Vinculum (VNC1L) - USB Host/Slave Controller IC

USB Host/Slave controller IC.

* Previous generation device, not recommended for new designs

* Previous generation device, Vinculum II (VNC2) is recommended for new designs

VNC1L USB Host Controller IC's 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.
