VLSI: VS1005G-Q

All-in-one audio processor chip, supports MP3 decoding

VS1005 is a flexible audio platform device. It is built around the powerful DSP (Digital Sound Processor) core VS_DSP4 and runs VLSI Solution’s proprietary DSP-oriented, multitasking VSOS operating system.
VS1005’s 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 complex systems. The analog interfaces provide high-quality audio inputs and outputs, and the control ADC can, for example, be used for interfacing a resistive touch panel.
VS1005 is offered in different variants.
