Hi,

            I am using the xc7k355t-3ffg901e device in my design. I need the maximum total power dissipation of the device.

thanks,

jeyalakshmi

The power requirements for any FPGA design are dependent on the design that is downloaded into the device.  If you have a single input/ouput it will have minimal current requirements if you are implementing a 400G Ethernet switch it will have much higher power requirements.

The Xilinx Power Estimator, XPE, spreadsheet and the Xilinx Power Analyzer, XPA, tool can be used to estimate your power requirements based on your design.

j,

With FPGA devices, what you put in them, determines the power.  So, I have to ask you:  what are going to do?

If you answer that, then you can also answer the total power, by using the power estimator:

It is possible to place a design in the part, that will destroy it (melt it down).  Don't do that.

Consult the absolute maximum ratings in the data sheet for where, if exceeded, damage may result, and consider the recommended operating specification ranges for where you should target your design to stay within.
