Field Programmable Gate Array Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Ensure compliance with RoHS status indicated as non-compliant in source data. Confirm humidity sensitivity handling procedures prior to assembly.

Field Programmable Gate Array Selection Notes

Select this part for designs requiring 5.0 V operation and moderate logic density. The 208-pin RQFP package suits surface-mount applications needing 147 I/Os. Compare against EPF10K10 for lower resource needs or EPF10K30 for higher capacity. Verify that the 5.0 V supply requirement aligns with system power rails, as 3.3 V variants exist in the same family.

Field Programmable Gate Array Part Context

The EPF10K20RI208-4 belongs to the FLEX 10K series, recognized as the industry's first embedded programmable logic device family. This architecture combines general-purpose logic arrays with embedded memory blocks to facilitate System-on-a-Programmable-Chip solutions. The 'R' suffix denotes the RQFP package type, while 'I208' indicates the 208-pin configuration and commercial temperature grade.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the EOL status. Consider EPF10K10RI208-4 for reduced resource requirements or EPF10K30RI208-4 for increased capacity, provided the pinout remains compatible. Cross-family migration to Cyclone or MAX devices requires schematic redesign.
