A42MX16-1PQ160I

Overview

The A42MX16-1PQ160I is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 24,000 system gates and 608 logic elements within a PQFP-160 package. The device supports dual voltage operation at 3.3 V and 5 V, with supply voltage ranges of 4.5 V to 5.5 V for 5V mode and 3.0 V to 3.6 V for 3.3V mode. It offers 140 I/O pins and operates within a temperature range of -40°C to +85°C. The component utilizes anti-fuse technology for non-volatile configuration.

Feature Summary

• Utilizes anti-fuse technology for permanent, secure configuration without volatile memory requirements.
• Supports mixed-mode I/O interfaces compatible with both 3.3 V and 5 V logic levels.
• Integrates high-speed serial transceivers for communication applications.
• Includes dedicated hardware security features to protect intellectual property.

Applications

• Industrial control systems requiring secure, non-volatile programmability
• Automotive electronics operating in harsh environmental conditions
• Aerospace and defense communication protocols
• Test and measurement equipment interface logic

Procurement Notes

Verify the specific speed grade suffix and package variant against the official Microchip datasheet DS2316. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to ordering. Ensure the supplier provides traceability documentation consistent with aerospace or industrial standards if required for the application.

Selection Notes

Select this model when a moderate gate count with robust security features is needed. Compare pin counts and I/O voltage compatibility against alternative MX series variants. Consider the PQFP-160 footprint constraints during PCB layout. Verify thermal performance requirements against the specified junction-to-ambient characteristics for the chosen enclosure.

Part Context

This component belongs to the A42MX family of low-power, high-density FPGAs. It shares architectural similarities with the A42MX24 but offers reduced gate density. The MX series is distinguished by its anti-fuse process, which eliminates the need for external configuration memory devices commonly used in SRAM-based FPGAs.

Replacement Considerations

Direct substitutes include other A42MX16 variants with different packages such as A42MX16-PQG100I or A42MX16-2TQG176I. Cross-family replacements may require significant schematic and firmware modifications due to architectural differences between anti-fuse and SRAM-based FPGA technologies.
