Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF22V10C-15SC is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the 22V10 series to ensure functional equivalence
• Macrocell Count: Identical at 10 macrocells for logic capacity matching
• Input Voltage: Both operate at 5V, ensuring power supply compatibility
• Package Type: Both use 24-SOIC surface mount packaging for PCB layout compatibility
• Programmable Type: Both are EE PLD (Electrically Erasable Programmable Logic Device) for reprogrammability
• Speed Parameter: The substitute part operates at 10 ns, which is faster than the original 15 ns specification, making it a direct functional replacement with improved performance characteristics

The ATF22V10C-10SU is identified as the manufacturer-recommended substitute, meeting all critical compatibility criteria while offering enhanced speed performance.

Parameter Comparison

Engineering Selection Recommendations

The ATF22V10C-10SU is the appropriate substitute for the obsolete ATF22V10C-15SC based on the following factors:

Product Status: The substitute part is classified as Active, ensuring continued availability and manufacturer support, whereas the original part is Obsolete and subject to supply discontinuation.

Compliance: The ATF22V10C-10SU is ROHS3 compliant, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant, which may present procurement and regulatory challenges in modern manufacturing environments.

Performance: The substitute operates at 10 ns propagation delay, which is superior to the original 15 ns specification. This faster speed is backward-compatible with designs requiring the original 15 ns timing, as the substitute will meet or exceed all timing requirements.

Functional Equivalence: Both parts share identical macrocell count, input voltage, package type, and programmable architecture, ensuring direct functional replacement without design modification.

Packaging: Both parts use identical 24-SOIC surface mount packaging, allowing direct PCB footprint compatibility without layout changes.

Frequently Asked Questions (FAQ)

Q: Can the ATF22V10C-10SU directly replace the ATF22V10C-15SC on existing PCBs?

A: Yes. Both parts use identical 24-SOIC surface mount packaging with the same pinout and footprint. No PCB layout modifications are required.

Q: Will the faster 10 ns speed of the substitute cause compatibility issues?

A: No. The 10 ns speed specification of the ATF22V10C-10SU is faster than the original 15 ns requirement, making it a direct functional replacement. Designs originally specified for 15 ns will operate correctly with the faster substitute part.

Q: Are the programming algorithms identical between these parts?

A: Both parts are EE PLD (Electrically Erasable Programmable Logic Device) devices within the 22V10 series. Programming compatibility is maintained across the series for equivalent macrocell configurations.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The original part has MSL 1 (Unlimited shelf life), while the substitute has MSL 2 (1 Year shelf life). This means the substitute part requires storage in controlled humidity conditions and has a one-year maximum shelf life from the date of manufacture. Proper handling and storage procedures must be followed.

Q: Why is the original part classified as Obsolete?

A: Microchip Technology has discontinued the ATF22V10C-15SC in favor of the faster ATF22V10C-10SU variant. The substitute part provides superior performance characteristics while maintaining full functional compatibility.

Q: Are there any voltage or power supply differences?

A: No. Both parts operate at 5V input voltage, requiring identical power supply specifications and circuit design considerations.
