A42MX16-1TQG176

Overview

The A42MX16-1TQG176 is a flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series. It features 24,000 system gates and 608 logic elements within a 176-pin Thin Quad Flatpack (TQFP) package. The device supports dual voltage operation at 3V to 3.6V and 4.5V to 5.5V. It provides 140 general-purpose I/O pins and operates within a temperature range of -40°C to 85°C. The component utilizes non-volatile flash technology for configuration retention.

Feature Summary

• Non-volatile flash architecture eliminates the need for external configuration memory devices.
• In-system programmability allows for design updates without removing the component from the circuit board.
• Supports multiple low-voltage power supply standards for flexible interface compatibility.

Applications

• Industrial control systems requiring robust logic processing
• Automotive electronics applications with wide temperature requirements
• Communication infrastructure signal processing

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm speed grade and temperature range. Ensure the ordering part number matches the required package variant and environmental compliance status before procurement.

Selection Notes

Select this model when a mid-density FPGA solution with integrated flash configuration is required. Compare pin count and gate density against alternative MX series variants to ensure optimal resource utilization for the target application logic complexity.

Part Context

This component belongs to the Microchip A42MX family of flash FPGAs. It succeeds earlier Actel designs following the company's acquisition, maintaining architectural compatibility while offering updated manufacturing processes and extended industrial temperature specifications.

Replacement Considerations

Direct functional substitutes include the A42MX16-2TQG176I for higher speed grades or the A42MX16-TQG176A for commercial temperature ranges. Verify pinout compatibility and timing parameters before substituting.
