Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF750CL-15JC is determined by the following critical parameters:

• Identical macrocell count (10 macrocells)
• Identical I/O pin count (10 pins)
• Matching propagation delay specification (15 ns maximum)
• Compatible package type (28-LCC J-Lead configuration)
• Identical device type (EE PLD)
• Voltage supply compatibility within acceptable operating ranges

The ATF750CL-15JU qualifies as a direct substitute based on these parameters. Both devices share the same core architecture, pin configuration, and electrical performance characteristics. The primary distinction lies in product status, operating temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ATF750CL-15JU is the direct substitute for the obsolete ATF750CL-15JC. Selection between these devices depends on application requirements and compliance mandates:

ATF750CL-15JU is preferred for:

• New designs requiring active product support
• Applications mandating RoHS3 compliance
• Systems operating across extended temperature ranges (-40°C to 85°C)
• Designs requiring broader supply voltage tolerance (4.5V to 5.5V)

ATF750CL-15JC considerations:

• Legacy system maintenance where original specifications are locked
• Applications with restricted operating temperature requirements (0°C to 70°C)
• Systems with fixed supply voltage specifications (4.75V to 5.25V)

Both devices maintain identical functional performance, macrocell architecture, I/O configuration, and propagation delay characteristics. The ATF750CL-15JU offers enhanced environmental specifications and regulatory compliance, making it the recommended choice for new implementations.

Frequently Asked Questions (FAQ)

Q: Can ATF750CL-15JU directly replace ATF750CL-15JC in existing designs?

A: Yes. Both devices share identical macrocell count, I/O pin configuration, propagation delay, and package type. The ATF750CL-15JU operates across a wider temperature range and supply voltage window, providing enhanced compatibility with most applications.

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

A: The ATF750CL-15JC is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The ATF750CL-15JU maintains active production status, ensuring supply continuity and manufacturer support.

Q: Are there packaging differences between these devices?

A: Both devices use identical 28-LCC (J-Lead) surface mount packaging with 11.51x11.51mm dimensions. No PCB layout modifications are required for substitution.

Q: How do the operating temperature ranges affect substitution?

A: The ATF750CL-15JU supports -40°C to 85°C operation, compared to 0°C to 70°C for the ATF750CL-15JC. Applications operating within the narrower 0°C to 70°C window are compatible with both devices. Applications requiring extended temperature operation must use the ATF750CL-15JU.

Q: What is the impact of RoHS compliance differences?

A: The ATF750CL-15JU is ROHS3 compliant, while the ATF750CL-15JC is non-compliant. Applications subject to RoHS regulations must use the ATF750CL-15JU. Legacy systems without RoHS mandates may use either device.

Q: Do supply voltage ranges affect circuit design?

A: The ATF750CL-15JU accepts 4.5V to 5.5V, while the ATF750CL-15JC requires 4.75V to 5.25V. The ATF750CL-15JU provides broader tolerance, reducing voltage regulation requirements. Designs operating within 4.75V to 5.25V are compatible with both devices.
