ATF750C-7PC Equivalent & Substitute Parts

Part Overview

The ATF750C-7PC 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 7.5 ns. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. The ATF750C-7PC operates within the 4.75V to 5.25V supply voltage range and is housed in a 24-pin DIP package suitable for through-hole mounting applications.

Substitute Part Grouping Explanation

Substitution of the ATF750C-7PC is determined by strict equivalence across the following critical parameters:

• Macrocell Count: 10 macrocells (functional logic capacity)
• I/O Pin Count: 10 I/O pins (interface capability)
• Propagation Delay: 7.5 ns maximum (timing performance)
• Supply Voltage Range: 4.75V ~ 5.25V (power compatibility)
• Operating Temperature: 0°C ~ 70°C (thermal operating window)
• Package Type: 24-DIP through-hole (physical and electrical interface)
• Device Type: EE PLD (programmable logic technology)

The ATF750C-7PX meets all these criteria and is therefore a direct functional equivalent. Both devices share identical electrical specifications, logic capacity, and physical packaging, enabling direct substitution in circuit designs.

Engineering Selection Recommendations

The ATF750C-7PX is the direct substitute for the obsolete ATF750C-7PC. Selection between these parts should be based on the following factors:

Product Status: The ATF750C-7PC is classified as obsolete, while the ATF750C-7PX maintains active product status. For new designs and ongoing production, the ATF750C-7PX is the appropriate selection.

Compliance and Certifications: The ATF750C-7PX is RoHS3 compliant, whereas the ATF750C-7PC is RoHS non-compliant. Both devices maintain REACH Unaffected status and share identical ECCN and HTSUS classifications. For applications subject to RoHS requirements, the ATF750C-7PX is mandatory.

Programmable Verification: The ATF750C-7PX is verified as programmable by DiGi-Electronics, while the ATF750C-7PC status is not verified. This verification provides additional assurance for programming operations.

Packaging: The ATF750C-7PX is supplied in tube packaging, whereas the ATF750C-7PC packaging specification is not defined. Both devices are functionally identical and pin-compatible.

Frequently Asked Questions (FAQ)

Q: Can the ATF750C-7PX directly replace the ATF750C-7PC in existing designs?

A: Yes. The ATF750C-7PX is a direct functional equivalent with identical electrical specifications, logic capacity (10 macrocells, 10 I/O), timing performance (7.5 ns), supply voltage range (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and 24-DIP package configuration. No circuit modifications are required.

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

A: The primary differences are product status (ATF750C-7PC is obsolete; ATF750C-7PX is active), RoHS compliance (ATF750C-7PC is non-compliant; ATF750C-7PX is RoHS3 compliant), and programmable verification status (ATF750C-7PX is verified). Electrical and functional specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both devices use the 24-DIP (0.300", 7.62mm) package with identical pinout and through-hole mounting configuration. PCB layout and socket compatibility are maintained.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is a regulatory requirement in many markets. The ATF750C-7PX's RoHS3 compliance ensures compatibility with environmental and regulatory standards, whereas the ATF750C-7PC does not meet these requirements.

Q: Can I use the ATF750C-7PC if I have existing inventory?

A: Existing inventory of the ATF750C-7PC can be used in applications without RoHS requirements. However, for new production and designs subject to RoHS regulations, transition to the ATF750C-7PX is necessary.

Q: Are the programming characteristics identical between these parts?

A: Both devices are EE PLD (Electrically Erasable Programmable Logic Devices) with identical programming technology. The ATF750C-7PX carries verified programmable status, providing additional assurance for programming operations.
