Substitute Part Grouping Explanation

Substitution of the EPM7064AEFC100-7 is determined by the following critical parameters:

• Macrocell Count: 64 macrocells (functional equivalence requirement)
• I/O Pin Count: Minimum 64 I/O pins (functional requirement; the original part provides 68)
• Programmable Type: In System Programmable capability (design requirement)
• Voltage Supply: 3V ~ 3.6V internal supply compatibility
• Package Type: Surface mount technology (design constraint)
• RoHS Compliance: RoHS3 or equivalent compliance status

The ATF1504ASV-15AU100 from Microchip Technology meets these substitution criteria. While the package format differs (100-TQFP versus 100-LBGA) and propagation delay is higher (15 ns versus 7.5 ns), the device maintains functional equivalence through matching macrocell count, in-system programmability, voltage supply range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ATF1504ASV-15AU100 is an active product with current manufacturing support and supply availability, addressing the obsolescence status of the EPM7064AEFC100-7. Both devices maintain identical voltage supply ranges (3V ~ 3.6V) and equivalent moisture sensitivity levels (MSL 3).

Key considerations for selection:

• Compliance: Both devices are RoHS compliant. The substitute carries ROHS3 compliance, meeting current regulatory requirements.
• Programmability: Both devices support in-system programmability, maintaining design methodology compatibility.
• Operating Temperature Range: The substitute provides an extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), offering broader environmental capability.
• Package Footprint: The substitute uses a 100-TQFP package (14x14 mm) compared to the original 100-LBGA package (11x11 mm), requiring PCB layout modification.
• I/O Pin Count: The substitute provides 64 I/O pins versus 68 on the original part. Design verification is required to confirm I/O requirements do not exceed 64 pins.
• Propagation Delay: The substitute has a maximum propagation delay of 15 ns compared to 7.5 ns on the original part. Timing-critical applications must validate that system performance requirements are met.

Frequently Asked Questions (FAQ)

Q: Can the ATF1504ASV-15AU100 directly replace the EPM7064AEFC100-7 without design changes?

A: Direct replacement requires PCB layout modification due to package format differences (100-TQFP versus 100-LBGA). Additionally, designs utilizing more than 64 I/O pins or requiring propagation delays faster than 15 ns cannot use this substitute without functional redesign.

Q: What is the primary reason for substitution?

A: The EPM7064AEFC100-7 is obsolete. The ATF1504ASV-15AU100 is an active product with current supply availability and manufacturing support.

Q: Are both devices compatible with the same programming methodology?

A: Both devices support in-system programmability. However, programming tools and firmware compatibility must be verified with the respective manufacturer documentation.

Q: Does the substitute meet the same compliance requirements?

A: Both devices are RoHS compliant with identical moisture sensitivity levels (MSL 3, 168 hours). The substitute carries ROHS3 compliance, meeting current regulatory standards.

Q: What are the critical differences in electrical performance?

A: The substitute has a maximum propagation delay of 15 ns compared to 7.5 ns on the original part. Both devices operate within the same voltage supply range (3V ~ 3.6V). The substitute provides an extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C).

Q: How many I/O pins does the substitute provide?

A: The ATF1504ASV-15AU100 provides 64 I/O pins, compared to 68 on the EPM7064AEFC100-7. Designs must confirm that I/O requirements do not exceed 64 pins.
