VLSI VS1010D-Q

VS1010d is a flexible audio platform device. It is built around VS_DSP4, which is a powerful DSP (Digital Signal Processor) core. The digital interfaces provide flexible access to external devices in standalone applications and flexible digital audio data inputs and outputs when the device is used as an audio signal processor in more complex systems. The analog interfaces provide high-quality audio outputs, and the control ADC can be used for example for interfacing a resistive touch panel.
