1.1 Introduction
The VF2F2 is a reference design for the Vinculum VNC1L . It is designed as a stand alone application which allows
for the back up of files from a digital camera onto a USB Flash disk. The project is also available from FTDI as
an evaluation kit. This datasheet describes the VF2F2 reference design and evaluation kit, as well as the VNC1L
firmware (VDFC) which it uses.
The VF2F2 illustrates how to construct a file backup device for a digital camera with USB Mass storage class
interface. At the push of a button, all the picture files on the camera are copied to a unique folder on a USB Flash disk
so that the digital camera memory can be re-used to take further pictures. This is an ideal accessory for digital camera
users who wish to backup their photos on the road without having to carry a notebook PC, or for people who want to
share or swap their photos without requiring a card reader. The VF2F2 is powered by two AAA size alkaline batteries.
In addition this reference design and evaluation kit could be used with other USB mass storage class devices such as
MP3 players, or even for copying files directly from one USB flash disk onto another.
The Vinculum VNC1L is the first of F.T.D.I.’s Vinculum family of Embedded 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 File 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. The VNC1L-1A is available in Pb-free (RoHS compliant) compact 48-Lead LQFP package.
