A42MX16-2PQG100

Overview

The A42MX16-2PQG100 is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip A42MX family, designed as a single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 2000 system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. It operates within an extended temperature range of -55°C to +125°C and utilizes a 100-pin Plastic Quad Flat Package (PQFP). Key specifications include mixed-voltage operation for core and I/Os, up to 202 user-programmable I/O pins, and support for deterministic timing with 100% resource utilization and pin locking capabilities.

Feature Summary

• High-density logic architecture providing a scalable single-chip ASIC replacement solution
• Extended industrial and military temperature rating for harsh environment reliability
• Mixed-voltage I/O capability supporting both 5.0V and 3.3V standards

Applications

• Military and aerospace avionics systems requiring radiation-tolerant or high-reliability programmable logic
• Industrial control applications operating in extreme thermal conditions
• Automotive electronics demanding robust performance across wide temperature ranges

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as A42MX16-2PQG100A denote commercial-grade components which differ in temperature range from the -2 military grade specified here. Confirm package authenticity and moisture sensitivity level handling procedures prior to assembly. Ensure compatibility with existing design tools for the A42MX family before procurement.

Selection Notes

Select this component when designing for environments requiring operation below -40°C or above +85°C. Compare against the A42MX16-2PQ100A if the application is limited to commercial temperatures (-40°C to +85°C), as the latter may offer different availability or cost structures. Ensure the 100-pin PQFP footprint fits the PCB layout constraints.

Part Context

This part belongs to the Actel/Microchip A42MX FPGA family, which bridges the gap between standard PLDs and complex FPGAs. The '2' suffix indicates the military temperature grade, distinguishing it from commercial ('A') and industrial ('I') variants within the same logical capacity. These devices are known for non-volatile flash technology, eliminating the need for external configuration memory.

Replacement Considerations

Direct functional replacements within the same package and speed grade are limited due to the specific military temperature rating. Consider the A42MX16-2PQ100A only if the thermal environment allows for commercial-grade operation. Cross-family migration to newer Microchip PolarFire or IGLOO2 series requires significant schematic and software redesign.
