Electrical Characteristics
DC Characteristics
This section lists the supply current, I/O pin leakage current, input pin capacitance,
on-chip termination tolerance, and hot socketing specifications.
Supply Current
Standby current is the current drawn from the respective power rails used for power
budgeting. Use the Excel-based Early Power Estimator (EPE) to estimate supply
current for your design because these currents vary greatly with the resources you
use.

For more information about power estimation tools, refer to the PowerPlay Early Power
Estimator User Guide and the PowerPlay Power Analysis chapter in the Quartus II
Handbook.
