Field Programmable Gate Array Procurement Notes

Verify the specific suffix code to confirm the industrial temperature range (-40°C to +85°C) and RoHS compliance status. Ensure the package type matches the TQFP-144 footprint requirements for your PCB design. Confirm that the source provides original manufacturer documentation to avoid counterfeit components, as this part is from an established product line.

Field Programmable Gate Array Selection Notes

Select this component when a balance of moderate logic density and low cost is required for entry-level FPGA designs. Consider the Spartan-3 family if Flash-based configuration is preferred over SRAM-based alternatives to simplify board layout by removing external configuration chips. Evaluate power consumption constraints against the device's active and standby current specifications.

Field Programmable Gate Array Part Context

This model is part of the Xilinx Spartan-3 FPGA family, designed for cost-sensitive applications requiring reliable programmable logic. The Spartan-3 series introduced Flash technology to the mainstream FPGA market, offering advantages in security and simplicity compared to previous generations. It serves as a foundational platform for various embedded logic solutions.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are limited due to architectural differences. Potential upgrades include the Spartan-3A or Spartan-3E series for similar form factors, though parameter adjustments may be necessary. For modern equivalents, consider the Artix-7 or Kinex UltraScale+ families, which require schematic and firmware redesigns.
