VMUSIC3

VMusic3 Version 1.0 Document Reference No.: FT 000738 Clearance No.: FTDI 336 Future Technology Devices International Ltd Datasheet VMusic3 Vinculum-II Application Module VMusic3 is a USB host and MP3/WMA Player application module with an enclosure. The default firmware of the VMusic3 supports audio playback and UART/SPI communications with the embedded USB host controller and USB host port. VMusic3 can be used to read MP3 and other audio format files from a USB flash disk process the data and output the stereo audio through the line-out header and headphone jack. 1.1 Features 1 Introduction VMusic3 has the following features: VMusic3 is designed to support quick and easy integration of a UART/SPI application with a MP3 and WMA playback USB client device. VMusic3 also supports playback of MP3 and WMA. The VMusic3 is Vinculum-II microcontroller/USB host packaged in a neat enclosure displaying a bi- controller IC. colour LED, making it suitable for incorporating into finished product designs. USB A type socket to connect to USB client devices. The VMusic3 utilises FTDIs Vinculum-II (VNC2- 48L1B) dual USB host controller IC. This IC is a 2mm (0.08) pitch 8 pin header used for microcontroller and USB host controller it can the UART/SPI interface. be reprogrammed using the UART interface or the Vinculum-II debugger module interface Connects directly and communicates with connecter. The default firmware used is a FTDI TTL-232R-3V3-2mm USB-UART V2MSC, this firmware supports the UART/SPI cable. to USB host interface and MP3 playback. This firmware can be modified or replace with Jumper selectable UART and SPI another firmware. interfaces, both operating 3.3V TTL/CMOS. The VMusic3 also utilises VLSI Solutions VS1053b compressed audio codec to provide Pre-programmed with V2MSC firmware. the audio play back feature. This chip operates with the Vinculum-II and supporting firmware Vinculum-II debugger module port under when reading MP3 and WMA files from a USB the enclosure, for changing the firmware flash drive. The VS1053b processes this data and debugging. and outputs the stereo audio to the headphone jack and line-out header. Connecting UART programming mode control pins headphones or speakers to either of these PROG and RESET are connected to an ports transduces the audio data into sound. internal header.
