SAA5264 Overview
The SAA5264 is a single-chip ten page 625-line World System Teletext decoder with a high-level mand interface, and is SAFARI patible. The SAA5265 is a single-chip one page version of the SAA5264. Both devices are designed to minimize the overall system cost, due to the high-level mand interface offering the benefit of a low software overhead in the TV microcontroller.
