Preliminary speciﬁcation

Economy teletext and TV microcontrollers

SAA5x9x family

FEATURES

General

1.4

Teletext Display

• 525-line and 625-line display

• 12 × 10 character matrix

1.1

• Single chip microcontroller with integrated teletext

decoder

• Double height, width and size On-Screen Display (OSD)

• Definable border colour

• Single +5 V power supply

• Single crystal oscillator for teletext decoder, display and

• Enhanced display features including meshing and

microcontroller

shadowing

• Teletext function can be powered-down independently

of microcontroller function for reduced power

consumption in stand-by

• 260 characters in mask programmed ROM

• Automatic FRAME output control with manual override

• RGB push pull output to standard decoder ICs

• Pin compatibility throughout family.

• Stable display via slave synchronisation to Horizontal

Sync and Vertical Sync.

1.2

Microcontroller

• 80C51 microcontroller core

1.5

Additional features of SAA529xA devices

• 16/32/64 kbyte mask programmed ROM

• 256/768/1280 bytes of microcontroller RAM

• Wide Screen Signalling (WSS) bit decoding (line 23).

1.6

Additional features of SAA549x devices

• Eight 6-bit Pulse Width Modulator (PWM) outputs for

control of TV analog signals

• Wide Screen Signalling bit decoding (line 23)

• Quad width OSD capability

• One 14-bit PWM for Voltage Synthesis Tuner control

• Four 8-bit Analog-to-Digital converters

• 32 additional OSD characters in mask programmed

• 2 high current open-drain outputs for directly driving

ROM

LED’s etc.

• I²C-bus interface

• 8 foreground and 8 background colours definable from a

palette of 64.

• External ROM and RAM capability on QFP80 package

version.

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.

1.3

Teletext acquisition

• 1 page and 10 page Teletext version

• Acquisition of 525-line and 625-line World System

Teletext, with automatic selection

• Acquisition and decoding of VPS data (PDC system A)

• Page clearing in under 64 µs (1 TV line)

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.

• Separate storage of extension packets

(SAA5296/7, SAA5296/7A and SAA5496/7)

• Inventory of transmitted Teletext pages stored in the

Transmitted Page Table (TPT) and Subtitle Page Table

(SPT) (SAA5296/7, SAA5296/7A and SAA5496/7)

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.

• Automatic detection of FASTEXT transmission

• Real-time packet 26 engine for processing accented

(and other) characters

• Comprehensive Teletext language coverage

• Video signal quality detector.
