FTDI, available through Glyn High-Tech Distribution, has released the VDIP1 module for its Vinculum family of embedded USB Host Controller devices. The VDIP1 module is an MCU to embedded USB host controller development module for the Vinculum VNC1L-1A IC device.
The VDIP1 is supplied on a PCB designed to fit into a 24 pin DIP socket, and provides access to the UART, parallel FIFO, and SPI interface pins on the VNC1L-1A device, via its AD and AC bus pins.
It is ideal for developing and rapid prototyping of VNC1L-1A designs, and the module is suitable for incorporation into low and medium volume finished product designs.
Key VDIP1 features include jumper selectable UART, SPI or FIFO MCU Interfaces, USB A type socket to interface with USB peripherals, 2nd USB Interface available via module pins if required, single 5V supply input, auxiliary 3.3V/200mA power output to power external logic, Power Good and Traffic Indicator LEDs, and RESET# and PROG# signals allow device programming via the UART interface if required. VNC1L firmware on the VDIP1 can be programmed or updated via USB Flash disk or via UART / parallel FIFO / SPI interface.
The Vinculum VNC1L-1A is the first of FTDI’s Vinculum family of embedded USB host controller integrated circuit devices. Not only is it able to handle the USB Host Interface, and data transfer functions, but owing to the inbuilt MCU and embedded Flash memory, Vinculum can encapsulate the USB device classes as well.
When interfacing to mass storage devices such as USB Flash drives, Vinculum also transparently handles the FAT File structure communicating via UART, SPI or parallel FIFO interfaces via a simple to implement command set. Vinculum provides a new cost effective solution for providing USB Host capability into products that previously did not have the hardware resources available. The VNC1L-1A is available in Pb-free (RoHS compliant) compact 48-Lead LQFP package.
