Hi,

I am developping an fpga board based on spartan 6 LX25 and I am looking for bank power suppply.

My question is, is it possible to choose the bank voltage ?

For example, if I would like to use only 3.3V device around my fpga, bank0 to 3 can support 3.3V power supply ?

Thank you

bye
 

Have you checked the specs of your device in the datasheet?
 

Hi,
For the LX25 you have 4 I/O banks. Each bank has its own power supply, which is the VCCO pins. If you will connect the pins of bank 0 for example to 3.3 V devices then you should supply bank 0 VCCO_0 pins using a 3.3 V supply.
 
Thanks for your responses

I think you should learn to check the datasheet of your device and if you can't find something there then ask the forums.
Are you willing to simply rely on a reply posted in a forum?
And what if it is not correct, would you jeopardize damaging your device?

Don't worry about my abality to read a datasheet.
I marked it solved because I received an other response from Xilinx itself. You can choose io bank power supply from 1.2, 1.8, 2.5 or 3.3V depending on your peripherals.

Regards
