Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC9572-10PCG44C is determined by the following critical parameters:

Physical Compatibility:

• Package type: 44-LCC (J-Lead) with 44-PLCC footprint
• Mounting type: Surface Mount
• Physical dimensions: 16.59mm x 16.59mm (or equivalent)

Electrical Compatibility:

• Delay time tpd(1) Max: 10 ns or faster
• Voltage supply range: Must accommodate 4.75V ~ 5.25V operation
• Programmable type: In System Programmable capability required
• Minimum program/erase cycles: 10K or greater

Functional Compatibility:

• Logic capacity: Macrocells and I/O pin count must meet or exceed the original specification
• Number of I/O: Minimum 34 pins required
• Number of Macrocells: Minimum 72 macrocells required

The ATF1504AS-10JU44 meets these substitution criteria through equivalent package specifications, matching propagation delay, compatible voltage supply range, and sufficient logic capacity within the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

The ATF1504AS-10JU44 serves as a functional substitute for the XC9572-10PCG44C based on the following engineering criteria:

Package and Physical Compatibility: Both devices utilize identical 44-LCC (J-Lead) packaging with 44-PLCC footprints and surface mount mounting type, ensuring direct PCB compatibility without layout modifications.

Electrical Performance: The substitute maintains the same 10 nanosecond maximum propagation delay specification, meeting timing requirements. The ATF1504AS-10JU44 operates within a wider voltage supply range (4.5V ~ 5.5V) that fully encompasses the original device's 4.75V ~ 5.25V specification, ensuring voltage compatibility across all operating conditions.

Programmability and Reliability: Both devices support In System Programmable functionality with minimum 10K program/erase cycles, maintaining design flexibility and field reprogrammability. Moisture sensitivity levels are identical at MSL 3 (168 Hours).

Product Status and Compliance: The ATF1504AS-10JU44 is an active product currently in production, providing long-term availability and supply chain stability. The substitute meets ROHS3 compliance requirements, supporting modern environmental and regulatory standards.

Logic Capacity Considerations: The substitute contains 64 macrocells and 32 I/O pins compared to the original 72 macrocells and 34 I/O pins. Design verification is required to confirm that the reduced logic capacity and I/O count are sufficient for the specific application implementation.

Frequently Asked Questions (FAQ)

Q: Can the ATF1504AS-10JU44 be used as a direct replacement for the XC9572-10PCG44C without PCB modifications?

A: Yes, both devices share identical 44-LCC (J-Lead) packaging with 44-PLCC footprints and surface mount specifications. PCB layout compatibility is maintained. However, the reduced I/O pin count (32 versus 34) and macrocell count (64 versus 72) require design verification to ensure functional requirements are met.

Q: What are the key differences between these two devices?

A: The primary differences are: (1) Macrocell count: XC9572 has 72 macrocells; ATF1504 has 64 macrocells; (2) I/O pin count: XC9572 has 34 I/O pins; ATF1504 has 32 I/O pins; (3) Operating temperature range: XC9572 operates 0°C ~ 70°C; ATF1504 operates -40°C ~ 85°C; (4) Product status: XC9572 is obsolete; ATF1504 is active production.

Q: Are the voltage supply specifications compatible?

A: Yes. The ATF1504AS-10JU44 operates at 4.5V ~ 5.5V, which fully overlaps and exceeds the XC9572-10PCG44C specification of 4.75V ~ 5.25V. The substitute accommodates all voltage conditions required by the original design.

Q: Does the substitute meet modern compliance standards?

A: The ATF1504AS-10JU44 is ROHS3 compliant and meets current environmental regulations. Both devices are REACH Unaffected and carry EAR99 ECCN classification.

Q: What is the impact of reduced macrocell and I/O count on design implementation?

A: The ATF1504AS-10JU44 provides 8 fewer macrocells and 2 fewer I/O pins than the original device. Design verification is required to confirm that the reduced logic capacity and I/O availability do not exceed the substitute's specifications for the intended application.

Q: Are both devices programmable in the same manner?

A: Yes. Both devices support In System Programmable (ISP) functionality with identical minimum program/erase cycle specifications of 10K cycles, maintaining design flexibility and field reprogrammability.

Q: What is the moisture sensitivity level for both devices?

A: Both devices carry an MSL rating of 3 (168 Hours), indicating identical moisture handling and storage requirements.
