Power-On/Off Power Supply Sequencing
The recommended power-on sequence is V_CCINT, V_{CCINT_IO}/V_CCBRAM, V_CCAUX/V_{CCAUX_IO}, and V_CCO to
achieve minimum current draw and ensure that the I/Os are 3-stated at power-on. The recommended
power-off sequence is the reverse of the power-on sequence. If V_CCINT and V_{CCINT_IO}/V_CCBRAM have the
same recommended voltage levels, they can be powered by the same supply and ramped simultaneously.
V_{CCINT_IO} must be connected to V_CCBRAM. If V_CCAUX/V_{CCAUX_IO} and V_CCO have the same recommended
voltage levels, they can be powered by the same supply and ramped simultaneously. V_CCAUX and V_{CCAUX_IO}
must be connected together. V_CCADC and V_REF can be powered at any time and have no power-up
sequencing requirements.
The recommended power-on sequence to achieve minimum current draw for the GTY transceivers are
V_CCINT, V_MGTAVCC, V_MGTAVTT OR V_MGTAVCC, V_CCINT, V_MGTAVTT. There is no recommended sequencing for
V_MGTVCCAUX. Both V_MGTAVCC and V_CCINT can be ramped simultaneously. The recommended power-off
sequence is the reverse of the power-on sequence to achieve minimum current draw.
If these recommended sequences are not met, current drawn from V_MGTAVTT can be higher than
specifications during power-up and power-down.
Power Supply Requirements
Table 6 shows the minimum current, in addition to I_CCQ, that are required by Virtex UltraScale+ FPGAs for
proper power-on and configuration. If the current minimums shown in Table 5 and Table 6 are met, the
device powers on after all supplies have passed through their power-on reset threshold voltages. The
device must not be configured until after V_CCINT is applied. Once initialized and configured, use the Xilinx
Power Estimator (XPE) tools to estimate current drain on these supplies.
