A42MX24-2TQ176I

Overview

The A42MX24-2TQ176I is an MX series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a capacity of 36,000 system gates and 912 Logic Elements within a 176-pin Thin Quad Flat Package (TQFP). The device supports mixed-voltage operation with supply ranges of 3V to 3.6V and 4.5V to 5.5V. It operates within a temperature range of -40°C to 85°C and includes up to 150 user-programmable I/O pins.

Feature Summary

• Functions as a high-capacity single-chip ASIC alternative with deterministic timing.
• Supports mixed-voltage core and I/O operations compatible with PCI standards.
• Includes configurable dual-port SRAM for fast access and FIFO applications.

Applications

• Industrial control systems requiring robust programmable logic
• Automotive electronics utilizing industrial temperature grade components
• Military applications necessitating specific radiation or reliability certifications

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be subject to obsolescence notices from the manufacturer. Confirm that the specific suffix corresponds to the required industrial temperature rating and package variant. Ensure compliance with RoHS and REACH regulations relevant to the production batch. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the design requirements.

Selection Notes

Select this model when a dense FPGA solution in a TQFP package is required for space-constrained designs. Compare against other MX family members based on gate count and I/O availability. Verify that the 176-pin footprint aligns with the PCB layout constraints. Consider the mixed-voltage capability if interfacing with both 3.3V and 5V logic domains without level shifters.

Part Context

This part belongs to the Microsemi MX FPGA family, designed to replace complex discrete logic or standard ASICs. The A42MX24 variant specifically offers 36,000 system gates, positioning it between lower-density models like the A42MX16 and higher-density options. It utilizes Actel's flash-based technology, allowing non-volatile configuration storage.

Replacement Considerations

Direct replacements include other variants within the A42MX24 family such as the A42MX24-3TQ176B or A42MX24-TQ176I, provided the speed grade and temperature range are compatible. Check for updated packages like the TQG176 if ball grid array form factors are acceptable.
