A42MX16-PQG160A

Overview

The A42MX16-PQG160A is a field-programmable gate array from the Microchip MX family, featuring 24,000 system gates and 608 logic elements. It provides 125 I/O pins within a PQFP-160 surface-mount package. The device operates at a nominal 5 V supply voltage with a range of 4.5 V to 5.5 V. It supports an industrial temperature range from -40°C to +125°C. The component includes humidity sensitivity classification and requires specific handling protocols during assembly.

Feature Summary

• Single-chip FPGA solution designed as a cost-effective alternative to multiple PALs, CPLDs, and FPGAs
• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Enables up to 100% resource utilization and pin locking for deterministic timing

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the current lifecycle status before procurement, as official documentation indicates End-of-Life notifications for this part number. Confirm RoHS compliance details and moisture sensitivity level requirements with the manufacturer or authorized distributors. Ensure that any substitute components maintain compatibility with the specified 5V operating voltage and PQFP-160 package dimensions to avoid redesign efforts.

Selection Notes

Select this model when a high-density FPGA with 24K system gates is required in a PQFP-160 package. It is suitable for designs needing industrial temperature stability (-40°C to +125°C) and mixed-voltage I/O capabilities. Consider the EOL status and plan for long-term supply chain risks or migration strategies if deploying in new production hardware.

Part Context

This component belongs to the Microchip A42MX16 series, which offers single-chip ASIC alternatives with up to 54,000 system gates across the family. The MX devices are engineered to consolidate logic previously implemented in multiple discrete programmable devices, reducing board space and design complexity while maintaining high performance at 5V.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the End-of-Life notification, engineers should consult Microchip's official obsolescence management resources for recommended migration paths or equivalent newer generation devices.
