Power-On Power Supply Requirements
Xilinx FPGAs require a certain amount of supply current
during power-on to insure proper device operation. The
actual current consumed depends on the power-on ramp
rate of the power supply.
The V
on no faster than 100
on is defined as: 0 V

Power supplies can be turned on in any sequence, as long
as V
If any V
draws up to 600 mA, worst case, until the V
on
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.
Once initialized and configured, use the power calculator to
estimate current drain on these supplies.
