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. This is the time required to reach the nominal
power supply voltage of the device1 from 0V. The fastest ramp rate is 0V to nominal voltage in 2 ms, and the slowest allowed
ramp rate is 0V to nominal voltage in 50 ms. For more details on power supply requirements, see XAPP158 on
DC Input and Output Levels
Values for VIL and VIH are recommended input voltages. Values for IOL and IOH are guaranteed over the recommended
operating conditions at the VOL and VOH test points. Only selected standards are tested. These are chosen to ensure that
all standards meet their specifications. The selected standards are tested at minimum VCCO with the respective VOL and
VOH voltage levels shown. Other standards are sample tested.

Notes:
1.
Ramp rate used for this specification is from 0 - 1.8 V DC. Peak current occurs on or near the internal power-on reset threshold and
lasts for less than 3 ms.
2.
Devices are guaranteed to initialize properly with the minimum current available from the power supply as noted above.
3.
Larger currents might result if ramp rates are forced to be faster.
