The numbers in this table are based on the conditions set forth in
in a high-impedance state and with all pull-up/pull-down resistors at the I/O pads disabled. Typical values are characterized using
devices with typical processing at ambient room temperature (T
Maximum values are the production test limits measured for each device at the maximum specified junction temperature and at
maximum voltage limits with V
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, the use of DCI standards, etc.), measured quiescent current levels may be different than the
values in the table. Use the Web Power Tool or XPower for more accurate estimates. See Note 2.
There are two recommended ways to estimate the total power consumption (quiescent plus dynamic) for a specific design: a) The
Spartan-3 Web Power Tool at
require a netlist of the design. b) XPower, part of the Xilinx ISE development software, uses the FPGA netlist as input to provide more
accurate maximum and typical estimates.
The maximum numbers in this table also indicate the minimum current each power rail requires in order for the FPGA to power-on
successfully, once all three rails are supplied. If V
