Please help me about XC9572-15PCG84C.

Hi, I am Myoungsu Kim, a small electronic parts dealer in South Korea.

I am trying to help one of my customers.

He uses In-System Programmable CPLD, XC9572-15PCG84C (with 3.3Volt).

Please recommend me a solution, which can replace XC9572-15PCG84C with minimum changes.

@mskim2294 According to PDN there is no direct replacement available for XC9572-15PCG84C. I would recommend you to please contact sales and check if they have any replacement with least changes.

Pratham,

 

Thank you for your kind notice.

I read the EOL notice and knew there is no direct replacement.

I tried the way,"contacting local sales channel" for other makers...but it took too much time and sometimes I felt disregarded...

I hope I can get some solution from the wise men here.

 

Again, thank you!

There is no other solution could be proposed here with minimal changes.

your customer has to make changes in the pcb to accomodate the latest cpld(might need xc2c128 coolrunner) and try to re-implement the xc9572 desing in ise tool for the new cpld selected

It's pretty nasty ... but you could get a TQ100 XC9572XL (very similar to the XC9572, but it requires 3.3V; since your application is 3.3V anyway this will be fine) and do a tiny PCB that converts the TQFP100 footprint to PCG84. It's pretty nasty, but if this device is valuable enough to be spending significant time/effort on then that might be the way to go. It'd greatly improve upgrade options, and (someone correct me if I'm wrong) I think you can even get away with using the same bitstream.

I'm pretty sure you need to generate a new bitstream when moving from XC9500 to XC9500XL series parts even for the same size and package.  On the other hand, the fitter should find the same solution, so there would be very little risk in converting the design.
