Notes:
1. Typical values are specified at nominal voltage, 25°C.
2. For the I/O banks with a V_CCO of 1.8V and separated V_CCO and V_{CCAUX_IO} power supplies, the I_L maximum current is 70 µA.
3. This measurement represents the die capacitance at the pad, not including the package.
4. Maximum value specified for worst case process at 25°C.
5. I_BATT is measured when the battery-backed RAM (BBRAM) is enabled.
6. If VRP resides at a different bank (DCI cascade), the range increases to ±15%.
7. VRP resistor tolerance is (240Ω ±1%)
8. On-die input termination resistance, for more information see the UltraScale Architecture SelectIO Resources User Guide
(UG571).
