VNC1L Vinculum USB Host Controller IC

The VNC1L, is the first device to be released from FTDI's new Vinculum range of Slave/Host USB Controllers.

Vinculum now makes it even easier to integrate USB functionality into your products and with the VNC1L device you can implement USB Host Controller functionality in no time at all.

As you would expect the device features FTDI's award winning, tried and tested, firmware which is stored on-board in flash and can easily be updated ensuring your products are future proof.

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

VNC1L brings cost effective USB Host capability to products that previously did not have the hardware resources available.  We anticipate that these devices will be especially popular for adding USB Flash drive connectivity to a wide range of consumer and industrial products.  As VNC1L comes complete with FTDI's in-house developed firmware, there are no USB software stacks to license, indeed, no knowledge of USB is required to use these devices.

With the VNC1L you can now connect USB Flash Drives to MCU's via a UART or parallel FIFO interface or connect Digital Cameras, PDA's and other USB slave peripherals to USB Flash Keys and other USB slave devices in stand-alone mode.

Comprehensive Development Support

Custom PID service
For volume applications Alpha Micro can provide a Product Identifier (PID) under the FTDI "umbrella scheme" that can be used to personalise a design based on the FT232Bx so that your end user will see your product name in the Windows Install Wizard for extra brand awareness.

There is an added benefit that the driver is tagged to your hardware and cannot be used by other devices. This feature can only be used with FTDI chips, the Vendor ID (VID) must remain untouched. Please contact our sales team for more information on this facility.

Customers should use MPROG to program this feature and any other changes to the default settings within the EEPROM (which must be fitted if this feature is required). MPROG is free to use and performs the programming tasks over the USB.
