Notes:
1.
Recommended maximum voltage drop for VCCAUX is 10 mV/ms.
2.
Configuration data is retained even if VCCO drops to 0V.
3.
VBATT is required only when using bitstream encryption. If battery is not used, connect VBATT to either ground or VCCAUX.
4.
Includes VCCO of 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V.
5.
The configuration supply voltage VCC_CONFIG is also known as VCCO_0.
6.
A total of 100 mA per bank should not be exceeded.
