Notes:
1. With no output current loads, no active input pull-up resistors, all I/O pins 3-stated and floating.
2. 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.
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 device
1
from 0 V. The fastest suggested ramp rate is 0 V to nominal voltage in 2 ms and the
slowest allowed ramp rate is 0 V to nominal voltage in 50 ms.

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.
