programming System (VPS) and
Wide Screen Signalling (WSS) information. The same
display hardware is used both for Teletext and OSD, which
means that the display features available give greater
flexibility to differentiate the TV set.
The SAA55xx standard family offers a range of
functionality from non-text, 16-kbyte program ROM and
256-byte Random Access Memory (RAM), to a 10-page
text version, 64-kbyte program ROM and 1.2-kbyte RAM.
