A42MX24-2TQG176

Overview

The A42MX24-2TQG176 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and 912 logic elements within a TQFP-176 package. The device supports mixed-voltage operation with core voltages of 3.3 V or 5 V and I/Os compatible with 5.0 V or 3.3 V standards. Electrical specifications include a minimum supply voltage of 4.75 V and a maximum of 5.25 V for the 5 V variant, or 3.0 V to 3.6 V for the 3.3 V variant. It operates within an industrial temperature range of 0°C to +70°C.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration of 5.0 V and 3.3 V components on the same board.
• Provides deterministic, user-controllable timing suitable for precise signal processing applications.
• Includes unique in-system diagnostic capability via Silicon Explorer II for verification.

Applications

• Automotive electronic control units requiring high reliability and low power consumption.
• Industrial automation systems needing deterministic timing and robust I/O interfaces.
• Aerospace and defense electronics utilizing radiation-hardened or high-reliability FPGA architectures.

Procurement Notes

Verify the specific speed grade suffix and voltage variant during procurement, as these determine electrical characteristics and availability. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for end-of-life notifications or product change notices that may affect long-term supply stability.

Selection Notes

Select this model when 36K system gates and 150 I/O pins are required in a TQFP-176 footprint. Ensure the design utilizes either 3.3 V or 5 V core voltage, as mixing core supplies is not supported. Verify that the target application fits within the 912 logic element capacity and does not require embedded memory blocks beyond the configurable dual-port SRAM options.

Part Context

This component belongs to the Microchip MX FPGA series, which bridges the gap between discrete logic and custom ASICs. The A42MX24 variant specifically offers 36,000 system gates, positioning it for medium-complexity designs. The TQG176 suffix indicates the 176-pin Thin Quad Flat Package with a grid array configuration, optimized for surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to specific gate counts and speed grades. Consider the A42MX24-TQG176A or A42MX24-3TQG176 if speed grade variations are acceptable. For higher density needs, evaluate the A42MX54 series, though pin compatibility must be verified against the specific package variant.
