OTi Ours Technology Inc. OTi-6888 USB 1.1 USB Host with MP3 Interface Controller DESCRIPTION The OTi-6888 is a USB host with MP3 interface controller. User can stores the mp3 file in the USB device (USB flash disk , USB card reader and USB portable hard Disk). When the USB device plug in USB port and push the play key. The OTi6888 will read the mp3 file from USB device, and send the data to MP3 decoder and DAC. The user can hear MP3 song where stores in USB device. The USB interfaces are for full speed operation (12Mb/s). It conforms to USB Specification, Version 1.1. The USB transceiver is embedded in this controller. With stable slew-rate control, the controller reduces EMI. The OTi-6888 has a Phase Lock Loop (PLL) embedded. The PLL provides all clocks needed in this controller. It needs an externally provided clock operating in 14.318MHz. The controller has two LED control pin. FEATURES ♦ The host controller conforms to Full-speed (12Mb/s) USB Specification, Version 1.1 ♦ Supports the USB flash disk device(Version 1.1 or 2.0) with Mass storage class ♦ Supports the USB card reader device(Version 1.1 or 2.0) with Mass storage class ♦ Supports the USB portable hard disk(Version 1.1 or 2.0) with Mass storage class ♦ Integrated USB transceiver ♦ Integrated RISC micro-controller — High-performance RISC architecture — Single cycle instruction execution ♦ 14.318 MHz external clock ♦ 3.3 V power operation ♦ Integrated PLL ♦ Small form factor - standard 48-pin LQFP (7mmX7mm) package ♦ Supports File System including FAT12、FAT16、FAT32 ♦ Search for whole disk (MP3 File) ♦ Input button for Play (Pause), Previous, Next , Volume + and Volume – - 1 - Our Technologies are Yours!
