A42MX16-2TQG176

Overview

The A42MX16-2TQG176 is a Field Programmable Gate Array (FPGA) from the Microchip MX series. It features 24,000 system gates and 608 Logic Elements within a 176-TQFP package. The device supports dual voltage operation at 3V to 3.6V and 4.5V to 5.5V. It provides 140 I/O pins and operates within a commercial temperature range of 0°C to +70°C. The component utilizes CMOS technology and has a maximum operating frequency of 117MHz.

Feature Summary

• Supports non-volatile Flash-based configuration for instant-on functionality without external memory.
• Provides high-density logic resources with 24,000 system gates in a compact surface-mount package.
• Features robust design with radiation tolerance suitable for demanding environments.

Applications

• Industrial control systems requiring reliable programmable logic.
• Automotive electronics applications utilizing automotive-grade components.
• Aerospace and defense hardware needing radiation-hardened solutions.

Procurement Notes

Verify the specific suffix '2' indicates the commercial temperature grade (0°C to +70°C). Confirm the package type matches the 176-pin Thin Quad Flatpack requirement. Ensure compatibility with existing board layouts for the TQFP form factor before ordering.

Selection Notes

Select this model when 24K system gates are required with 140 available I/O lines. Choose the -2 speed grade for 117MHz performance. Opt for the TQG176 package if space constraints favor a 24x24mm footprint over other MX series options like CQFP or PQFP variants.

Part Context

This part belongs to the Microchip A42MX family of Flash FPGAs. It shares architectural similarities with the A42MX16-2TQG176I but differs in operating temperature range. The MX series is known for combining FPGA flexibility with Flash non-volatility, distinguishing it from SRAM-based competitors.

Replacement Considerations

The A42MX16-2TQG176I serves as a direct functional substitute with an extended industrial temperature range (-40°C to +85°C). Other MX series devices may offer different gate counts or pin configurations but require schematic review for compatibility.
