DC Characteristics
This section lists the input pin capacitances, on-chip termination tolerance, and
hot- socketing specifications.
Supply Current
Standby current is the current the device draws after the device is configured with no
inputs/outputs toggling and no activity in the device. Because these currents vary
largely with the resources used, use the Excel-based Early Power Estimator (EPE) to
get supply current estimates for your design.
Table 1–4 lists supply current specifications for V_{CC_CLKIN} and V_CCPGM. Use the EPE to get
supply current estimates for the remaining power supplies.

Notes to Table 1–5:
(1) This value is specified for normal device operation. The value may vary during power-up. This applies for all V_CCIO
settings (3.3, 3.0, 2.5, 1.8, 1.5, and 1.2 V).
(2) The 10-A I/O leakage current limit is applicable when the internal clamping diode is off. A higher current can be
observed when the diode is on.
