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 VCC_CLKIN and VCCPGM. Use the EPE to get

supply current estimates for the remaining power supplies.

I/O Pin Leakage Current

Table 1–5 lists Stratix III I/O pin leakage current specifications.

Bus Hold Specifications

Table 1–6 lists the Stratix III device family bus hold specifications.

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.
