Notes:
1. With no output current loads, no active input pull-up resistors, all I/O pins are 3-state and floating.
2. If DCI or differential signaling is used, more accurate values can be obtained by using the Power Estimator or XPOWER™.
3. Data are retained even if VCCO drops to 0 V.
4. Values specified for quiescent supply current parameters are Commercial Grade. For Industrial Grade values, multiply Commercial
Grade values by 1.25.
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.
The VCCINT, VCCAUX, and VCCO power supplies shall each
ramp on no faster than 200 µs and no slower than 50 ms.
Ramp on is defined as: 0 VDC to minimum supply voltages.
Table 5 shows the minimum current required by Virtex-II
devices for proper power on and configuration.
Power supplies can be turned on in any sequence.
If any VCCO bank powers up before VCCAUX, then each bank
draws up to 300 mA, worst case, until the VCCAUX powers
on(1). This does not harm the device. If the current is limited
to the minimum value above, or larger, the device powers on
properly after all three supplies have passed through their
power on reset threshold voltages.
Once initialized and configured, use the power calculator to
estimate current drain on these supplies.
Notes:
1. The 300 mA is transient current (peak); it eventually
disappears even if VCCAUX does not power up.
