Difference between XC7Z020 and XQ7Z020

[seb_pdr]

Hello,

I would like to know the difference between the XC7Z020 and XQ7Z020 devices.

Is it only the lead concentration in the solder interface ?

And is the XQ7Z020 radiation hardened ?

Thanks by advance.

Best regards

Hi @seb_pdr

Main difference is temperature range between XC7Z020 and XQ7Z020 devices

For more details check DS187 (v1.20.1).

XQ7Z020 devices are defense grade FPGA's.

Seb_PDR,

I highly recommend looking at the Product Brief for the 7-series defense grade first and then delve into the overview data sheet for more detail. The brief should contain a break down of the differences between XC and XQ and what sets the XQ apart. I'll list the main ones here for now:

• Full range extended temperature testing

• Mask set control

• Full compliance with MIL-PRF-38535 Pb content standards

• Longer-term availability • Anti-counterfeiting features

• Ruggedized & Leaded packaging option

• Available information assurance

• Available anti-tamper methodology

Thank you for your answer.

I asked this question because I have found some radiation data on the XC7Z020 in scientific publications and I would like to know if they are applicable on the XQ7Z020.

Could you confirm this ? Are the mask layout, fabrication process, etc the same for both components ?

Thanks by advance

Seb_pdr,

Aside from the difference or pluses listed above which are mostly environmental robustness for which they need to be in an "Mil/Aero" conditions, they are the same silicon... If you need more convincing, they use the same data sheet...

Thank you Tezz for your answer.

It is very helpuful.
