Field Programmable Gate Array Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Check for lead-free status and RoHS compliance markers on the package. Confirm the specific suffix indicates commercial temperature range and standard packaging. Request datasheets matching the exact part number to ensure functional compatibility.

Field Programmable Gate Array Selection Notes

Select this model when design requirements fit within 400K gate capacity and 896 CLBs. Consider the PQFP-208 package if surface mount BGA options are unavailable or for prototyping ease. Evaluate power consumption against Spartan-3E or Spartan-6 alternatives if lower energy usage is critical for the final application.

Field Programmable Gate Array Part Context

This component belongs to the Spartan-3 FPGA family, representing an entry-level solution in Xilinx's programmable logic portfolio. It bridges basic logic functions with moderate complexity tasks, offering a balance between cost and performance for mass-market applications compared to higher-end Virtex or Kintex series devices.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements may include other Spartan-3 variants with different speed grades or temperature ranges. For functional upgrades, consider Spartan-3A or Spartan-3E series, though software migration and resource verification are required.
