VS1003 概述

VS1003 is a versatile slave MP3 and WMA decoder chip, replacing the discontinued VS1002. It can record wideband speech quality audio and play MIDI either from files or using a standard serial MIDI keyboard with the Real-Time MIDI Input Application. Many wide-ranging applications have been developed for this IC that has sold more than 5 million units.
