Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range compliance when sourcing replacements. Confirm pin compatibility with existing PCB footprints, as PQFP packages have distinct lead dimensions compared to other form factors. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability for critical deployments.

Field Programmable Gate Array Selection Notes

Select this component when a moderate logic density of 250,000 gates is sufficient for the target design. The Spartan-3E series offers a balance of performance and cost for established designs. Consider the 208-pin PQFP package constraints regarding board space and thermal dissipation requirements during the initial schematic capture phase.

Field Programmable Gate Array Part Context

This part is a member of the Xilinx Spartan-3E FPGA family, designed for high-volume, cost-sensitive applications. It succeeded earlier Spartan-3 devices with enhanced power efficiency and additional embedded block RAM. The Spartan-3E architecture remains widely used in legacy industrial and consumer products due to its mature toolchain support and reliability.

Field Programmable Gate Array FAQ

What is the difference between the -4 and -5 speed grades?

The -4 speed grade indicates a slower maximum operating frequency compared to the -5 speed grade. Both variants share identical logic resources and packaging but differ in timing characteristics.

Does the 'C' suffix affect the electrical functionality?

No, the 'C' suffix denotes the commercial temperature range (0°C to +85°C). It does not alter the logical function or pinout of the device compared to industrial variants.
