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.
