1. Introduction and Features
1.1 Introduction
The VMusic2 module is a product which not only lets you add USB Flash disk interfacing to your product, but also
allows you to play back MP3 and other popular digital music formats directly from a USB ash disk. Only four signal
lines plus 5V supply and ground are required to be connected. Extensions to the Vinculum VDAP command set allow
you to play a selected le, as well as control the volume, balance, etc. of the sound channel, and monitor the status
of the le being played. The Vinculum VDAP rmware also allows the VNC1L’s I/O interface to be selected between
the serial UART or SPI using on-board jumper pins. The VMusic2 is ideal for adding MP3 playbackfrom USB drive
capabillity to home entertainment and in-car audio systems, as well as other appliances requiring audio playback
capabillity from USB Flash disks. Not only is the VDrive2 ideal for evaluation and development of VNC1L designs,
but also its neat enclosure and attractive quantity discount structure makes this module suitable for incorporation into
nished product designs.
The Vinculum VNC1L is the rst of F.T.D.I.’s Vinculum family of Embedded SoC USB host controller integrated circuit
devices. Not only is it able to handle the USB Host Interface, and data transfer functions but owing to the inbuilt MCU
and embedded Flash memory, Vinculum can encapsulate the USB device classes as well. When interfacing to mass
storage devices such as USB Flash drives, Vinculum also transparently handles the FAT le structure communicating
via UART, SPI or parallel FIFO interfaces via a simple to implement command set. Vinculum provides a new cost
effective solution for providing USB Host capability into products that previously did not have the hardware resources
available.

Figure 6 - MP3 playback using VMusic2 controlled by a PIC MCU
By adding a PIC microcontroller and a few other components, the VMusic2 module can be used to playback audio
connected to the inputs on the PIC. There buttons are used to control play / pause / continue / stop / skip forward /
skip back / volume up and volume down. The Microchip PIC code is written using the standard VDAP music playback
commands, and is available on request from FTDI.
