Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFEC10E-5FN256C is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 256-BGA (17x17) package to ensure PCB footprint compatibility and mounting feasibility.

Electrical Specifications: Supply voltage range (1.14V ~ 1.26V) and operating temperature range (0°C ~ 85°C) must be maintained to ensure functional equivalence in the target application.

I/O Pin Count: The substitute part must provide a minimum of 195 I/O pins to support existing circuit designs without requiring board redesign.

Logic Capacity: The substitute must provide sufficient logic elements and RAM bits to accommodate the original design's functional requirements.

Manufacturer Alignment: Lattice Semiconductor Corporation remains the source for compatible FPGA solutions within this architecture family.

The LFE2-12E-5FN256C qualifies as a substitute based on matching package type, electrical specifications, I/O count, and manufacturer origin, while offering enhanced logic capacity and active product status.

Engineering Selection Recommendations

The LFE2-12E-5FN256C is the designated substitute for the obsolete LFEC10E-5FN256C based on the following engineering criteria:

Product Status: The substitute part maintains active product status with Lattice Semiconductor Corporation, ensuring long-term availability and continued manufacturing support compared to the obsolete main part.

Regulatory Compliance: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining compliance requirements across design transitions.

Packaging and Thermal Characteristics: Identical 256-BGA (17x17) package type, mounting method, and moisture sensitivity level (MSL 3) ensure direct PCB compatibility without layout modifications.

Electrical Equivalence: Matching supply voltage range and operating temperature specifications preserve system-level electrical performance and thermal management strategies.

I/O and Logic Capacity: The substitute provides 193 I/O pins (2 pins fewer than the main part) and 12,000 logic elements (1,800 elements more than the main part), offering enhanced computational capacity with minimal I/O reduction suitable for most design migrations.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN256C directly replace the LFEC10E-5FN256C without PCB modifications?

A: Yes, both parts use the identical 256-BGA (17x17) package footprint. PCB layout remains unchanged. However, verify that your design does not require all 195 I/O pins, as the substitute provides 193 I/O pins.

Q: What is the difference in logic capacity between these parts?

A: The LFEC10E-5FN256C contains 10,200 logic elements and 282,624 RAM bits. The LFE2-12E-5FN256C contains 12,000 logic elements and 226,304 RAM bits. The substitute offers more logic capacity but less embedded RAM.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both parts operate at 1.14V ~ 1.26V supply voltage and 0°C ~ 85°C junction temperature, ensuring equivalent electrical performance in the target application.

Q: Why is the main part listed as obsolete?

A: The LFEC10E-5FN256C is an older EC series device. Lattice Semiconductor has transitioned to newer architectures such as the ECP2 series, represented by the LFE2-12E-5FN256C, which offers improved performance and continued manufacturing support.

Q: Are there any compliance or certification differences?

A: No. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and moisture sensitivity level (MSL 3, 168 Hours), maintaining regulatory equivalence.

Q: What should I verify before implementing this substitution?

A: Confirm that your design accommodates the 2-pin I/O reduction (195 to 193 pins) and verify that the increased logic element capacity (12,000 vs. 10,200) does not introduce timing or power consumption concerns in your specific application.
