A42MX24-1TQG176

Overview

The A42MX24-1TQG176 is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 36,000 system gates and 912 logic elements within a 176-pin TQFP package. The device supports dual voltage supplies: 3V to 3.6V for core logic and 4.5V to 5.5V for I/O interfaces. It offers 150 general-purpose I/Os and operates within an industrial temperature range of -40°C to +85°C. The component is RoHS compliant and classified under ECCN 3A991D.

Feature Summary

• Non-volatile flash-based architecture providing instant-on functionality without external configuration memory.
• High-density programmable logic with 36K system gates suitable for complex digital designs.
• Dual-voltage operation supporting both 3.3V and 5V I/O standards for flexible interface compatibility.

Applications

• Industrial control systems requiring reliable non-volatile programmable logic.
• Automotive electronics applications operating within extended temperature ranges.
• Communication infrastructure equipment utilizing high-speed serial interfaces.

Procurement Notes

Verify the specific speed grade suffix '1' against official Microchip documentation to confirm timing characteristics. Confirm the package type is 176-TQFP with a 24x24mm footprint. Check for any recent Product Change Notifications regarding manufacturing location or material composition updates before finalizing procurement specifications.

Selection Notes

Select this part when a non-volatile FPGA with 36K gates is required in a 176-pin TQFP package. Ensure the design utilizes the specified dual voltage rails of 3.3V and 5V. Compare against the A42MX24-3TQG176 if higher speed performance is needed, noting that the '1' suffix indicates a specific timing grade within the MX family.

Part Context

This component belongs to the Actel/Microchip MX family of flash FPGAs, known for their security and instant-on capabilities. It serves as a mid-range solution in the portfolio, bridging lower-density parts like the A42MX16 and higher-density options. The TQG176 designation identifies the specific thermal and pin-compatible variant within the broader A42MX24 product line.

Replacement Considerations

The A42MX24-3TQG176 is a verified faster-speed variant within the same package and logic density. Other MX family members share architectural similarities but differ in gate counts and I/O configurations. Verify pin-to-pin compatibility and timing requirements before substituting with other A42MX24 variants.
