From booth chip´s are several different versions of the FPGA case available. Let me make a example: I have several versions of EP3C40F484I7N in front of me. All are BGA.

But the Chip´s with the chip marking 21411 V0026 V0029 are 8.04 x 7.46 mm and the chip´s with the marking 21435 V0026 V0029 are 7.56 c 6.99 mm. Because this is a medical device with a very special cooling solution this is a BIG problem! Furthermore the size of the chip cover is different. Then a further analysis did come to the result that chip marking 21411 V0026 V0029 has gold wire bonds and the marking 21435 V0026 V0029 has cooper. Furthermore there are more differences. And the order code was the same!!! I need a way to identify the different chip versions before i order theme so that i get the right version.

Hope this clarifies my problem.

Good morning

There are so many Intel Support technician in this forum. Is there really nobody who has a list about the different cases and order codes for EP3C40F484I7N und EP4CE55F23C8N?

Mechanical differences as the one have explained make a big difference in devices who require advanced certification (like automotive or medical). They have a direct impact in thermal / cooling characteristics. Also the use of cooper wire instead of gold for the internal bonding changes some electrical characteristics. I can live with both - but i need to have a order information that identifies the version of the chips I'm getting so that i can control the chip version in manufacturing. I can´t order the chips by there serial number...

I hope that soon someone will come up with some useful information.
