Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized distributors as this part number belongs to a legacy product line. Confirm that the 208-RQFP package matches the target PCB footprint dimensions. Ensure design tools support the FLEX 10K architecture for compilation and simulation. Check for any specific environmental compliance requirements relative to the manufacturing date.

Field Programmable Gate Array Selection Notes

Select this model when 2,304 logic elements and 16 Kbits of embedded memory are required within a 208-pin surface-mount package. Compare against EPF10K30 for lower density needs or EPF10K50 for higher capacity. Ensure the 5.0 V supply voltage requirement aligns with the system power rails. Consider the -4 speed grade if timing constraints require frequencies up to approximately 95 MHz for specific logic functions.

Field Programmable Gate Array Part Context

This component is part of the FLEX 10K series, recognized as the industry's first embedded programmable logic device family. It bridges the gap between standard gate arrays and field-programmable gate arrays by integrating dedicated megafunction areas with reconfigurable logic. The EPF10K40 variant specifically targets applications needing moderate density with significant embedded memory resources.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package may include other FLEX 10K devices such as EPF10K30RC208 or EPF10K50RC208, subject to logic resource availability. Verify electrical characteristics and speed grades match the original design requirements before substitution.
