... One chip CD audio device Rev. 01 — 19 April 2005 1. General description The SAA7803 has the same features and pinning as the SAA7804 and SAA7806 devices. The SAA7803 is a multi chip module containing two additional memories, flash and SRAM, to support code development. This IC is intended for development use only and may therefore not comply with all aspects of the Philips Semiconductors general quality specifi ...
