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