6  Power requirements 

The Power is supplied to the FM680 via the XMC Pn5 connector. Several DC-DC converters 
generate the appropriate voltage rails for the different devices and interfaces present on 
board.   

The FM680 power consumption depends mainly on the FPGA devices work load. By using 
high efficiency power converters, all care has been taken to ensure that power consumption 
will remain as low as possible for any given algorithm. 

After power up, the FM680 typically consumes 6 Watts of power. For precise power 
measurements it is recommended to use the Xilinx power estimation tools for both the Virtex-
5 and Virtex-6 FPGA devices. The maximum current rating given in the table below is the 
maximum current that can be drawn from each voltage rail in the case resources are used to 
their maximum level. 

Special precautions need to be taken to support the XMC VPOWER input, since the XMC 
standard dictates that this power supply can either be 12V or 5V. To overcome this, a voltage 
detection circuit detects whether VPOWER is 12V or 5V and enables a switching regulator or
