Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFECP10E-4FN256C is determined by the following critical parameters:

Electrical Compatibility: Supply voltage range (1.14V ~ 1.26V) must be maintained. The substitute part must operate within this specification to ensure direct compatibility with existing power delivery systems.

Package Compatibility: The 256-BGA package format (256-FPBGA 17x17) is mandatory. Pin count and physical dimensions must remain identical to ensure PCB layout compatibility without redesign.

I/O Pin Count: The substitute must provide a minimum of 193 I/O pins to accommodate existing signal routing. The LFECP10E-4FN256C provides 195 I/O pins; substitutes with 193 I/O pins remain functionally compatible for most applications.

Logic Element Capacity: The substitute must provide sufficient logic elements to accommodate the design. The LFECP10E-4FN256C contains 10,200 logic elements; substitutes with 12,000 logic elements provide headroom for design migration.

Operating Temperature Range: The 0°C ~ 85°C operating range must be maintained for thermal compatibility.

Manufacturer: Lattice Semiconductor Corporation maintains consistent design methodologies across the ECP and ECP2 series, ensuring architectural compatibility.

Engineering Selection Recommendations

The LFE2-12E-5FN256C is the qualified substitute for the LFECP10E-4FN256C based on the following engineering criteria:

Product Status: The LFECP10E-4FN256C is obsolete, while the LFE2-12E-5FN256C maintains active product status. This ensures long-term availability and manufacturing support for new designs and production continuity.

Compliance & Certifications: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory compliance without modification to export or supply chain documentation.

Electrical Specifications: Both devices operate within the identical 1.14V ~ 1.26V supply voltage range and 0°C ~ 85°C operating temperature window, eliminating the need for power delivery system redesign.

Package Compatibility: Both parts utilize the 256-FPBGA (17x17) package format, enabling direct PCB layout compatibility without board redesign.

Logic Capacity: The LFE2-12E-5FN256C provides 12,000 logic elements compared to the LFECP10E-4FN256C's 10,200 elements, offering additional design headroom during migration.

I/O Pin Count: The LFE2-12E-5FN256C provides 193 I/O pins versus 195 on the original part. This two-pin reduction is compatible with most applications; designs utilizing all 195 pins require signal routing verification.
