Notes:
1. Internal pull-up and pull-down resistors guarantee valid logic levels at unconnected input pins. These pull-up and pull-down resistors do not
guarantee valid logic levels when input pins are connected to other circuits.

Notes:
1. With no output current loads and no active input pull-up resistors. All I/O pins are 3-stated and floating.
2. If DCI or differential signaling is used, more accurate values can be obtained by using the Power Estimator or XPOWER.
3. Data are retained even if V_CCO drops to 0V.
4. All values shown reflect the military temperature operating range. For industrial temperature operating range values, refer to [Ref 4].
Power-On Power Supply Requirements
Xilinx FPGAs require a certain amount of supply current
during power-on to ensure proper device operation. The
actual current consumed depends on the power-on ramp
rate of the power supply.
The V_CCINT, V_CCAUX, and V_CCO power supplies shall each
ramp on no faster than 200 μs and no slower than 50 ms.
Ramp on is defined as: 0 V_DC to minimum supply voltages.
Table 35 shows the maximum current required by QPro
Virtex-II FPGAs for proper power on and configuration.
Power supplies can be turned on in any sequence.
If any V_CCO bank powers up before V_CCAUX, then each bank
draws up to 300 mA, worst case, until the V_CCAUX powers
on. This current draw does not harm the device. If the
current is limited to the minimum value above, or larger, the
device powers on properly after all three supplies have
passed through their power on reset threshold voltages.
Note: The 300 mA is transient current (peak) and eventually
disappears even if V_CCAUX does not power up
Once initialized and configured, use the power calculator to
estimate current drain on these supplies.
