Notes to Table 1–3:
(1) In Stratix III devices, V_CCL can also be 1.1 V, while V_CC and V_{CCD_PLL} are 1.1 V. In HardCopy III devices, all three supplies are 0.9 V.
(2) In Stratix III devices, this power supply is also used for programmable power technology.
(3) V_CCPD is either 2.5 V or 3.0 V. For a 3.0-V I/O standard, V_CCPD = 3.0 V. For a 2.5 V or lower I/O standard, V_CCPD = 2.5 V.
(4) In HardCopy III devices, this power supply is not used.
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 enters user mode with
no inputs/outputs toggling and no activity in the device. Since these currents vary
largely with the resources used, use the Excel-based Early Power Estimator (EPE) to
get supply current estimates for your design.
