ATF1500ABV-15AI Equivalent & Substitute Parts

Part Overview

The ATF1500ABV-15AI is a 32-macrocell Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology, housed in a 44-pin TQFP package with 15 nanosecond propagation delay. This device is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations. The ATF15xx series provides in-system programmability with a minimum of 10,000 program/erase cycles, supporting both 3V and 5.25V supply voltage ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF1500ABV-15AI is determined by the following critical parameters:

• Macrocell and I/O Count: Both main and substitute parts must provide 32 macrocells and 32 I/O pins to maintain functional equivalence
• Propagation Delay: Maximum tpd(1) of 15 ns ensures timing compatibility
• Package Type: 44-TQFP (10x10) surface mount package maintains PCB layout compatibility
• Programmability: In-system programmability with minimum 10K program/erase cycles
• Operating Temperature Range: -40°C ~ 85°C (TA) for thermal environment compatibility
• Voltage Supply Range: Internal supply voltage compatibility within specified ranges

The ATF1502ASV-15AU44 qualifies as a direct substitute based on matching macrocell count, I/O configuration, propagation delay, package type, and programmability specifications. Voltage supply range differences are noted but do not preclude substitution in applications operating within the overlapping voltage window.

Parameter Comparison

Engineering Selection Recommendations

The ATF1502ASV-15AU44 is the qualified substitute for the obsolete ATF1500ABV-15AI. Selection rationale is based on the following factors:

Product Status: The ATF1502ASV-15AU44 maintains active product status with Microchip Technology, ensuring continued availability and manufacturing support compared to the obsolete ATF1500ABV-15AI.

Compliance and Certifications: The ATF1502ASV-15AU44 is ROHS3 compliant, whereas the ATF1500ABV-15AI is RoHS non-compliant. Both devices maintain REACH Unaffected status and EAR99 ECCN classification.

Voltage Supply Consideration: The ATF1502ASV-15AU44 operates within a reduced voltage supply range of 3V ~ 3.6V compared to the ATF1500ABV-15AI range of 3V ~ 5.25V. Applications requiring 5V operation must verify compatibility with the substitute part's 3.6V maximum specification.

Functional Equivalence: Identical macrocell count (32), I/O configuration (32), propagation delay (15 ns), package type (44-TQFP), and programmability specifications ensure functional compatibility for logic design implementations.

Frequently Asked Questions (FAQ)

Q: Can the ATF1502ASV-15AU44 directly replace the ATF1500ABV-15AI in existing designs?

A: Direct replacement is possible for applications operating within the 3V ~ 3.6V supply voltage range. Designs requiring 5V operation must be evaluated against the substitute part's maximum 3.6V specification. All other functional parameters—macrocell count, I/O configuration, propagation delay, and package type—are identical.

Q: What is the primary reason for substitution?

A: The ATF1500ABV-15AI is classified as obsolete. The ATF1502ASV-15AU44 provides equivalent functionality with active product status and improved compliance (ROHS3).

Q: Are there package compatibility concerns?

A: Both parts use identical 44-TQFP (10x10) surface mount packaging. PCB layout and footprint compatibility is maintained without modification.

Q: How do the programmability specifications compare?

A: Both devices support in-system programmability with a minimum of 10,000 program/erase cycles, ensuring equivalent programming capability and flexibility.

Q: What compliance differences exist between these parts?

A: The ATF1502ASV-15AU44 is ROHS3 compliant, while the ATF1500ABV-15AI is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 ECCN classification.

Q: Is the voltage supply range difference critical for substitution?

A: The voltage supply range difference is application-dependent. The ATF1502ASV-15AU44 maximum of 3.6V is lower than the ATF1500ABV-15AI maximum of 5.25V. Applications operating exclusively within the 3V ~ 3.6V window experience no impact. Applications requiring higher voltage operation require design verification.
