GENERAL DESCRIPTION
The SAA7348 All Compact Disc Engine (ACE) combines
the functionality of a CD decoder (LO9585), a digital servo
(OQ8868) and a microcontroller core (80C51 based) on a
single chip. It was developed for high speed CD-ROM
applications but, due to the large scale integration, can
also be used in other CD applications. The internal
microcontroller makes it possible to develop other
applications quickly. The microcontroller can operate with
internal or external ROM.
Additional features include:
High level integration
Improved communication speed.
