Introduction

The VS1011 is VLSI Solution's basic MP3 decoder chip. It has a reliable and high-quality MP3 and WAV decoding engine combined with a stereo D/A converter and earphone amplifier. Although intended as slave processor, the VS1011 also has a standalone mode that can be used to create a simple standalone MP3 player. Available in two difference packages, this IC is truly customer-proven: over ten million units have been delivered!
