VDIP2 Vinculum VNC1L Module Datasheet Version 1.0

Clearance No.: FTDI# 145

1 Introduction

The VDIP2 module is an MCU to embedded USB host controller development module for the VNC1L I.C.

device.The VDIP2 is supplied on a PCB designed to fit into a 40 pin DIP socket, and provides access to

the UART, parallel FIFO, and SPI interface pins on the VNC1L device, via its AD and AC bus pins. All other

Vinculum I/O pins are also accessable. Not only is it ideal for developing and rapid prototyping of VNC1L

designs, but also an attractive quantity discount structure makes this module suitable for incorporation

into low and medium volume finished product designs.

The Vinculum VNC1L is the first of FTDI’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 is

available in Pb-free (RoHS compliant) compact 48-Lead LQFP package.
