Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPF8636ALC84-3 is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 84-LCC (J-Lead) surface mount package with identical physical dimensions (29.31x29.31mm)
• I/O Pin Count: Minimum 68 I/O pins required; higher pin counts are acceptable if design routing permits
• Logic Capacity: Minimum 504 logic elements and 6000 gates to maintain functional equivalence
• Supply Voltage Range: Must support the 4.75V to 5.25V operating range
• Operating Temperature Range: Must support 0°C to 70°C minimum
• Mounting Type: Surface mount configuration required for PCB compatibility

The A40MX04-PLG84 meets these substitution criteria while offering active product status and enhanced voltage flexibility.

Engineering Selection Recommendations

The A40MX04-PLG84 is a direct functional substitute for the obsolete EPF8636ALC84-3. Selection should be based on the following factors:

• Product Lifecycle: The A40MX04-PLG84 maintains active product status, ensuring long-term availability and manufacturing support compared to the obsolete EPF8636ALC84-3
• Regulatory Compliance: The A40MX04-PLG84 is ROHS3 compliant, meeting current environmental and regulatory requirements
• Voltage Flexibility: The A40MX04-PLG84 supports dual voltage ranges (3V ~ 3.6V and 4.75V ~ 5.25V), providing design flexibility beyond the single 4.75V ~ 5.25V range of the original part
• Pin Count: The A40MX04-PLG84 provides 69 I/O pins versus 68 on the original part, offering one additional I/O option without package size changes
• Package Equivalence: Identical 84-LCC (J-Lead) package and physical dimensions ensure direct PCB compatibility

Frequently Asked Questions (FAQ)

Q: Can the A40MX04-PLG84 be used as a direct replacement for the EPF8636ALC84-3 on existing PCBs?

A: Yes. Both parts use identical 84-LCC (J-Lead) packages with matching physical dimensions (29.31x29.31mm) and surface mount configuration. PCB layout and footprints require no modification.

Q: What is the difference in I/O pin count between these parts?

A: The EPF8636ALC84-3 provides 68 I/O pins, while the A40MX04-PLG84 provides 69 I/O pins. The additional pin does not affect package compatibility or footprint requirements.

Q: Are the supply voltage ranges compatible?

A: The EPF8636ALC84-3 operates at 4.75V ~ 5.25V. The A40MX04-PLG84 supports both 3V ~ 3.6V and 4.75V ~ 5.25V ranges. Designs using the original 4.75V ~ 5.25V supply voltage are fully compatible with the substitute part.

Q: What is the logic capacity equivalence?

A: Both parts provide 6000 gates and equivalent logic element density, ensuring functional equivalence for designs originally targeting the EPF8636ALC84-3.

Q: Does the A40MX04-PLG84 meet current environmental standards?

A: Yes. The A40MX04-PLG84 is ROHS3 compliant, meeting current environmental and regulatory requirements. The original EPF8636ALC84-3 REACH status is unaffected.

Q: What is the operating temperature range for both parts?

A: Both the EPF8636ALC84-3 and A40MX04-PLG84 support 0°C to 70°C operating temperature range, ensuring thermal compatibility in equivalent applications.
