The VNC1L-1A USB Host Controller not only handles the USB Host Interface and data transfer functions but owing to the inbuilt 8/32-bit MCU and embedded Flash memory the VNC1L-1A encapsulates the USB device classes as well. When interfacing to mass storage devices such as USB Flash drives, VNC1L-1A also transparently handles the FAT file structure communicating via UART, SPI or parallel FIFO interfaces via a simple-to-implement command set. The VNC1L-1A device features two USB ports which can be individually configured by firmware as Host or Slave ports.

VNC1L-1A brings cost effective USB Host capability to products that previously did not have the hardware resources available. This device are anticipated to be especially popular for adding USB Flash drive connectivity to a wide range of consumer and industrial products. The VNC1L-1A comes complete with FTDI's in-house developed firmware, no knowledge of USB is required to use this device.

The VNC1L-1A device which features two USB Ports which can be individually configured by firmware as Host or Slave ports.
