VS1001k is a single-chip soluTIon for an MPEG layer 3 audio decoder. The chip contains a highperformance low-power DSP processor (VS DSP),working memory, 4 KiB program RAM and 0.5KiB data RAM for user applicaTIons, serial controland input data interfaces, and a high-qualityoversampling variable-sample-rate stereo DAC, followedby an earphone amplifier and a ground buffer.VS1001k receives its input bitstream through aserial input bus, which it listens to as a systemslave. The input stream is decoded and passedthrough a analog/digital hybrid volume control toan 18-bit oversampling mulTI-bit sigma-delta DAC.The decoding is controlled via a serial control bus.In addiTIon to the basic decoding, it is possible toadd application specific features, like DSP effects, to the user RAM memory.
