VS1033 - MP3/AAC/WMA/MIDI

AUDIO CODEC

Features

Description

• Decodes MPEG 1 & 2 audio layer III (CBR

+VBR +ABR); layers I & II optional;

MPEG4 / 2 AAC-LC-2.0.0.0 (+PNS);

WMA 4.0/4.1/7/8/9 all proﬁles (5-384 kbps);

WAV (PCM + IMA ADPCM);

General MIDI / SP-MIDI format 0 ﬁles

• Encodes IMA ADPCM from microphone

or line input

VS1033 is a single-chip MP3/AAC/WMA/MIDI

audio decoder and ADPCM encoder. It contains

a high-performance, proprietary low-power DSP

processor core VS DSP⁴, working data memory,

5 KiB instruction RAM and 0.5 KiB data RAM

for user applications, serial control and input data

interfaces, upto 8 general purpose I/O pins, an

UART, as well as a high-quality variable-sample-

rate mono ADC and stereo DAC, followed by an

earphone ampliﬁer and a ground buffer.

• Streaming support for MP3 and WAV

• Bass and treble controls

• Operates with a single clock 12..13 MHz.

• Can also be used with 24..26 MHz clocks.

• Internal PLL clock multiplier

VS1033 receives its input bitstream through a se-

rial input bus, which it listens to as a system slave.

The input stream is decoded and passed through a

digital volume control to an 18-bit oversampling,

multi-bit, sigma-delta DAC. The decoding is con-

trolled via a serial control bus. In addition to the

basic decoding, it is possible to add application

speciﬁc features, like DSP effects, to the user RAM

memory.

• Low-power operation

• High-quality on-chip stereo DAC with no

phase error between channels

• Stereo earphone driver capable of driving a

30 load

• I2S interface for external DAC

• Separate operating voltages for analog, dig-

ital and I/O

• 5.5 KiB On-chip RAM for user code / data

• Serial control and data interfaces

• Can be used as a slave co-processor

• SPI ﬂash boot for special applications

• UART for debugging purposes

• New functions may be added with software

and 8 GPIO pins

• Lead-free RoHS-compliant package (Green)
