Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPF10K50EFC484-1 is determined by the following critical parameters:

• Package compatibility: 484-BBGA (23x23) form factor
• I/O pin count: Minimum 220 I/O pins
• Logic capacity: Minimum 2880 logic elements
• RAM capacity: Minimum 40960 bits
• Surface mount technology
• Operating temperature range: 0°C ~ 70°C or broader
• Moisture sensitivity level: 3 (168 Hours)

The LFE3-17EA-7FN484C from Lattice Semiconductor Corporation meets these substitution criteria through equivalent package geometry, I/O count, and logic capacity specifications.

Parameter Comparison

Engineering Selection Recommendations

The LFE3-17EA-7FN484C qualifies as a substitute for the obsolete EPF10K50EFC484-1 based on the following factors:

• Active product status ensures ongoing availability and supply chain support
• Identical 484-BBGA package footprint (23x23) enables direct PCB compatibility
• I/O pin count of 222 exceeds the required 220 pins
• Logic element capacity of 17000 exceeds the required 2880 elements
• RAM capacity of 716800 bits exceeds the required 40960 bits
• Surface mount technology and MSL rating match original specifications
• Extended operating temperature range (0°C ~ 85°C) provides broader thermal coverage
• RoHS3 compliance and REACH unaffected status align with modern regulatory requirements

The primary design consideration is the supply voltage difference: the substitute operates at 1.14V ~ 1.26V versus the original 2.3V ~ 2.7V. Power supply architecture modifications are required for implementation.

Frequently Asked Questions (FAQ)

Q: Can the LFE3-17EA-7FN484C be used as a direct replacement without PCB modifications?

A: The 484-BBGA package footprint is identical, enabling direct PCB placement. However, power supply circuitry must be redesigned to accommodate the lower voltage requirement (1.14V ~ 1.26V versus 2.3V ~ 2.7V).

Q: Are there pin-to-pin compatibility concerns between these devices?

A: Both devices use the 484-BBGA package with identical physical dimensions (23x23). The substitute provides 222 I/O pins versus 220 on the original, offering additional I/O capacity. Pin assignment verification against specific application requirements is necessary.

Q: What is the impact of the increased logic capacity in the substitute part?

A: The LFE3-17EA-7FN484C provides 17000 logic elements compared to 2880 in the original device. This excess capacity does not create compatibility issues; designs utilizing the original capacity will function within the substitute's specifications.

Q: How do the operating temperature ranges compare?

A: The substitute supports 0°C ~ 85°C (TJ) versus the original 0°C ~ 70°C (TA). The extended upper temperature limit provides additional thermal margin for demanding applications.

Q: What compliance certifications apply to the substitute part?

A: The LFE3-17EA-7FN484C is RoHS3 compliant and REACH unaffected, meeting current regulatory standards. Both devices share identical MSL ratings of 3 (168 Hours).
