XY8106-RISC-51+DSP-Based Audio Platform
General Description
XY8106 is a highly integrated single-chip digital audio system. It is built in a variety of popular audio codec, which includes mp3 decoder, WMA decoder, IMA ADPCM encoder, IMA ADPCM decoder, JPEG decoder, and Motion JPEG. A high performance DSP is in charge of the decoding and encoding, and a USB2.0-device interface is responsible for transferring audio and/or voice data between XY8106 and any USB host. XY8106 also includes interfaces for NAND flash, SD/MMC, SPI, LED/LCD, push button, headphone, microphone, and FM radio.
Besides used in a portable audio player, XY8106 can also be used in the USB mass storage, which is capable of connecting with personal computers. XY8106’s high power DC-DC converter with excellent conversing efficiency can extensively prolong the long battery life. The built-in Sigma-Delta DAC includes a headphone driver to drive directly low impedance headphones. XY8106 is a true “all-in-one” solution which is suitable for highly optimized digital audio plays with a mass storage.
