The VNC2 is the second of FTDI’s Vinculum family of Embedded dual USB host controller devices. The VNC2 device provides USB Host interfacing capability for a variety of different USB device classes including support for BOMS (bulk only mass storage), Printer, HID (human interface devices). For mass storage devices such as USB Flash drives, VNC2 also transparently handles the FAT file structure. Communication with non USB devices such as a low cost microcontroller is accomplished via either UART, SPI or parallel FIFO interfaces. The VNC2 provides a new cost effective solution for providing USB Host capability into products that previously did not have the hardware resources available. The VNC2 supports the capability to enable customers to develop custom firmware using the Vinculum II development software tool suite. The development tools support compiler, linker and debugger tools complete within an integrated development environment (IDE). The Vinculum-II VNC2 family of devices are available in 32-lead LQFP, 32-lead QFN, 48-lead LQFP, 48-lead QFN, 64-Lead lQFP and 64-lead QFN packages.
USB ’A’ type USB socket to interface with USB peripheral devices Second USB interface port accessible via module pins if required UART, parallel FIFO and SPI interfaces can be programmed to a choice of available I/O pins Single +5V supply input from DIL connectors or +5V supplied via USB VBUS slave interface or debugger module Auxiliary +3.3V @ 200mA power output to external logic Debugger interface pin available on DIL pins or via 6 way male header which interfaces to separate debugger module Firmware upgrades via UART or debugger interface pin header
