A42MX24-TQG176M

Overview

The A42MX24-TQG176M is a non-volatile Field Programmable Gate Array (FPGA) from the Microchip MX family. It features 36,000 system gates and 912 Logic Elements within a 176-pin Thin Quad Flat Package (TQFP). The device operates at supply voltages of 3.3V or 5V, with specific ranges of 3.0V to 3.6V for low voltage and 4.75V to 5.25V for standard voltage. It supports up to 150 I/O pins and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile flash-based architecture eliminates configuration memory requirements.
• Supports both 3.3V and 5V power domains for flexible interface compatibility.
• High-density logic resources suitable for complex digital control applications.

Applications

• Industrial automation controllers
• Telecommunications infrastructure equipment
• Automotive electronic systems

Procurement Notes

Verify the suffix 'M' indicates military-grade temperature rating (-40°C to +85°C) against the official datasheet. Confirm RoHS compliance status as historical data varies by production batch. Ensure the TQFP-176 package dimensions match the target PCB footprint design constraints.

Selection Notes

Compare gate counts and I/O availability against lower-density models like the A42MX16 if resource optimization is required. Evaluate speed grades such as -2 or -3 variants based on timing closure requirements. Consider pinout compatibility with existing designs when selecting alternative packages in the same series.

Part Context

This component belongs to the Actel/Microsemi MX FPGA family, known for instant-on capabilities due to embedded flash technology. It bridges the gap between CPLDs and high-end FPGAs, offering moderate density with robust security features and radiation tolerance characteristics typical of this product line.

Replacement Considerations

Direct substitutes include other speed grades within the A42MX24 series, such as A42MX24-2TQG176 or A42MX24-3TQG176, provided timing specifications are met. Cross-referencing pin-compatible devices within the broader MX family may be necessary if specific speed grades are unavailable.
