Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range operation (-40°C to +85°C). Confirm the package type FG900 corresponds to the required pin count and thermal characteristics. Ensure authenticity through authorized distributors to avoid counterfeit components. Check for RoHS compliance status if environmental regulations apply to the deployment environment.

Field Programmable Gate Array Selection Notes

Select this component when moderate logic density and embedded memory are required within a cost-effective FPGA architecture. Compare against higher-end Virtex or lower-end Spartan families based on performance needs. Evaluate power consumption requirements against the 1.2V core voltage specifications. Consider the FG900 package availability and board space constraints during the initial design phase.

Field Programmable Gate Array Part Context

This part belongs to the Spartan-3A FPGA family, which bridges the gap between entry-level and mid-range programmable logic devices. It shares architectural similarities with the Spartan-3E but offers increased capacity and enhanced features. The family is designed for applications requiring reliable, scalable logic solutions without the complexity of high-end FPGAs.

Field Programmable Gate Array Replacement Considerations

Direct replacements may include other Spartan-3A variants with similar gate counts or I/O configurations. Cross-reference pinouts and electrical specifications carefully when considering alternative packages or speed grades from the same family.
