KC705 Evaluation Board
53
UG810 (v1.3) May 10, 2013
Feature Descriptions
shows the power connector J49, power switch SW15 and indicator LED DS22.
The KC705 Evaluation Kit provides the adapter cable shown in
for powering
the KC705 board from the ATX power supply 4-pin peripheral connector. The Xilinx part
number for this cable is 2600304, and is equivalent to Sourcegate Technologies part number
AZCBL-WH-1109-RA4.
FPGA_PROG_B Pushbutton SW14 (Active-Low)
[
, callout
Switch SW14 grounds the FPGA's PROG_B pin when pressed. This action initiates an
FPGA reconfiguration. The FPGA_PROG_B signal is connected to FPGA U1 pin K10.
See
7 Series FPGAs Configuration User Guide
for further details on configuring the
7 series FPGAs.
