Shenzhen, ChinaFuture Technology Devices International Ltd. (FTDI) released a USB prototyping module dubbed the VDIP2 that is based on its Vinculum VNC1L embedded USB host controller.
The VDIP2 is designed to accelerate VNC1L designs, and integrate into low-volume finished products. Supplied to fit a 40 pin DIP header, VDIP2 provides access to all the UART, parallel FIFO and SPI interface pins. The device is equipped with two vertically mounted USB type-A sockets.
The module requires a single 5V DC supply input and provides an auxiliary 3.3 V output for external logic. The board is equipped with two LEDs that indicate power-on and USB traffic. Program and firmware updates can be performed by using a USB flash disk or through one of the other device interfaces.
The VNC1L IC provides all USB host interfaces and data transfer functions. With a built-in microcontroller and flash memory, VNC1L encapsulates the popular USB device classes. When using storage devices, such as USB flash drives, the Vinculum Disk and Peripheral Interface (VDAP) instruction set provides a convenient method of handling file, directory and file allocation table (FAT) commands.
