Substitute Part Grouping Explanation

Substitution of the EP20K600EFC672-1X is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 672-BBGA (27x27) package to ensure PCB footprint compatibility and pin assignment alignment.

I/O Pin Count: The substitute must provide a minimum of 500 I/O pins to accommodate designs originally specified for 508 I/O. The LFE2-50E-5FN672C provides 500 I/O pins, meeting this requirement.

Logic Density: The substitute must deliver sufficient logic elements and RAM capacity. The LFE2-50E-5FN672C provides 48,000 logic elements and 396,288 RAM bits, exceeding the original part's specifications.

Operating Temperature Range: Both parts operate across 0°C ~ 85°C (TJ), ensuring thermal compatibility.

Mounting Type: Both parts use surface mount technology, maintaining assembly process compatibility.

Supply Voltage: The substitute operates at 1.14V ~ 1.26V, which differs from the original 1.71V ~ 1.89V. This represents a distinct electrical characteristic that must be evaluated during design migration.

Parameter Comparison

Engineering Selection Recommendations

The LFE2-50E-5FN672C from Lattice Semiconductor Corporation is the qualified substitute for the obsolete EP20K600EFC672-1X. Selection of this substitute is supported by the following factors:

Product Status: The LFE2-50E-5FN672C maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete EP20K600EFC672-1X.

Regulatory Compliance: The LFE2-50E-5FN672C is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance advantage supports modern manufacturing and environmental standards.

Package Compatibility: Both parts use identical 672-BBGA packaging, eliminating PCB redesign requirements.

Thermal Compatibility: Matching operating temperature ranges (0°C ~ 85°C) ensure thermal performance equivalence.

Logic and Memory Capacity: The substitute provides increased logic elements (48,000 vs. 24,320) and RAM bits (396,288 vs. 311,296), offering design headroom for future enhancements.

I/O Pin Consideration: The substitute provides 500 I/O pins versus the original 508 I/O pins. Designs must confirm that the 8-pin reduction does not impact functional requirements.

Supply Voltage Difference: The substitute operates at 1.14V ~ 1.26V versus the original 1.71V ~ 1.89V. Power supply architecture and voltage regulation circuits must be re-evaluated during migration.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-50E-5FN672C directly replace the EP20K600EFC672-1X without PCB modifications?

A: The 672-BBGA package footprint is identical, eliminating PCB layout changes. However, the supply voltage range differs significantly (1.14V ~ 1.26V vs. 1.71V ~ 1.89V), requiring power supply circuit redesign and validation.

Q: What is the impact of the 8-pin I/O reduction (508 to 500)?

A: Designs must confirm that all 508 I/O pins were actively used in the original implementation. If fewer than 500 I/O pins are required, the substitute is fully compatible. If all 508 pins are essential, alternative solutions must be evaluated.

Q: Does the LFE2-50E-5FN672C provide sufficient logic capacity?

A: Yes. The substitute provides 48,000 logic elements and 396,288 RAM bits, both exceeding the original part's 24,320 logic elements and 311,296 RAM bits. This provides additional design capacity.

Q: Are there differences in moisture sensitivity handling?

A: Both parts share identical Moisture Sensitivity Level 3 (168 Hours) ratings, requiring equivalent storage and handling procedures.

Q: What is the significance of the RoHS compliance difference?

A: The LFE2-50E-5FN672C is ROHS3 compliant, meeting modern environmental and manufacturing standards. The original EP20K600EFC672-1X is RoHS non-compliant, which may restrict use in certain markets or applications with regulatory requirements.

Q: Are there any design tool or software compatibility considerations?

A: Design migration from APEX-20KE® to ECP2 architecture requires evaluation of HDL compatibility, synthesis tool support, and timing closure. These factors are outside the scope of electrical and mechanical parameter equivalence.
