A42MX24-3TQ176I

Overview

The A42MX24-3TQ176I is a Field Programmable Gate Array (FPGA) from the MX series, manufactured by Microsemi Corporation. It features 36,000 system gates and supports up to 150 user-programmable I/O pins. The device operates with mixed-voltage supplies of 3V to 3.6V or 4.5V to 5.5V. It is housed in a 176-LQFP surface-mount package and functions within an operating temperature range of -40°C to +85°C. The component has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• High-capacity single-chip ASIC alternative with up to 54,000 system gates across the family.
• Supports mixed-voltage operation for both core and I/Os, including PCI-compliant interfaces.
• Includes configurable dual-port SRAM resources for embedded memory applications.

Applications

• Industrial control systems requiring robust programmable logic.
• Automotive electronics utilizing industrial temperature grade components.
• Military and aerospace platforms needing HiRel certified devices.

Procurement Notes

Verify part authenticity through authorized channels due to obsolescence status. Confirm RoHS compliance requirements as the device may be non-compliant. Check for valid MSL handling procedures before assembly. Ensure supply chain sources provide original manufacturer documentation to avoid counterfeit risks during replacement planning.

Selection Notes

Select this model when 36,000 system gates and 176-pin LQFP packaging are required. Compare against other MX variants if different I/O counts or speed grades are needed. Consider the -3 speed grade performance relative to system timing constraints. Evaluate thermal management needs for the TQFP package in enclosed environments.

Part Context

This component belongs to the Actel MX FPGA family, originally developed by Actel and acquired by Microsemi. The A42MX24 variant specifically offers 36,000 system gates. It is part of a broader lineup that includes various pin counts and speed grades, serving as a bridge between complex CPLDs and larger FPGAs.
