One page Economy Teletext/TV microcontroller
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. ORDERING INFORMATION PACKAGE TYPE NUMBER SAA5290ZP/nnn(1) SAA5290ZP/NVI(2) Notes 1. nnn is a three-digit number referencing the microcontroller program ROM mask. 2. I is a digit number referring to the language variant of the SAA5290ZP/NV. MEMORY NAME ROM EEPROM SDIP52 SDIP52 DESCRIPTION DESCRIPTION
SAA5290
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.
