Obsolete device
XC9572XL replacement options
The AMD Xilinx XC9572XL has been discontinued by the manufacturer. There are two ways forward, and for most people reading this the first one is the answer: keep the design and source the part. Changing device means a board revision, so it is only worth it if you are redesigning anyway.
What the manufacturer says
AMD Xilinx's discontinuation notice lists no direct replacement for all 52 XC9572XL parts it covers. Where the manufacturer offers nothing equivalent, the remaining supply is the only way to keep the board unchanged.
From the manufacturer's discontinuation notice: Product Discontinuation Notice for XC9500XL, CoolRunner XPLA 3, CoolRunner II, Spartan II,

A different package or speed grade of the same device is the closest thing to a like-for-like change: the silicon is the same, so only the footprint or timing differs. It still needs checking against your board.
Substitutes listed by distributors
Parts distributors list as substitutes for the XC9572XL. This is what the trade buys instead — not a manufacturer equivalence, and some are other vendors' silicon entirely. Check any of them against your design.

What to check before changing device
Footprint and pinout
Ball count, pitch and pin assignment all differ between families. A new device means a new layout.
I/O voltages and banks
Supported I/O standards, bank voltages and the number of banks change between generations.
Core and I/O supplies
Newer devices usually run a lower core voltage and need a different power tree.
Configuration
Flash type, configuration mode and boot timing are family-specific.
Tools and IP
The design has to be rebuilt in the current toolchain, and IP cores may need replacing or re-licensing.
Temperature and lifetime
Check the grade you need exists, and how long the new family is expected to stay in production.
Where a design cannot be revised — certified equipment, long-life industrial and defence builds — sourcing the original is normally the cheaper route, even at obsolete pricing.
