Field Programmable Gate Array Procurement Notes

This component is listed as End-of-Life. Verification of authenticity is critical when sourcing from secondary markets. Confirm RoHS compliance status and moisture sensitivity handling requirements prior to installation. Availability is limited to existing stock or surplus channels.

Field Programmable Gate Array Selection Notes

Select this part for designs requiring 5.0-V logic levels and embedded memory within a 240-pin QFP package. Ensure the design fits within the 2,880 LE and 20 kbit RAM constraints. Verify that the 0°C to +70°C operating temperature range meets environmental specifications. Consider pin compatibility if migrating within the FLEX 10K family.

Field Programmable Gate Array Part Context

The EPF10K50RI240-4N is part of the FLEX 10K series, recognized as the industry's first embedded PLD family. It combines general-purpose logic arrays with dedicated embedded array blocks for memory and specialized functions. This architecture allows for high-density system integration on a single chip.

Field Programmable Gate Array Replacement Considerations

Direct replacements are unavailable due to the End-of-Life status. Designers may consider migration to newer Intel/Altera FPGA families such as Cyclone or Arria, though pinouts and architectures differ significantly. Legacy support requires careful evaluation of software tool compatibility.
