A42MX09-PQG144M

Overview

The A42MX09-PQG144M is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 14,000 system gates and 336 logic elements within a 144-pin PQFP package. The device supports mixed-voltage operation with core and I/O supplies ranging from 3V to 3.6V or 4.75V to 5.25V. It offers 95 user-programmable I/O pins and operates within a commercial temperature range of 0°C to +70°C. The component is classified as obsolete.

Feature Summary

• Single-chip ASIC alternative capability for designs requiring up to 54,000 system gates
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O supplies
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking

Applications

• Replacement for complex programmable logic devices in industrial control systems
• Prototyping for custom ASIC implementations
• Interface bridging between different voltage domains in embedded systems

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Buyers must confirm the specific suffix 'M' indicates military temperature grading if required, though standard datasheets list commercial ranges. Ensure compliance with RoHS3 standards during acquisition.

Selection Notes

Select this part when a dense FPGA solution with deterministic timing is needed to replace fixed-function ASICs. The PQG144 package provides a balance of I/O count and pin density. Consider the mixed-voltage capability if interfacing with legacy 5V logic while utilizing lower voltage cores. Verify that the 14,000 gate count meets the design complexity requirements before finalizing the selection.

Part Context

The A42MX09 belongs to the Actel/Microchip MX family of flash-based FPGAs, originally developed by Actel before its acquisition by Microchip. This series is known for non-volatile configuration and radiation tolerance options. The A42MX09 variant specifically targets mid-density applications, offering a cost-effective alternative to ASICs for low-to-medium volume production runs.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the obsolete status of the A42MX09 series. Designers should evaluate newer Microchip PolarFire or Igloo2 families for functional equivalents, noting differences in architecture and toolchain compatibility.
