Notes:
1.
Descriptions of the symbols used in this table are as follows:
VCCO – the supply voltage for output drivers
VREF – the reference voltage for setting the input switching threshold
VIL – the input voltage that indicates a Low logic level
VIH – the input voltage that indicates a High logic level
2.
In general, the VCCO rails supply only output drivers, not input circuits. The exceptions are for LVCMOS25 inputs when VCCAUX = 3.3V range
and for PCI I/O standards.
3.
For device operation, the maximum signal voltage (VIH max) can be as high as VIN max. See Table 8.
4.
There is approximately 100 mV of hysteresis on inputs using LVCMOS33 and LVCMOS25 I/O standards.
5.
All Dedicated pins (PROG_B, DONE, SUSPEND, TCK, TDI, TDO, and TMS) draw power from the VCCAUX rail and use the LVCMOS25 or
LVCMOS33 standard depending on VCCAUX. The dual-purpose configuration pins use the LVCMOS standard before the User mode. When
using these pins as part of a standard 2.5V configuration interface, apply 2.5V to the VCCO lines of Banks 0, 1, and 2 at power-on as well as
throughout configuration.
6.
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.
