The USB 2.0 cable is not included in the kit. A USB Type A to USB Type B interface cable is
required for ML555 to PC serial communications over the USB interface.
The Platform USB programming cable, included with the Virtex-5 LXT ML555 FPGA
Development Kit for PCI Express, PCI-X, and PCI interfaces, contains a USB Type A to USB
Type B interface cable. If the Platform USB programming cable is not being used to
program devices on the ML555 board, the cable could be used for USB communications
between the ML555 board and a host computer.
The ML555 board contains a CP2102 USB to UART bridge circuit from Silicon
Laboratories. The USB 2.0 interface is provided external to the board while the FPGA
utilizes a UART interface. The USB interface cable is not provided with the ML555
development kit. USB interface cables are available at many office supply and computer
peripheral consumer stores. A USB B-to-A cable is required to interface a PC USB “A” port
to the ML555 USB “B” port.
Royalty-free Virtual COM Port (VCP) device drivers are provided by Silicon Laboratories
to permit the CP2102 USB to UART bridge to appear as a COM port to the personal
computer (PC) application. The UART interface side of the bridge implements all RS-232
interface signals, including control and handshaking signals. The VCP device driver must
be installed on the PC prior to attempting to establish communications with the ML555
board. The device driver is on the ML555 CD-ROM. The driver allows the PC USB port to
