Preliminary PT8921 Smart Audio Combo-Station with USB www.DataSheet4U.com Mini-Host & SD/MMC Host Interface Controller DESCRIPTION The PT8921 is a cost-efficient single chip for audio mini-combo play-station application. The chip integrated the USB2.0 FS host controller, SD/MMC host controller, Sigma-Delta Audio-DAC and WAV/MP3/WMA/AAC Audio-Decoder in one chip. Only few external components needed in application circuits makes it suite for the audio play-station system with USB2.0 FS host, SD/MMC host and i-Pod audio control interfaces. The I/O interfaces are totally following the USB2.0 FS host class interface specification and SD/MMC card specification. The stand alone audio play-station and no special driver software need to install on this system by user in the recent market.
