Engineering Selection Recommendations

The ATF1502AS-7JX44 serves as a direct functional substitute for the obsolete EPM7032LC44-7. Selection of this alternative is supported by:

Electrical Equivalence: Identical propagation delay (7.5 ns), supply voltage range (4.75V–5.25V), and macrocell count (32) ensure functional compatibility in existing circuit designs.
Package Compatibility: Both devices utilize 44-pin PLCC packaging with J-Lead configuration and equivalent footprint dimensions, enabling direct PCB-level substitution.
Programmability Advantage: The ATF1502AS-7JX44 employs In System Programmable (ISP) technology with minimum 10K program/erase cycles, providing superior field reprogrammability compared to the EE PLD architecture of the original part.
Regulatory Compliance: The ATF1502AS-7JX44 achieves ROHS3 compliance, whereas the EPM7032LC44-7 is RoHS non-compliant, making the substitute preferable for new designs subject to environmental regulations.
Product Status: The ATF1502AS-7JX44 maintains active product status with verified programmability and current inventory availability (2252 units), ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the ATF1502AS-7JX44 directly replace the EPM7032LC44-7 in existing designs?

A: Yes. Both devices share identical 44-pin PLCC packaging, equivalent propagation delay (7.5 ns), matching supply voltage specifications (4.75V–5.25V), and equivalent macrocell count (32). Direct PCB substitution is feasible without layout modifications.

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

A: The EPM7032LC44-7 provides 36 I/O pins, while the ATF1502AS-7JX44 provides 32 I/O pins. The substitute meets the minimum I/O requirement for functional equivalence. Designs utilizing more than 32 I/O pins require circuit redesign.

Q: How does the programmability differ between these parts?

A: The EPM7032LC44-7 uses EE PLD (Electrically Erasable Programmable Logic Device) technology. The ATF1502AS-7JX44 uses In System Programmable (ISP) technology with minimum 10K program/erase cycles, enabling field reprogramming without device removal.

Q: Are there compliance differences between these devices?

A: Yes. The EPM7032LC44-7 is RoHS non-compliant, while the ATF1502AS-7JX44 is ROHS3 compliant. Both devices share identical ECCN (3A991D) and HTSUS (8542.39.0001) classifications and are REACH unaffected.

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

A: Both the EPM7032LC44-7 and ATF1502AS-7JX44 are classified as MSL 3 (168 Hours), requiring equivalent moisture control and handling procedures during storage and assembly.

Q: Is the ATF1502AS-7JX44 currently available?

A: Yes. The ATF1502AS-7JX44 maintains active product status with 2252 units in current inventory, ensuring availability for immediate procurement and deployment.
