A42MX24-3PQG160

Overview

The A42MX24-3PQG160 is a non-volatile Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX family. It provides 36,000 system gates and 912 logic elements within a 160-pin PQFP package. The device supports mixed-voltage operation with core voltages of 3.3V or 5V and I/O voltages ranging from 4.75V to 5.25V. It features 125 user-programmable I/O pins and operates within a commercial temperature range of 0°C to +70°C. The architecture includes fast wide-decode circuitry and deterministic timing suitable for ASIC replacement applications.

Feature Summary

• Non-volatile Flash-based architecture eliminates the need for external configuration memory
• Supports mixed-voltage operation for flexible interface integration
• Provides deterministic, user-controllable timing for precise signal control
• Enables up to 100% resource utilization and pin locking for direct ASIC replacement

Applications

• Automotive electronic control units requiring single-chip ASIC alternatives
• Industrial automation systems needing deterministic timing and high reliability
• Aerospace and defense electronics utilizing radiation-tolerant or high-reliability variants

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notifications as discontinuance actions may affect long-term supply availability. Ensure proper handling procedures are followed due to humidity sensitivity requirements during storage and reflow soldering processes.

Selection Notes

Select this model when 36,000 system gates and 125 I/Os meet design requirements. Choose the -3 speed grade if timing constraints align with its performance characteristics. Consider the PQFP-160 package for surface-mount compatibility. Evaluate alternative MX family members if different gate counts or package types better suit specific board space or capacity needs.

Part Context

This component belongs to the Microchip Actel MX FPGA family, known for non-volatile Flash technology. It serves as a bridge between discrete logic and complex processors. The A42MX24 variant specifically targets mid-range complexity applications. It replaces custom ASICs in various industries by offering reprogrammability without configuration overhead.

Replacement Considerations

Direct substitutes include other A42MX24 variants with different speed grades or packages, such as A42MX24-2PQG160I or A42MX24-PL84A. Cross-reference pinouts and electrical specifications carefully before substitution.
