™ Future Technology Devices International Ltd. ™ VDrive2 Vinculum VNC1L Module Copyright © Future Technology Devices International Ltd. 2007 / Page  1. Introduction and Features 1.1 Introduction The VDrive2 module provides an easy solution for adding a USB Flash disk interface to an existing product. Only four signal lines plus 5V supply and ground are required to be connected. Using the Vinculum VDAP firmware the VNC1L’s I/O interface can be selected between the serial UART or SPI using the on-board jumper pins. 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 finished product designs. The VDrive2 is ideal for commercial products such as domestic goods, set top box, etc., as well as industrial products such as data loggers, software upgradable products, etc. The Vinculum VNC1L is the first 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 file structure communicating via UART, SPI or parallel FIFO interfaces via a simple to implement command set. Vinculum provides a new cost
