Description

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 0.5 KiB data RAM for user applications, serial control and input data interfaces, and a high-quality oversampling variable-sample-rate stereo DAC, followed by an earphone amplifier and a ground buffer.

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 an 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 to add application specific features, like DSP effects, to the user RAM memory.
