Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC9572-10PC84C is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Programmable Type: In System Programmable with minimum 10K program/erase cycles
• Delay Time tpd(1) Max: 10 ns or faster
• Voltage Supply compatibility within acceptable operating ranges
• Mounting Type: Surface Mount
• Package Type: PLCC (Plastic Leaded Chip Carrier)

Secondary Compatibility Factors:

• Operating Temperature range overlap
• Number of macrocells and I/O pin count (functional capacity)
• RoHS and REACH compliance status
• Moisture Sensitivity Level classification

The ATF1504AS-10JU44 qualifies as a substitute based on matching the core programmable logic device specifications, including identical maximum propagation delay, compatible in-system programmability, surface mount configuration, and PLCC packaging. However, this substitute features reduced macrocell count (64 versus 72) and I/O pin count (32 versus 69), requiring design evaluation for functional equivalence in specific applications.

Engineering Selection Recommendations

Product Status Consideration: The XC9572-10PC84C is classified as obsolete, while the ATF1504AS-10JU44 maintains active product status with current manufacturing support. Selection of the active substitute ensures ongoing availability and supply chain stability.

Compliance and Certification: The ATF1504AS-10JU44 achieves ROHS3 compliance, whereas the XC9572-10PC84C is RoHS non-compliant. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the substitute provides regulatory alignment. Both devices maintain identical REACH and ECCN classifications.

Electrical Performance: Both devices deliver identical maximum propagation delay specifications of 10 nanoseconds, ensuring timing equivalence. The ATF1504AS-10JU44 operates across a broader voltage supply range (4.5V ~ 5.5V versus 4.75V ~ 5.25V) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), providing enhanced environmental flexibility.

Functional Capacity: The ATF1504AS-10JU44 provides 64 macrocells and 32 I/O pins compared to the XC9572-10PC84C's 72 macrocells and 69 I/O pins. Design applications requiring the full I/O capacity or maximum macrocell count of the original device cannot be directly substituted without architectural redesign.

Package Considerations: The substitute utilizes a 44-pin PLCC package (16.6x16.6 mm) versus the original 84-pin PLCC package (29.31x29.31 mm). PCB layout modifications are required for physical integration.

Frequently Asked Questions (FAQ)

Q: Can the ATF1504AS-10JU44 directly replace the XC9572-10PC84C in existing designs?

A: Direct replacement is not possible without design evaluation. The substitute features reduced I/O pin count (32 versus 69) and macrocell count (64 versus 72), requiring functional analysis to determine if the application requirements can be met within these constraints. Additionally, the package footprint differs significantly (44-pin versus 84-pin PLCC), necessitating PCB redesign.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are maximum propagation delay (both 10 ns), programmable type (both In System Programmable with 10K+ cycles), and voltage supply ranges. The ATF1504AS-10JU44 operates within a broader voltage window (4.5V ~ 5.5V) and temperature range (-40°C ~ 85°C), providing enhanced operational flexibility compared to the original device.

Q: Does the ATF1504AS-10JU44 meet modern environmental compliance standards?

A: Yes. The ATF1504AS-10JU44 is ROHS3 compliant, whereas the XC9572-10PC84C is RoHS non-compliant. Both devices maintain identical REACH and ECCN classifications (EAR99). For applications requiring RoHS compliance, the substitute satisfies regulatory requirements.

Q: What is the impact of the different package sizes on system integration?

A: The XC9572-10PC84C uses an 84-pin PLCC package (29.31x29.31 mm), while the ATF1504AS-10JU44 uses a 44-pin PLCC package (16.6x16.6 mm). The smaller footprint of the substitute reduces board space requirements but necessitates complete PCB layout redesign and potential modifications to signal routing and power distribution architecture.

Q: Are there any programming or firmware compatibility considerations?

A: Both devices support In System Programmable functionality with identical minimum program/erase cycle specifications (10K cycles). However, the reduced macrocell and I/O capacity of the substitute may require logic design modifications to accommodate the original firmware or configuration files.

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

A: Both the XC9572-10PC84C and ATF1504AS-10JU44 are classified as MSL 3 (168 Hours), indicating identical moisture handling and storage requirements during manufacturing and assembly processes.
