Pinout Comptatibility of Spartan 6 FPGAs

Dear Sir or Madam,

Are XC6SLX45T-3FGG484C and XC6SLX100T-3FGG484C FPGAs pin to pin compatible? We have a PCB design that we use XC6SLX45T-3FGG484C FPGA already and we would like to know if we replace that FPGA with a XC6SLX100T-3FGG484C if there will be full compatibility.

Best regards,

Panagiotis Vagiannis

Have a look at page 17
https://www.xilinx.com/support/documentation/selection-guides/cost-optimized-product-selection-guide.pdf#S6

"The footprint compatibility range is indicated by shading per column."

BUT ,

a) you will have to re compile the code for the new part,
b) you need to check the pin out yourself, different chips in the same package, drop / add pins, In particular, the power pins all need to be connected,
