Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF750LVC-15JC is determined by strict equivalence across the following critical parameters:

• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device)
• Number of Macrocells: 10
• Number of I/O: 10
• Delay Time tpd(1) Max: 15 ns
• Package / Case: 28-LCC (J-Lead)
• Mounting Type: Surface Mount
• Manufacturer: Microchip Technology
• Series: ATF750LVC

The substitute part ATF750LVC-15JU meets all these criteria. Differences in voltage supply range, operating temperature range, product status, and compliance certifications do not affect functional substitutability for applications designed around the ATF750LVC-15JC specifications.

Parameter Comparison

Engineering Selection Recommendations

The ATF750LVC-15JU is a direct functional substitute for the ATF750LVC-15JC. Both devices share identical core specifications: 10 macrocells, 10 I/O pins, 15 nanosecond maximum propagation delay, and 28-pin PLCC surface mount packaging.

The ATF750LVC-15JU offers extended advantages:

• Active product status ensures ongoing manufacturer support and availability
• Extended operating temperature range (-40°C to 85°C) accommodates broader environmental conditions
• Expanded voltage supply range (3V to 5.5V) provides additional design flexibility
• ROHS3 compliance meets current regulatory requirements
• Higher inventory availability supports production continuity

For applications currently using the obsolete ATF750LVC-15JC, the ATF750LVC-15JU provides equivalent electrical and mechanical performance with improved compliance and availability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the ATF750LVC-15JU directly replace the ATF750LVC-15JC in existing designs?

A: Yes. Both devices are electrically and mechanically equivalent across all functional parameters: macrocell count, I/O count, propagation delay, and package type. The ATF750LVC-15JU operates within the voltage and temperature specifications of the ATF750LVC-15JC, ensuring compatibility in existing circuit designs.

Q: What is the significance of the product status difference?

A: The ATF750LVC-15JC is classified as obsolete, indicating discontinued manufacturing and limited availability. The ATF750LVC-15JU maintains active status, ensuring continued production, technical support, and supply chain availability.

Q: Are there packaging differences between these parts?

A: No. Both devices use identical 28-pin PLCC (J-Lead) surface mount packaging with the same physical dimensions (11.51x11.51 mm). PCB layouts and assembly processes require no modification.

Q: How do the voltage supply ranges differ?

A: The ATF750LVC-15JC operates from 3V to 5.25V, while the ATF750LVC-15JU extends to 5.5V. Applications designed for the ATF750LVC-15JC operate within the ATF750LVC-15JU voltage range, making the substitute compatible.

Q: What is the impact of the extended operating temperature range?

A: The ATF750LVC-15JU supports -40°C to 85°C, compared to the ATF750LVC-15JC range of 0°C to 70°C. This extended range provides greater flexibility for applications requiring operation in wider temperature environments, though designs limited to 0°C to 70°C remain fully compatible.

Q: Does RoHS compliance affect substitution?

A: RoHS compliance is a manufacturing and supply chain consideration, not a functional parameter. The ROHS3 compliance of the ATF750LVC-15JU meets current regulatory requirements and does not affect electrical or mechanical compatibility with designs using the non-compliant ATF750LVC-15JC.
