Key Parameters

Substitute Part Grouping Explanation

The ATF750C-10SU qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (Microchip Technology) and base product number (ATF750)
• Matching macrocell count (10) and I/O pin count (10)
• Identical maximum propagation delay specification (10 ns)
• Identical package type (24-SOIC with 0.295" width, 7.50mm)
• Same programmable type classification (EE PLD)
• Compatible mounting type (Surface Mount)

The ATF750C-10SU maintains electrical and mechanical compatibility with the ATF750C-10SC while offering extended operating temperature range and improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The ATF750C-10SU is the direct equivalent for the obsolete ATF750C-10SC. Selection of the ATF750C-10SU provides the following advantages:

• Active product status ensures continued availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements
• Extended operating temperature range (-40°C to 85°C) accommodates broader application environments compared to the original specification (0°C to 70°C)
• Wider voltage supply tolerance (4.5V to 5.5V) provides improved noise margin relative to the original specification (4.75V to 5.25V)
• Identical electrical performance characteristics (10 ns propagation delay, 10 macrocells, 10 I/O pins)
• Identical package footprint and mounting configuration ensure direct PCB compatibility

Frequently Asked Questions (FAQ)

Q: Can the ATF750C-10SU be used as a direct replacement for the ATF750C-10SC?

A: Yes. Both devices share identical macrocell count, I/O pin count, propagation delay, and package configuration. The ATF750C-10SU is electrically and mechanically compatible with the ATF750C-10SC.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), operating temperature range (-40°C to 85°C for the substitute versus 0°C to 70°C for the original), voltage supply tolerance (4.5V to 5.5V versus 4.75V to 5.25V), and compliance certifications (ROHS3 compliant versus non-compliant).

Q: Will the ATF750C-10SU fit the same PCB footprint?

A: Yes. Both parts use the 24-SOIC package with identical dimensions (0.295" width, 7.50mm). No PCB layout modifications are required.

Q: Is the ATF750C-10SU suitable for applications requiring extended temperature operation?

A: The ATF750C-10SU operates from -40°C to 85°C, which exceeds the original part's 0°C to 70°C specification. Applications requiring operation outside the original temperature range benefit from this extended capability.

Q: Are there any programming or configuration differences?

A: Both devices are EE PLD (Electrically Erasable Programmable Logic Device) types with identical macrocell and I/O architecture. Programming methodology and configuration procedures remain consistent between the two parts.
