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.

Notes:
Table 5 shows the minimum current required by Virtex-II
devices for proper power on and configuration.
1. The 300 mA is transient current (peak); it eventually
disappears even if VCCAUX does not power up.
Power supplies can be turned on in any sequence.
