Philips Semiconductors

Preliminary speciﬁcation

Economy teletext and TV microcontrollers

SAA5x9x family

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”.
