For device operation, the maximum signal voltage (V
There is approximately 100 mV of hysteresis on inputs using LVCMOS33 and LVCMOS25 I/O standards.
All Dedicated pins (PROG_B, DONE, SUSPEND, TCK, TDI, TDO, and TMS) draw power from the V
LVCMOS33 standard depending on V
using these pins as part of a standard 2.5V configuration interface, apply 2.5V to the V
throughout configuration.
For information on PCI IP solutions, see www.xilinx.com/pci. The PCI IOSTANDARD is not supported on input-only pins. The PCIX
IOSTANDARD is available and has equivalent characteristics but no PCI-X IP is supported.
