Max. current consumption on Zynq-7000 power rails

Hello,

 

What is maximal current consumption on Zynq-7000 rails beyond which one can suspect a latch-up is about to start.

Sincerely,

Pavel

Hi,

I think the current consumption varies greatly depend on the different applications. Suggest to use the XPE to get a draft estimation and then leave some budget for each power rails.

Pavel_47,

 

Couple things here. First if you are interested in latchup test data see our reliability report document UG116. Second, the FPGA pins have clamp diodes so as long as you design by table 1 of the data sheet they should not get damaged. There are auxiliary requirements such as the 10mA per pin and 200mA per IO bank which should be designed to as well. For max current device can handle you can fiddle with XPE until a rail become red that should be a goo indication that you are at that device supply's max load. 

 

Regards,

T

Hi Zhik,

 

For the moment our design isn't ready yet, so it's difficult to estimate resources and clocking.

Can I find somewhere some reference designs for Zynq-7000 or Kintex and import them to XPE ?

Thanks
