VS1053B-L Description

Short technical summary and product information.

The VS1053B-L from VLSI Solution is a versatile slave audio processor chip designed for decoding and encoding various audio formats. It supports popular formats such as Ogg Vorbis, MP3, AAC, WMA, FLAC, and MIDI. The functionality of this IC can be expanded by loading extra software into its 16.5 KiB on-chip RAM.

In addition to decoding, the VS1053B-L is capable of recording in three different formats, including lossless 16-bit PCM and compressed Ogg Vorbis. It includes features like EarSpeaker spatial processing for enhanced headphone listening, bass and treble controls, and a high-quality on-chip stereo DAC with no phase error. The chip operates with a single 12-13 MHz clock and features an I2S interface for external DACs, along with serial control and data interfaces.

Packaged in an LQFP48 (7x7x1.4mm), the VS1053B-L is suitable for audio playback and recording applications. It offers separate voltage supplies for analog, digital, and I/O, and includes a stereo earphone driver capable of driving a 30-ohm load. The chip also supports SPI flash boot for special applications and has UART for debugging purposes, with up to 8 GPIO pins available for new functions.
