ATF750CL-15PC Equivalent & Substitute Parts

Part Overview

The ATF750CL-15PC is a Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology, featuring 10 macrocells and 10 I/O pins with a maximum propagation delay of 15 nanoseconds. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. The ATF750CL-15PU serves as a direct substitute, offering identical core functionality within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The ATF750CL-15PU qualifies as a direct substitute for the ATF750CL-15PC based on the following alignment of critical parameters:

• Programmable Type: Both devices are EE PLD (Electrically Erasable Programmable Logic Device)
• Macrocell Count: Identical at 10 macrocells
• I/O Pin Count: Identical at 10 I/O pins
• Propagation Delay: Both specify 15 ns maximum tpd(1)
• Package Configuration: Both use 24-DIP (0.300", 7.62mm) with 24-PDIP supplier packaging
• Mounting Technology: Both employ through-hole mounting

These parameters define the functional and physical compatibility required for direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The ATF750CL-15PU is the appropriate substitute for the obsolete ATF750CL-15PC. The substitute device maintains identical core specifications for macrocell count, I/O configuration, and timing performance. The ATF750CL-15PU offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and wider supply voltage tolerance (4.5V to 5.5V versus 4.75V to 5.25V), providing enhanced operational flexibility. The substitute carries Active product status and ROHS3 compliance, addressing regulatory and supply chain continuity requirements that the obsolete part cannot satisfy.

Frequently Asked Questions (FAQ)

Q: Can the ATF750CL-15PU directly replace the ATF750CL-15PC in existing designs?

A: Yes. Both devices share identical macrocell count (10), I/O pin count (10), propagation delay (15 ns maximum), and 24-DIP package configuration. The physical and functional compatibility supports direct substitution.

Q: What are the differences between these two parts?

A: The primary differences are product status, compliance certifications, and operational ranges. The ATF750CL-15PU is Active (versus Obsolete), ROHS3 compliant (versus non-compliant), and operates across -40°C to 85°C (versus 0°C to 70°C). Supply voltage tolerance is also wider: 4.5V to 5.5V versus 4.75V to 5.25V.

Q: Are there packaging differences?

A: No. Both devices use identical 24-DIP (0.300", 7.62mm) through-hole packaging with 24-PDIP supplier configuration. PCB layout and socket compatibility remain unchanged.

Q: Why is the ATF750CL-15PC listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The ATF750CL-15PU remains in active production and serves as the current equivalent for this device family.

Q: Does the extended temperature range of the ATF750CL-15PU affect compatibility?

A: No. The extended range (-40°C to 85°C) is a superset of the original specification (0°C to 70°C). Designs operating within the original temperature window remain fully compatible.

Q: Are regulatory certifications important for my application?

A: Regulatory requirements depend on your end-use application and target markets. The ATF750CL-15PU's ROHS3 compliance and REACH Unaffected status address environmental and hazardous substance regulations applicable to many industries and regions.
