Description
S5L9276 (PRELIMINARY SPEC)
OPTICAL CD MP3 SYSTEM
INTRODUCTION
64-LQFP-1010 S5L9276 is a single chip ISO/IEC 11172-3 Layer III audio decoder, capable of decoding compressed elementary bit stream as specified in ISO/IEC standard.
As a decoder for the DISC-MAN, it can provide you more small and cheaper solution for MP3 player application.
S5L9276 is low voltage IC that can read MP3 and CD-ROM format discs and can be applied to various products.
