Power-On Power Supply Requirements
Xilinx FPGAs require a minimum rated power supply current
capacity to insure proper initialization, and the power supply
ramp-up time does affect the current required. A fast
ramp-up time requires more current than a slow ramp-up
time. The slowest ramp-up time is 50 ms. Current capacity
is not specified for a ramp-up time faster than 2 ms. The cur-
rent capacity varies linealy with ramp-up time, e.g., an
XQ4036XL with a ramp-up time of 25 ms would require a
capacity predicted by the point on the straight line drawn
from 1A at 120 µs to 500 mA at 50 ms at the 25 ms time
mark. This point is approximately 750 mA .

Notes:
1. The XC4085XL fast ramp-up time is 5 ms.
2. Devices are guaranteed to initialize properly with the minimum current listed above. A larger capacity power supply may result in a
larger initialization current.
3. This specification applies to Commercial and Industrial grade products only.
4. Ramp-up Time is measured from 0V to 3.6V . Peak current required lasts less than 3 ms, and occurs near the internal power
