Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix 'X' against official manufacturer documentation to confirm if it denotes a valid commercial variant or a specific qualification level. Confirm RoHS compliance status as standard FLEX 10K devices may not be compliant. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCN) from Altera/Intel, as this family is legacy technology.

Field Programmable Gate Array Selection Notes

Select the EPF10K50SFC256-2X when designs require 2.5 V core voltage and approximately 2,880 LEs. Ensure the application supports SRAM-based FPGA configuration via external serial devices or JTAG. Verify that the 256-pin FineLine BGA package fits the board space constraints and that the 191 available I/O pins meet interface requirements.

Field Programmable Gate Array Part Context

This component is part of the FLEX 10KE enhanced family, which offers higher density and performance compared to the original FLEX 10K series. It represents an embedded PLD architecture combining general-purpose logic arrays with specialized embedded array blocks for memory and complex logic functions.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Legacy replacements typically involve migration to newer Intel/Altera FPGA families such as Cyclone or Arria series, requiring architectural redesign.
