Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete LFECP6E-3FN484I is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 484-BBGA package with identical 23x23mm footprint dimensions to ensure PCB-level compatibility without redesign.

Electrical Specifications: Supply voltage range (1.14V ~ 1.26V) and operating temperature range (-40°C ~ 100°C TJ) must be maintained or exceeded to ensure functional equivalence in the target application.

I/O Pin Count: The substitute part must provide equal or greater I/O capacity (minimum 224 pins) to accommodate existing signal routing and interface requirements.

Logic Resources: The substitute must provide equal or greater logic element count (minimum 6100 cells) and RAM capacity (minimum 94208 bits) to support the original design's computational and storage requirements.

Manufacturer Continuity: Parts from Lattice Semiconductor Corporation within the ECP or ECP2 series maintain design tool compatibility and firmware consistency.

Regulatory Compliance: REACH and ECCN classifications must remain consistent to ensure compliance with export and environmental regulations.

Resource Superiority: The LFE2-12E-5FN484I provides doubled logic element capacity (12000 vs. 6100) and more than doubled RAM capacity (226304 vs. 94208 bits), offering enhanced design margin and future scalability.

I/O Expansion: The substitute provides 297 I/O pins compared to 224, supporting additional interface expansion without package constraints.

Active Product Status: The LFE2-12E-5FN484I is an active product with ongoing manufacturer support, ensuring long-term availability and supply chain stability.

Regulatory Alignment: Both parts maintain identical REACH, ECCN, and HTSUS classifications, preserving compliance posture across export and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484I replace the LFECP6E-3FN484I without PCB redesign?

A: Yes. Both devices use the 484-BBGA package with identical 23x23mm footprints and pin assignments for the common 224 I/O signals. The additional 73 I/O pins on the substitute are available for expansion but do not require PCB modification for basic replacement.

Q: Are the supply voltage requirements identical?

A: Yes. Both parts operate within the 1.14V ~ 1.26V supply range and share identical operating temperature specifications (-40°C ~ 100°C TJ), requiring no power delivery system modifications.

Q: What are the key differences between the ECP and ECP2 series?

A: The LFE2-12E-5FN484I (ECP2 series) provides enhanced logic density and RAM capacity compared to the ECP series. The substitute offers 12000 logic elements versus 6100, and 226304 RAM bits versus 94208, while maintaining identical electrical and package specifications.

Q: Is the LFE2-12E-5FN484I available in the same packaging format?

A: Yes. The substitute is supplied in 484-FPBGA (23x23) packaging, identical to the original part. Moisture sensitivity level (MSL 3, 168 hours) and handling requirements are also equivalent.

Q: Does the substitute support the same design tools and firmware?

A: Both parts are Lattice Semiconductor FPGA devices within compatible product families. Design tool compatibility and firmware support are maintained within the ECP and ECP2 series ecosystem.

Q: What is the inventory status of the substitute part?

A: The LFE2-12E-5FN484I is an active product with 1014 units in stock as new original inventory, ensuring immediate availability compared to the obsolete LFECP6E-3FN484I.
