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.
