| |
− | Platform Cable USB (Figure 1) is a high-performance download cable attaching to user hardware for the purpose of programming or configuring any of the following Xilinx devices:
| |
− | *ISP Configuration PROMs
| |
− | *CPLDs
| |
− | *FPGAs
| |
− | Platform Cable USB attaches to the USB port on a desktop or laptop PC with an off-the-shelf Hi-Speed USB A-B cable. It derives all operating power from the hub port controller. No external power supply is required. A sustained slaveserial FPGA configuration transfer rate of 24 Mb/s is possible in a Hi-Speed USB environment. Actual transfer rates can vary if bandwidth of the hub is being shared with other USB peripheral devices.
| |
| | | |
− | Device configuration and programming operations using Platform Cable USB are supported by iMPACT download software using Boundary-Scan (IEEE 1149.1 / IEEE 1532), slave-serial mode, or serial peripheral interface (SPI). Platform Cable USB supports indirect (via an FPGA IEEE 1149.1 [JTAG] port) programming of select flash memories including the Platform Flash XL configuration and storage device. Target clock speeds are selectable from 750 kHz to 24 MHz.

− | Platform Cable USB attaches to target systems using a 14-conductor ribbon cable designed for high-bandwidth data transfers. An optional adapter that allows attachment of a flying lead set is included for backward compatibility with target systems that do not use the ribbon cable connector.
