A42MX24-TQ176I

Overview

The A42MX24-TQ176I is an MX series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a capacity of 36,000 system gates and supports up to 150 user-programmable I/O pins. The device operates within a supply voltage range of 3V to 3.6V or 4.5V to 5.5V. It is housed in a 176-LQFP surface-mount package with dimensions of 24x24 mm. The component supports an operating temperature range of -40°C to 85°C (TA). Moisture Sensitivity Level (MSL) is rated at 3, corresponding to 168 hours. The part status is listed as Obsolete.

Feature Summary

• Single-chip ASIC alternative architecture supporting synthesis-friendly design methodologies
• Mixed-voltage operation capability for core and I/Os with PCI-compliant interfaces
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Industrial control systems utilizing mixed-voltage logic
• Military and aerospace environments compatible with commercial plastic packages

Procurement Notes

Verify the obsolete status and RoHS non-compliance before integration. Confirm that the 176-LQFP package dimensions match the target PCB footprint. Check for available EOL notifications or PCN documents from Microchip Technology to assess long-term availability risks. Ensure design tools support the legacy MX FPGA family.

Selection Notes

Select this model when 36,000 system gates and 150 I/Os are required in a 176-pin form factor. Consider the industrial temperature range (-40°C to 85°C) for harsh environments. Verify compatibility with 3.3V or 5V supply rails. Note that this specific suffix denotes the industrial grade variant within the TQ176 package.

Part Context

This component belongs to the Microsemi MX FPGA family, originally developed by Actel. The A42MX24 variant provides 36,000 system gates, positioning it between lower-density models like the A42MX16 and higher-density options. The TQ176 suffix indicates a Thin Quad Flat Package with 176 leads, suitable for high-density surface mount assembly.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the obsolete status. Review the broader A42MX24 family for similar package options if functional equivalence is required.
