Hi, We have noticed that the Xilinx CPLD XC95144XL-10TQG100I part will become obsolete in the year 2020. Could you recommend us a CPLD from Intel, please? Additionally, could you provide us the longevity plan for the alternative part, please?

Max II and Max V are older CPLDs that are still supported by the Older versions of Quartus tools.

Max 10 FPGAs are kind of newer devices which are supported by the latest software releases.

I do not have the EOL data for these devices, but you can visit this link to check for PDNs (Product Discontinue Notifications) from Intel. This will be regularly updated by Intel for their products.
