1 1.1 FEATURES General
SAA5288
· 260 characters in mask programmed ROM · Display clock derived internally to reduce peripheral components to a minimum · Automatic FRAME output control with manual override · Standby mode for display hardware · 525-line and 625-line display · 12 × 10 character matrix · Stable Display via slave synchronization to Horizontal Sync and Vertical Sync. 2 GENERAL DESCRIPTION
· On-chip TV control tuning · Hardware and software compatible with SAA5290, SAA5291 and SAA5296 · Single +5 V power supply · RGB interface to standard decoder ICs, push-pull output drive · SDIP52 package · Single crystal oscillator for display and microcontroller. 1.2 Microcontroller
· 80C51 microcontroller core · 16 kbyte mask programmed ROM · 256 bytes of microcontroller RAM · Eight 6-bit Pulse Width Modulator (PWM) outputs for control of TV analog signals · One 14-bit PWM for Voltage Synthesis tuner control · Four 8-bit Analog-to-Digital Converters (ADCs) · 2 high current open-drain outputs for directly driving LED's etc. · Switchable bit or byte-oriented 1.3 Display I2C-bus interface.
The SAA5288 is a microcontroller for use in televisions with an OSD generator compatible with the Economy Teletext/TV microcontroller family (SAA5290, SAA5291, SAA5296 etc.). TV control facilities are provided by an on-chip industry standard 80C51 microcontroller and a 1 kbyte DRAM is included for OSD memory. Hardware and software compatibility with the Economy Teletext/TV microcontroller family minimizes the changes required to develop a TV control function for areas where teletext is not broadcast. The device cannot acquire Teletext but is based on a Teletext device. Therefore, throughout this document references are made to Teletext especially when describing the Display/OSD section. The Display/OSD section is fully compatible with a Teletext display and has all the features associated with Teletext (i.e. double height/width, flash, teletext boxes, graphics, etc.). The Display section is described with reference to Teletext to allow software compatibility with the Economy Teletext/TV microcontroller family.
