Preliminary specification
SAA5290
FEATURES
General
• Complete one page teletext decoder and TV
microcontroller in a single 52-pin package
• Eastern European, Western European and Turkish
language variants covered in one device
• Double size, double width and double height character
capability for On-Screen Display (OSD)
• Enhanced display features including meshing and
shadowing
• Separate display and acquisition timing for increased
flexibility
• Minimum peripheral component count
• 525 line and 625 line display synchronization
• Standby mode through power-down of teletext and
analog hardware.
Microcontroller
• 16 kbytes masked ROM (16 kbytes EEPROM variant for
product development)
• 256 bytes of on-chip RAM
• Six 6-bit Pulse Width Modulators (PWM) and one 14-bit
precision PWM
• 4-bit Digital-to-Analog Converter (DAC) and comparator
with a 3-input multiplexer allowing implementation of 3
Analog-to-Digital Converters (ADC) in software
• 2 high current (10 mA) open-drain outputs
• Interrupt logic 0 triggered on rising and falling edges,
providing pulse-width measurement for remote control
decoding
• Master and slave bit-level I2C-bus hardware.
DESCRIPTION
The SAA5290 is a single-chip one page teletext decoder
and television control microcontroller. The device will
decode 625-line based World System Teletext
transmissions and provides television control functions
and On-Screen Display (OSD) functions.
The teletext decoder hardware is a derivative of the
SAA5254 (IVT1.1X), and the TV control functionality
provided by an on-chip industrial standard 80C51
microcontroller. A single-page static RAM is included
on-board providing a complete one page teletext decoder
and OSD memory.
The SAA5290 is available as a mask-programmed ROM
version. An EEPROM version is also available for product
development. Both versions are available in an SDIP52
package.
