Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LFEC10E-3FN484C is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 484-BBGA package with identical 23x23mm dimensions to ensure PCB footprint compatibility
• Supply Voltage Range: Substitute parts must operate within the 1.14V ~ 1.26V supply voltage specification
• I/O Pin Count: The substitute must provide equal or greater I/O capability (minimum 288 pins)
• Logic Element Capacity: The substitute must provide equal or greater logic element count (minimum 10,200 cells)
• RAM Capacity: The substitute must provide equal or greater total RAM bits (minimum 282,624 bits)
• Operating Temperature Range: The substitute must support the 0°C ~ 85°C operating temperature specification
• Mounting Type: Surface mount technology must be maintained

The LFE2-12E-5FN484C meets all substitution criteria as an active product offering enhanced specifications within the same package footprint.

• Compliance: Both parts maintain identical MSL rating (3, 168 Hours) and REACH compliance status
• Series Progression: The LFE2-12E-5FN484C represents the next generation in Lattice's FPGA product line, offering improved performance characteristics within the same physical constraints

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484C be used as a direct replacement for the LFEC10E-3FN484C?

A: Yes. Both devices use the 484-BBGA package with identical 23x23mm dimensions, matching supply voltage (1.14V ~ 1.26V), and identical operating temperature range (0°C ~ 85°C). The substitute can be placed on the same PCB footprint without modification.

Q: What are the key differences between these two parts?

A: The LFE2-12E-5FN484C provides 12,000 logic elements compared to 10,200 in the LFEC10E-3FN484C, and 297 I/O pins versus 288. The main part offers 282,624 RAM bits while the substitute provides 226,304 RAM bits. The substitute is an active product, whereas the main part is obsolete.

Q: Does the substitute have the same moisture sensitivity level?

A: Yes. Both parts have MSL rating 3 (168 Hours), requiring identical handling and storage protocols.

Q: Are there any voltage or temperature compatibility concerns?

A: No. Both parts operate within the identical supply voltage range (1.14V ~ 1.26V) and temperature range (0°C ~ 85°C TJ), ensuring compatibility with existing power delivery and thermal management designs.

Q: What is the significance of the substitute being an active product?

A: Active product status ensures ongoing manufacturer support, availability from distribution channels, and continued technical documentation updates. The obsolete status of the main part makes the active substitute essential for long-term system support and future procurement.

Q: Are there any design considerations for the increased I/O count?

A: The substitute provides 9 additional I/O pins (297 versus 288). Designs utilizing only the original 288 pins will function without modification. Additional pins remain available for future design enhancements.

Q: How do the logic element counts affect design migration?

A: The substitute provides 1,800 additional logic elements (12,000 versus 10,200). Existing designs will function without modification, with additional logic capacity available for design expansion or optimization.
