The circuit contains 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 variablesample-rate stereo DAC, followed by an earphone amplifier and a common buffer.
VS1011e 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 digital volume control to an 18-bit oversampling, multi-bit, sigmadelta DAC.
The decoding is controlled via a serial control bus.
In addition to basic decoding, it is possible to add application specific features, like DSP effects, to the user RAM memory.
VS1011e can boot directly from SPI EEPROM to run standalone applications without a separate microcontroller.
