Power consumption of Spartan-3A XC3SD1800A

[chethansharma]

Hello,
I wanted to know the power specification of Spartan-3
(XC3SD1800A).In the data sheet it does not speak precisely of the powe
consumption. How much is the power rating of the board? Also what,s th
maximum current the board needs or withstand -- is less than 4A sufficien
to drive the board safely? Please throw some light on the above queries.

Cheers;
Chethan

I apologize for replying without an answer, but, don't you have a
manual or datasheet for this board. Hard to believe if you don't.

I suggest that you RTFM or RTFD before you come here asking some
questions where the answers should already be supplied by the MFG.

Power consumption will vary with the FPGA build and frequency of
operation. By experience a XC3SD1800A might take between 0.25A and 4A
on the core voltage of 1.2V. Similar variations are also possible on
the Vcco input for bank voltages.

To narrow this all down try using the Xilinx Xpower tool. Even if you
don't have a finished FPGA design it can give some indication fo what
you might need.
