Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFE2M20SE-7F256C is determined by strict equivalence across the following critical parameters:

• Series and Architecture: Both parts belong to the ECP2M FPGA family, ensuring architectural compatibility
• Logic Capacity: Identical logic element count (19,000) and LAB/CLB configuration (2,375)
• Memory Configuration: Matching embedded RAM capacity (1,246,208 bits)
• I/O Count: Identical 140 I/O pin configuration
• Electrical Specifications: Matching supply voltage range (1.14V ~ 1.26V) and operating temperature range (0°C ~ 85°C)
• Package Specification: Both use 256-BGA package with 256-FPBGA (17x17) footprint
• Mounting Technology: Surface mount compatibility maintained

The primary distinction between the main part and its substitute relates to product status and packaging format, not functional or electrical parameters.

Engineering Selection Recommendations

The LFE2M20SE-7FN256C serves as a direct functional equivalent to the LFE2M20SE-7F256C. Selection between these parts should be based on the following criteria:

Product Status: The LFE2M20SE-7F256C is classified as obsolete, while the LFE2M20SE-7FN256C maintains active product status. For new designs or long-term production requirements, the active part is the appropriate selection.

Regulatory Compliance: The LFE2M20SE-7FN256C is ROHS3 compliant, whereas the LFE2M20SE-7F256C is RoHS non-compliant. Applications subject to RoHS regulations require the compliant variant.

Packaging and Handling: Both parts maintain identical MSL ratings (3, 168 Hours). The packaging format difference (tube versus tray) affects logistics and assembly processes but does not impact electrical or functional performance.

Electrical and Functional Equivalence: All critical electrical parameters, logic capacity, memory configuration, I/O count, and thermal specifications are identical, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LFE2M20SE-7FN256C be used as a direct replacement for the LFE2M20SE-7F256C?

A: Yes. Both parts are functionally and electrically equivalent. They share identical logic element counts, I/O configurations, memory capacity, supply voltage ranges, and operating temperature specifications. The primary differences are product status and RoHS compliance.

Q: What is the significance of the product status difference?

A: The LFE2M20SE-7F256C is obsolete, indicating Lattice Semiconductor has discontinued production and support. The LFE2M20SE-7FN256C is active, meaning it remains in production with ongoing manufacturer support. For new designs or sustained production, the active part is recommended.

Q: Are there any package or footprint differences?

A: No. Both parts use the 256-BGA package with identical 256-FPBGA (17x17) footprint specifications. PCB layout and assembly processes remain unchanged.

Q: Does RoHS compliance affect functionality?

A: RoHS compliance does not alter electrical performance or functionality. It reflects manufacturing process compliance with environmental regulations. Applications subject to RoHS requirements must use the ROHS3 compliant variant (LFE2M20SE-7FN256C).

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have MSL rating 3 with a 168-hour floor life specification. Handling, storage, and reflow procedures are identical.

Q: What parameters determine substitution eligibility?

A: Substitution is determined by matching series (ECP2M), logic element count (19,000), I/O configuration (140), embedded RAM capacity (1,246,208 bits), supply voltage range (1.14V ~ 1.26V), operating temperature range (0°C ~ 85°C), and package specification (256-BGA).
