Philips Semiconductors
Preliminary specification
Economy teletext and TV microcontrollers
SAA5x9x family
2
GENERAL DESCRIPTION
The SAA529x, SAA529xA and SAA549x 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 and include an integrated teletext function.
The teletext hardware has the capability of decoding and
displaying both 525-line and 625-line World System
Teletext. The same display hardware is used both for
Teletext and On-Screen Display, which means that the
display features give greater flexibility to differentiate the
TV set.
The family offers both 1 page and 10 page Teletext
capability, in a range of ROM sizes. Increasing display
capability is offered from the SAA5290 to the SAA5497.
2.1
Device masking history
A number of mask variants have been produced for the
ETT family of devices. The current mask variants available
are:
SAA5x90 M5A
SAA5x91 M1A
SAA5x96 M5A
SAA5x97 M1A.
There have been two design issues with the M1 mask,
which required resolving, these brought about the
introduction of the M1A mask:
Spanish G3 arrows
OSD twist effect.
The Spanish G3 arrows issue was only encountered on
the Pan-European device, it became apparent that an
up arrow and a right arrow were missing from the Spanish
character map.
The OSD twist effect was inherent on all devices, although
not visible on the Pan-European version. Essentially, OSD
characters had the ability to set and reset the serial
attribute “twist”. This effect is described in detail in
Application note “SPG/AN97004 Version 1.0”
