Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Ensure that any acquired units are verified for authenticity and storage history due to the end-of-life status.

Selection Notes

Designers requiring this specific pin count and logic density must account for the discontinuation status. When selecting alternatives, verify compatibility with existing firmware and physical footprint constraints. Consider modern CPLD replacements that offer similar I/O counts and voltage ranges while ensuring long-term supply stability.

Part Context

The XCR3256XL-10FT256I belongs to the CoolRunner-XPLA3 series, which bridges the gap between complex FPGAs and simple PLDs. This series is characterized by its low power consumption and fast performance relative to traditional GALs. The '10' suffix indicates the speed grade, while 'FT256' denotes the 256-pin FBGA package.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model are not available in the provided documentation. Due to the discontinued status, engineers should consult official AMD replacement guides or evaluate generic CPLD equivalents with matching I/O and logic resources.
