GENERAL DESCRIPTION
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 eletext is not broadcast.
