Notes:
1. The numbers in this table are based on the conditions set forth in Table 4. Quiescent supply current is measured with all I/O drivers in a
high-impedance state and with all pull-up/pull-down resistors at the I/O pads disabled. For typical values, the ambient temperature (T_A) is
25°C with V_CCINT = 1.2V, V_CCO = 2.5V, and V_CCAUX = 2.5V. The FPGA is programmed with a "blank" configuration data file (i.e., a design
with no functional elements instantiated). For conditions other than those described above, (e.g., a design including functional elements),
measured quiescent current levels may be higher than the values in the table.
2. There are two recommended ways to estimate the total power consumption (quiescent plus dynamic) for a specific design: a) The
Spartan-3E Web Power Tool, a future web-based application, provides quick, approximate, typical estimates, and does not require a netlist
of the design. b) XPower, which will be included in a future release of the Xilinx development software, takes a netlist as input to provide
more accurate maximum and typical estimates.
3. The maximum numbers in this table indicate the minimum current each power rail requires in order for the FPGA to power-on successfully.
4. All typical quiescent current values are early estimates.
