Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +125°C) against official datasheets. Confirm the package type matches the required PQFP-208 footprint. Ensure compatibility with the Spartan-3A FPGA toolchain before procurement. Cross-reference manufacturer part numbers to avoid confusion with commercial variants.

Field Programmable Gate Array Selection Notes

Select this model when industrial temperature stability is mandatory alongside moderate logic density. Compare resource utilization against Spartan-3AN or Spartan-6 families for cost-performance optimization. Verify power supply constraints align with the 1.2V core requirement. Assess I/O count needs against the available 141 pins to ensure sufficient connectivity.

Field Programmable Gate Array Part Context
