Notes:
1.
The numbers in this table are based on the conditions set forth in Table 8.
2.
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 (TJ of 25°C at VCCINT = 1.2V, VCCO = 3.3V, and VCCAUX
= 2.5V). The maximum limits are tested for each device at the respective maximum specified junction temperature and at maximum voltage
limits with VCCINT = 1.26V, VCCO = 3.6V, and VCCAUX = 3.6V. The FPGA is programmed with a “blank” configuration data file (that is, a design
with no functional elements instantiated). For conditions other than those described above (for example, a design including functional
elements), measured quiescent current levels will be different than the values in the table.
3.
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-3A FPGA XPower Estimator provides quick, approximate,
typical estimates, and does not require a netlist of the design. b) XPower Analyzer uses a netlist as input to provide maximum estimates as
well as more accurate typical estimates.
4.
The maximum numbers in this table indicate the minimum current each power rail requires in order for the FPGA to power-on successfully.
5.
For information on the power-saving Suspend mode, see XAPP480: Using Suspend Mode in Spartan-3 Generation FPGAs. Suspend mode
typically saves 40% total power consumption compared to quiescent current.
