Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific -3V speed grade and QC208 package variant against design requirements. Check for end-of-life status or obsolescence notices prior to procurement planning.

Selection Notes

Select this model for designs requiring 4,160 logic elements and 2.5 V operation. Ensure the 208-pin QFP package fits the board layout constraints. Verify that the 300 MHz performance meets timing requirements. Consider the -3V suffix for specific speed binning if higher performance than standard grades is needed.

Part Context

This part belongs to the APEX 20K series, representing early SOPC integration technology. It bridges CPLD and FPGA capabilities using a hybrid architecture. The EP20K100 variant offers mid-range density within the family, suitable for moderate complexity logic designs before transitioning to larger devices like the EP20K160E.

Replacement Considerations

No direct public substitutes are listed. Legacy replacements may include other APEX 20K variants or later Intel/Altera FPGA families such as Stratix or Cyclone, though architectural differences require full design re-verification.
