GENERAL DESCRIPTION
The SAA55xx OSD only family of devices 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 function.
The main differences between the OSD only family and the
SAA55xx Text/CC family of baseline devices are:
•
Program ROM size: 16 to 64-kbyte
•
Display RAM size: 1.25-kbyte (1 page Text OSD or
CC/OSD)
•
Auxiliary RAM size: 0.75-kbyte
•
No teletext data capture (Closed Caption only)
•
Additional power saving mode (Standby).
