Field Programmable Gate Array Procurement Notes

Verify the specific suffix '7' corresponds to the required speed grade and that the 'I' designation matches the intended industrial temperature range requirements. Confirm the FPBGA-1156 package dimensions align with the target PCB footprint constraints. Ensure compatibility with the design toolchain version supporting the ECP3 family architecture before finalizing procurement orders.

Field Programmable Gate Array Selection Notes

Select this model when the design requires approximately 92K LUTs and significant embedded memory capacity within a single FPGA die. Consider the 1156-pin package availability if board space permits larger footprints compared to smaller variants like the FN484 or FN672. Evaluate power consumption profiles against the system's thermal management capabilities, noting the 1.2V core voltage requirement.

Field Programmable Gate Array Part Context

This component belongs to the Lattice ECP3 series, which targets cost-sensitive applications needing moderate density and low power consumption. It serves as a bridge between lower-density ICE40 devices and higher-end CrossLink or MachXO families. The ECP3 architecture emphasizes efficiency, making it suitable for edge computing tasks where power and area are critical constraints.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to varying logic densities. The LFE3-95EA-8FN1156I offers a different speed grade but maintains identical pinout and functionality. Designers should verify timing closure requirements when substituting speed grades, as electrical characteristics may differ slightly despite functional equivalence.
