Key Parameters

Substitute Part Grouping Explanation

Substitution of the EP1K30TC144-2 is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 144-LQFP (20x20mm) surface mount package to ensure PCB footprint compatibility without redesign.

I/O Pin Count: The substitute must provide a minimum of 102 I/O pins to maintain signal routing equivalence. The A3P125-TQG144 provides 100 I/O pins, representing a reduction of 2 pins from the original specification.

Logic Capacity: The substitute must provide sufficient logic elements and gate count to accommodate the original design. The A3P125-TQG144 offers 125000 gates, exceeding the EP1K30TC144-2's 119000 gates.

RAM Capacity: The substitute must provide adequate embedded RAM. The A3P125-TQG144 provides 36864 RAM bits, exceeding the original 24576 bits.

Voltage Supply: The substitute operates at 1.425V ~ 1.575V, which differs from the original 2.375V ~ 2.625V supply range, requiring power supply circuit modifications.

Operating Temperature Range: The substitute supports 0°C ~ 85°C (TJ), extending the upper temperature limit by 15°C compared to the original 0°C ~ 70°C (TA) specification.

Parameter Comparison

Engineering Selection Recommendations

The A3P125-TQG144 is the designated substitute for the obsolete EP1K30TC144-2. Selection of this substitute is justified by the following factors:

Product Status: The EP1K30TC144-2 is obsolete with no future availability. The A3P125-TQG144 maintains active product status with current manufacturing support and supply chain availability.

Compliance Status: The A3P125-TQG144 is ROHS3 compliant, meeting current environmental and regulatory requirements. The original EP1K30TC144-2 is RoHS non-compliant, making the substitute preferable for new designs subject to RoHS directives.

Regulatory Alignment: Both parts share identical ECCN (3A991D) and HTSUS (8542.39.0001) classifications, maintaining export and tariff consistency.

Package Equivalence: Both devices use the 144-LQFP (20x20mm) surface mount package, enabling direct PCB footprint compatibility without layout redesign.

Functional Capacity: The A3P125-TQG144 provides superior gate count (125000 vs. 119000) and RAM capacity (36864 vs. 24576 bits), ensuring adequate headroom for design migration.

Design Considerations: Implementation of the A3P125-TQG144 requires modification of power supply circuits due to the reduced voltage supply range (1.425V ~ 1.575V vs. 2.375V ~ 2.625V). The 2-pin I/O reduction (100 vs. 102) must be evaluated against specific design requirements. The extended operating temperature range (0°C ~ 85°C) provides improved thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the A3P125-TQG144 be used as a direct drop-in replacement for the EP1K30TC144-2?

A: The A3P125-TQG144 shares the same 144-LQFP package footprint, enabling PCB-level compatibility without layout changes. However, power supply circuit modifications are required due to the different voltage supply range. The 2-pin I/O reduction must be verified against your specific design pinout requirements.

Q: What is the impact of the 2-pin I/O reduction from 102 to 100 pins?

A: The A3P125-TQG144 provides 100 I/O pins compared to the original 102 pins. Design feasibility depends on whether your application utilizes all 102 pins. If fewer than 100 pins are required, substitution is straightforward. If all 102 pins are actively used, design modification or alternative parts must be evaluated.

Q: Are there voltage supply compatibility issues?

A: Yes. The EP1K30TC144-2 requires 2.375V ~ 2.625V supply, while the A3P125-TQG144 requires 1.425V ~ 1.575V. Power supply circuits must be redesigned to accommodate the lower voltage requirement. This is a mandatory design change for successful substitution.

Q: Does the A3P125-TQG144 provide sufficient logic capacity?

A: Yes. The A3P125-TQG144 provides 125000 gates and 36864 RAM bits, both exceeding the original EP1K30TC144-2 specifications (119000 gates and 24576 RAM bits). Logic capacity is not a limiting factor for substitution.

Q: What are the compliance differences between these parts?

A: The EP1K30TC144-2 is RoHS non-compliant and obsolete. The A3P125-TQG144 is ROHS3 compliant and maintains active product status. For new designs subject to RoHS requirements, the A3P125-TQG144 is the appropriate choice.

Q: Are there temperature range considerations?

A: The A3P125-TQG144 supports 0°C ~ 85°C (TJ), extending the upper operating limit by 15°C compared to the EP1K30TC144-2 (0°C ~ 70°C TA). This provides improved thermal margin for applications operating in elevated temperature environments.

Q: What is the moisture sensitivity level for both parts?

A: Both the EP1K30TC144-2 and A3P125-TQG144 have a Moisture Sensitivity Level (MSL) of 3 with a 168-hour floor life. Identical handling and storage requirements apply to both devices.
