Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC9572-7PC84C is determined by compatibility across the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 84-pin PLCC package (29.31x29.31mm) to ensure mechanical and electrical fit on existing printed circuit boards.

Programmable Architecture: The substitute must support In System Programmable (ISP) functionality with a minimum of 10,000 program/erase cycles to maintain design flexibility and field reprogrammability.

Voltage Supply Range: The substitute must operate within overlapping or compatible supply voltage specifications to function in the same power distribution environment.

Operating Temperature Range: The substitute must support the application's thermal operating conditions.

Logic Density and I/O Count: The substitute must provide sufficient macrocells, gates, and I/O pins to accommodate the original design's logic requirements.

Regulatory Compliance: Substitutes are evaluated based on RoHS and REACH compliance status to meet current environmental and regulatory standards.

The ATF1504AS-10JU84 from Microchip Technology meets these substitution criteria within the constraints of its specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The XC9572-7PC84C is obsolete, while the ATF1504AS-10JU84 is active and currently manufactured. The active status of the substitute ensures ongoing availability and supply chain continuity.

Regulatory Compliance: The ATF1504AS-10JU84 is ROHS3 compliant, whereas the XC9572-7PC84C is RoHS non-compliant. For applications subject to RoHS requirements, the substitute provides compliance alignment with current environmental regulations.

Package Compatibility: Both devices use identical 84-pin PLCC packaging (29.31x29.31mm), ensuring direct mechanical compatibility on existing PCB layouts without redesign.

Electrical Parameter Differences: The ATF1504AS-10JU84 exhibits a maximum propagation delay of 10 nanoseconds compared to 7.5 nanoseconds for the XC9572-7PC84C. The substitute provides a wider voltage supply range (4.5V to 5.5V versus 4.75V to 5.25V) and an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C).

Logic Density Trade-off: The substitute provides 64 macrocells and 64 I/O pins compared to 72 macrocells and 69 I/O pins in the original part. Design verification is required to confirm that the reduced logic density and I/O count are sufficient for the intended application.

Programmable Characteristics: Both devices support In System Programmable functionality with identical minimum program/erase cycle specifications, maintaining design flexibility for field updates.

Frequently Asked Questions (FAQ)

Q: Can the ATF1504AS-10JU84 be used as a direct replacement for the XC9572-7PC84C?

A: The ATF1504AS-10JU84 is mechanically compatible due to identical 84-pin PLCC packaging. However, the reduced macrocell count (64 versus 72) and I/O pin count (64 versus 69) require design verification to confirm that the application logic fits within the substitute's capacity. The propagation delay difference (10 ns versus 7.5 ns) must also be evaluated against timing requirements.

Q: What are the key differences in electrical specifications?

A: The ATF1504AS-10JU84 operates with a wider voltage supply range (4.5V to 5.5V) and extended temperature range (-40°C to 85°C) compared to the XC9572-7PC84C (4.75V to 5.25V, 0°C to 70°C). The maximum propagation delay is 10 nanoseconds for the substitute versus 7.5 nanoseconds for the original part.

Q: Are both devices pin-compatible?

A: Both devices use 84-pin PLCC packages with identical physical dimensions (29.31x29.31mm). However, the pin assignments and functional allocations may differ. Detailed pinout verification against the specific application schematic is required before substitution.

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

A: The ATF1504AS-10JU84 provides 64 macrocells and 64 I/O pins compared to 72 macrocells and 69 I/O pins in the XC9572-7PC84C. Applications utilizing the full capacity of the original device may require design optimization or may not fit within the substitute's logic density. Logic synthesis and place-and-route analysis must confirm compatibility.

Q: How do the programmable characteristics compare?

A: Both devices support In System Programmable (ISP) functionality with a minimum of 10,000 program/erase cycles. This ensures equivalent field reprogrammability and design flexibility for both components.

Q: What is the significance of the RoHS compliance difference?

A: The XC9572-7PC84C is RoHS non-compliant, while the ATF1504AS-10JU84 is ROHS3 compliant. For applications subject to RoHS directives or customer requirements, the substitute provides regulatory alignment. Existing designs using the non-compliant original part may require documentation or exemption justification.

Q: Are there moisture sensitivity considerations?

A: Both devices have identical Moisture Sensitivity Level (MSL) ratings of 3 with a 168-hour floor life. Handling, storage, and reflow procedures are equivalent for both components.

Q: What is the product status implication?

A: The XC9572-7PC84C is obsolete, indicating discontinued manufacturing and limited availability. The ATF1504AS-10JU84 is active and currently produced, ensuring long-term supply availability and support.
