Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers due to end-of-life status. Confirm lot codes and traceability documentation to ensure compliance with quality standards. Check for moisture sensitivity level handling requirements prior to assembly. Validate pinout compatibility with existing board layouts during procurement planning.

Field Programmable Gate Array Selection Notes

Compare against newer FPGA families for improved power efficiency and feature sets if long-term availability is required. Evaluate pin count requirements carefully as the 676-ball package limits maximum I/O expansion compared to larger footprints. Consider thermal management solutions given the density of the Spartan-3A architecture in this specific package type.

Field Programmable Gate Array Part Context

This part belongs to the Spartan-3A series, an SRAM-based FPGA line designed for cost-sensitive applications. It succeeded earlier Spartan-3 models with enhanced performance and lower power consumption. The series targets general-purpose logic applications where moderate complexity meets budget constraints.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitutes include LFE3-35EA-6FN676C from Lattice Semiconductor and T55F676C from Efinix. Verify pin-to-pin compatibility and configuration file formats before substitution.
