The numbers in this table are based on the conditions set forth in
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. Typical values are characterized using typical devices at room temperature (T
= 2.5V). The maximum limits are tested for each device at the respective maximum specified junction temperature and at maximum voltage
limits with V
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 different than the values in the table. For more accurate estimates for a specific
design, use the Xilinx® XPower tools.
There are two recommended ways to estimate the total power consumption (quiescent plus dynamic) for a specific design: a) The
Spartan-3E XPower Estimator
Analyzer uses a netlist as input to provide maximum estimates as well as more accurate typical estimates.
The maximum numbers in this table indicate the minimum current each power rail requires in order for the FPGA to power-on successfully.
