Key Parameters

Substitute Part Grouping Explanation

Substitution of the EP1K100FC484-1 is based on the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 484-FBGA (23x23) footprint to ensure PCB layout compatibility without redesign.

I/O Pin Count: The substitute must provide a minimum of 333 I/O pins to maintain signal routing equivalence. The LCMXO2-7000HC-4FG484C provides 334 I/O pins, meeting this requirement.

Logic Capacity: The substitute must provide sufficient logic elements and RAM to accommodate designs originally targeting the EP1K100FC484-1. The LCMXO2-7000HC-4FG484C offers 6864 logic elements and 245760 RAM bits, exceeding the original specifications.

Voltage Supply Range: The substitute must operate within or encompass the original supply voltage range. The LCMXO2-7000HC-4FG484C supports 2.375V ~ 3.465V, which includes the original 2.375V ~ 2.625V range.

Mounting Type: Both devices use Surface Mount technology, ensuring assembly process compatibility.

Moisture Sensitivity: Both devices share MSL 3 (168 Hours) classification, maintaining equivalent handling and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

The LCMXO2-7000HC-4FG484C is a direct substitute for the EP1K100FC484-1 based on package footprint compatibility, I/O pin count equivalence, and enhanced logic capacity. The substitute device is in active production status, ensuring long-term availability and supply chain stability compared to the obsolete EP1K100FC484-1.

The LCMXO2-7000HC-4FG484C provides superior specifications in logic elements (6864 vs. 4992), RAM capacity (245760 vs. 49152 bits), and operating temperature range (0°C ~ 85°C vs. 0°C ~ 70°C). The extended voltage supply range (2.375V ~ 3.465V) encompasses the original specification, supporting existing power delivery designs.

The substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both devices share identical ECCN and HTSUS classifications, maintaining regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can the LCMXO2-7000HC-4FG484C be used as a direct replacement without PCB redesign?

A: Yes. Both devices use the 484-FBGA (23x23) package footprint, enabling direct PCB layout compatibility. No board redesign is required for package substitution.

Q: Are the I/O pin counts compatible?

A: Yes. The LCMXO2-7000HC-4FG484C provides 334 I/O pins compared to the EP1K100FC484-1's 333 I/O pins. The single additional I/O pin does not prevent substitution and provides design flexibility.

Q: What are the voltage supply differences?

A: The EP1K100FC484-1 operates at 2.375V ~ 2.625V, while the LCMXO2-7000HC-4FG484C operates at 2.375V ~ 3.465V. The substitute's range encompasses the original specification, ensuring compatibility with existing power supplies designed for the original part.

Q: Does the substitute provide sufficient logic capacity?

A: Yes. The LCMXO2-7000HC-4FG484C provides 6864 logic elements and 245760 RAM bits, exceeding the EP1K100FC484-1's 4992 logic elements and 49152 RAM bits. Designs targeting the original part will operate within the substitute's capacity.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both devices are classified as MSL 3 (168 Hours), requiring identical handling, storage, and reflow procedures.

Q: What is the impact of the extended operating temperature range?

A: The LCMXO2-7000HC-4FG484C supports 0°C ~ 85°C (TJ) compared to the EP1K100FC484-1's 0°C ~ 70°C (TA). The extended range provides additional thermal margin for applications operating at elevated temperatures.

Q: Are there compliance differences between the two parts?

A: The LCMXO2-7000HC-4FG484C is ROHS3 compliant, while the EP1K100FC484-1 is RoHS non-compliant. Both devices share identical ECCN (3A991D) and HTSUS (8542.39.0001) classifications for regulatory and trade purposes.
