SmartMP3 Board  (MIKROE-200)

SmartMP3 Board is provided with a VS1011e MPEG audio decoder with MMC/SD card support.

Description

The SmartMP3 Board features a single-chip MPEG audio decoder VS1011e. The chip includes a high-performance, low-power DSP processor core VS DSP4, working memory, 5 KiB instruction RAM and 0.5 KiB data RAM for user applications, serial control and input data interfaces, 4 general purpose I/O pins, as well as a high-quality variable-sample-rate stereo DAC, followed by an earphone amplifier and a common buffer.

VS1011e receives its input bitstream through a serial input bus 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 process 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.
