ATF750LVC-15SC Equivalent & Substitute Parts

Part Overview

The ATF750LVC-15SC is a 10-macrocell Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology, housed in a 24-SOIC surface mount package. This device operates with a maximum propagation delay of 15 nanoseconds and supports voltage supplies between 3V and 5.25V. The ATF750LVC-15SC is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF750LVC-15SC is determined by the following critical parameters:

• Programmable Type: Must be EE PLD (Electrically Erasable Programmable Logic Device)
• Macrocell Count: Must equal 10 macrocells
• I/O Count: Must equal 10 I/O pins
• Propagation Delay: Must not exceed 15 ns maximum
• Voltage Supply Range: Must encompass or match the 3V to 5.25V operating window
• Package: Must be 24-SOIC form factor with identical pin pitch and dimensions
• Mounting Type: Must be Surface Mount

The ATF750LVC-15SU meets all substitution criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ATF750LVC-15SU is a direct functional equivalent to the ATF750LVC-15SC. Both devices share identical core specifications: 10 macrocells, 10 I/O pins, 15 ns maximum propagation delay, and 24-SOIC packaging. The ATF750LVC-15SU offers operational advantages including an extended voltage supply range (3V to 5.5V versus 3V to 5.25V) and broader operating temperature range (-40°C to 85°C versus 0°C to 70°C).

The primary distinction is product status: the ATF750LVC-15SC is obsolete, while the ATF750LVC-15SU is active and currently in stock. For new designs or system replacements, the ATF750LVC-15SU is the appropriate selection. Both devices comply with ECCN EAR99 and HTSUS 8542.39.0001 classifications.

Frequently Asked Questions (FAQ)

Q: Can the ATF750LVC-15SU directly replace the ATF750LVC-15SC in existing designs?

A: Yes. Both devices are pin-compatible 24-SOIC packages with identical macrocell and I/O counts, propagation delay specifications, and core voltage supply requirements. No circuit modifications are required.

Q: What is the significance of the different voltage supply ranges?

A: The ATF750LVC-15SU supports 3V to 5.5V, while the ATF750LVC-15SC supports 3V to 5.25V. The substitute's wider range provides additional design margin and is fully compatible with applications designed for the original part.

Q: Does the extended operating temperature range of the ATF750LVC-15SU affect compatibility?

A: No. The substitute's extended range (-40°C to 85°C) encompasses the original specification (0°C to 70°C). Applications operating within the original temperature window remain fully compatible.

Q: Are there any compliance or certification differences between these parts?

A: Both devices share identical ECCN and HTSUS classifications. The ATF750LVC-15SC is RoHS non-compliant with MSL 1, while the ATF750LVC-15SU's compliance status is not specified in the provided data.

Q: Why is the ATF750LVC-15SC classified as obsolete?

A: Obsolescence indicates the part is no longer manufactured by the original supplier. The ATF750LVC-15SU, manufactured by Atmel and currently active, serves as the available alternative within the ATF750LVC series.
