Introducing the Vinculum VNC1L USB Host Controller

Vinculum is the brand name for the new family of USB Host Controller ICs devices from FTDI.
The Vinculum family of devices allow the implementation of USB host controller functionality within products, thus saving development time and costs by using FTDI's tried and tested firmware programmed into internal, easily upgradeable Flash memory.

The VNC1L is the first of FTDI’s Vinculum family of Embedded USB host controller integrated circuit devices. Vinculum can also encapsulate certain USB device classes handling the USB Host Interface and data transfer functions using the in-built MCU and embedded Flash memory. When interfacing to mass storage devices, such as USB Flash drives, Vinculum transparently handles the FAT File Structure using a simple to implement command set.
Vinculum provides a cost effective solution for introducing USB host capability into products that previously did not have the hardware resources to do so.
The VNC1L has a Combined Interface which interfaces a controlling application with the Command Monitor. The combined interfaces are UART, Parallel FIFO and SPI.


LQFP-48 Package Parameters

VNC1L is supplied in a RoHS Compliant 48 pin LQFP package as standard. The LQFP-48 package is lead (Pb) free and uses a ‘green’ compound. This package has a 7.00mm x 7.00mm body (9.00 mm x 9.00 mm including pins). The pins are on a 0.50 mm pitch.
