FIE7006 is a highly integrated single-chip digital audio system. It is built in a variety of popular audio codecs, including 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 USB 2.0 device interface is responsible for transferring audio and/or voice data between FIE7006 and the USB host. FIE7006G also includes interfaces for NAND flash, SPI, LED/LCD, push buttons, headphones, microphones, and FM radios.
