Description
VS1001k is a single-chip solution for an MPEG
layer 3 audio decoder. The chip contains a high-
performancelow-powerDSPprocessor(VS DSP),
working memory, 4 KiB program RAM and 0.5
KiB data RAM for user applications, serial con-
trol and input data interfaces, and a high-quality
oversamplingvariable-sample-ratestereoDAC,fol-
lowedbyanearphoneamplifierandagroundbuffer.
VS1001k receives its input bitstream through a
serial input bus, which it listens to as a system
slave. The input stream is decoded and passed
through a analog/digital hybrid volume control to
an18-bitoversamplingmulti-bitsigma-deltaDAC.

In addition to the basic decoding, it is possible to
addapplicationspecificfeatures, likeDSPeffects,
to the user RAM memory.
