VS1053 - Ogg Vorbis / MP3 / AAC / WMA / FLAC / MIDI Audio Codec Chip

Block diagram

Introduction

VS1053 is a versatile "MP3 decoder chip" belonging to VLSI Solution's extensive slave audio processor family. In addition to being able to decode all the most common audio formats - including the advanced features of newer AAC files - functionality of this IC can be greatly expanded just by loading a bit of extra software to its RAM memory. In addition to being able to decode all major audio formats, VS1053 is capable of recording in three different audio formats, from lossless 16-bit PCM to highly compressed, yet high-quality Ogg Vorbis files. For the best headphone listening experience the VS1053 includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. This option can naturally be turned off when required. All in all, VS1053 is an easy-to-use, powerful workhorse for audio playback and recording applications.
