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 required
power supply voltage of the device from 0V. The current is highest at the fastest suggested ramp rate (2 ms) and is lowest
at the slowest allowed ramp rate (50 ms).
Note 1:
Devices are guaranteed to initialize properly with the minimum current listed above. A larger capacity power supply may
result in larger initialization current.
This specification applies to Commercial and Industrial grade products only. Advance information based on initial
characterization.
Ramp-up Time is measured at 0V to 3.0V. Peak current required lasts less than 3 ms and occurs near the internal power-on
reset threshold voltage.
