Product Obsolete/Under Obsolescence
D.C. Characteristics Over Recommended Operating Conditions
Power-0n 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 2ms. The current capacity
varies linealy with ramp-up time, e.g., an XC4036XL 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.
Devices are guaranteed to initialize properly with the minimum current listed above. A larger capacity power supply may
result in a larger initialization current.
This specification applies to Commercial and Industrial grade products only.
Ramp-up Time is measured from 0 VDC to 3.6 VDC. Peak current required lasts less than 3 ms, and occurs near the
internal power on reset threshold voltage. After initialization and before configuration, ICCmax is less than 10 mA.
