*Note: The Imax value shown above table is the maximum value when the desired FPGA is used in the majority of applications. There may be cases in which the required current is higher or lower depending on your clock frequencies and your particular usage case. For your exact current requirements, go to the power estimator spreadsheet for your FPGA.
