7 Series FPGAs

[trapygin]

Please help me. I read user guides on 7 Series FPGAs and I don t understand one moment:

 on which devices should be marking speed grade.

In user guides i read that this line is not marked on some devices. Refer to the bar code for device speed grade and

temperature range information.

Hi @trapygin

As described in UG475, the 4^th line of the device marking (which contains the FPGA speed grade) is not found on some of the newer Xilinx FPGAs.  Instead, Xilinx is adding a bar code to “to improve device-level traceability, delivery support, and supply chain safety”.  This bar code contains the device speed grade and temperature information, which can be read using the web tool described in Xilinx document XTP424.

Cheers,
Mark

Maybe you can explain, from which year all information on all circuits in bar code?

@trapygin

Xilinx document AR67513, which was updated on 11/19/2018, says that the barcodes were available in Jan2017. 

AR67513 also says, "Customers can email 2dbarcode@xilinx.com with a device barcode marking image and receive an automated email response with device data."   This is a good way to check if you have an authentic FPGA from Xilinx.
