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 Introduction

VMusic3 is designed to support quick and easy

integration of a UART/SPI application with a

USB client device. VMusic3 also supports

playback of MP3 and WMA. The VMusic3 is

packaged in a neat enclosure displaying a bi-

colour LED, making it suitable for

incorporating into finished product designs.

The VMusic3 utilises FTDI’s Vinculum-II (VNC2-

48L1B) dual USB host controller IC. This IC is a

microcontroller and USB host controller; it can

be reprogrammed using the UART interface or

the Vinculum-II debugger module interface

connecter. The default firmware used is

V2MSC, this firmware supports the UART/SPI

to USB host interface and MP3 playback. This

firmware can be modified or replace with

another firmware.

The VMusic3 also utilises VLSI Solution’s

VS1053b compressed audio codec to provide

the audio play back feature. This chip operates

with the Vinculum-II and supporting firmware

when reading MP3 and WMA files from a USB

flash drive. The VS1053b processes this data

and outputs the stereo audio to the headphone

jack and line-out header. Connecting

headphones or speakers to either of these

ports transduces the audio data into sound.
