Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LFE2M20SE-7F484C is determined by strict equivalence across the following critical parameters:

• Logic Architecture: Identical ECP2M series designation and 19,000 logic element count
• Memory Configuration: Matching 1,246,208 total RAM bits
• I/O Count: Equivalent 304 I/O pins
• Electrical Specifications: Identical 1.14V ~ 1.26V supply voltage range and 0°C ~ 85°C operating temperature
• Package Specification: Same 484-BBGA package footprint (23x23mm)
• Mounting Technology: Surface mount compatibility

The substitute part LFE2M20SE-7FN484C meets all these criteria while differing only in packaging format (Tray vs. unspecified) and product lifecycle status.

Engineering Selection Recommendations

The LFE2M20SE-7FN484C serves as the direct functional equivalent to the obsolete LFE2M20SE-7F484C. Selection between these parts should be based on the following criteria:

For New Designs and Ongoing Production: The LFE2M20SE-7FN484C is the appropriate choice. This part maintains active product status with Lattice Semiconductor and carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component procurement.

For Legacy System Support: The LFE2M20SE-7F484C remains electrically and mechanically compatible with existing designs. However, procurement of this obsolete part may face supply constraints. The LFE2M20SE-7FN484C provides identical functional performance and can be substituted without design modification.

Compliance Considerations: Organizations subject to RoHS directives should prioritize the LFE2M20SE-7FN484C due to its ROHS3 compliance status. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the LFE2M20SE-7FN484C be used as a direct replacement for the LFE2M20SE-7F484C?
