Functional Description
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.
