A42MX16-VQG100M

Overview

The A42MX16-VQG100M is a field-programmable gate array (FPGA) from the Microchip MX series, housed in a 100-pin VQFP package. It features 24,000 system gates and 608 logic elements with 83 user-programmable I/O pins. The device operates on mixed-voltage supplies of 3V to 3.6V or 4.5V to 5.5V. It supports an operating temperature range of -55°C to +125°C and has a moisture sensitivity level of 3.

Feature Summary

• Single-chip ASIC alternative offering high capacity and performance
• Supports mixed-voltage operation for core and I/Os
• Enables up to 100% resource utilization and pin locking
• Provides deterministic, user-controllable timing

Applications

• High-speed controllers
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix M against official Microchip documentation to confirm it denotes military-grade qualification or extended temperature ranges, as suffixes can indicate variations in testing standards. Ensure compatibility with existing PCB footprints for the 100-VQFP package before procurement.

Selection Notes

Select this model when a high-density FPGA solution is required for harsh environments due to its wide industrial and military temperature rating. Consider the 24,000 system gate capacity and 83 I/O count to ensure sufficient resources for the target design complexity without over-provisioning.

Part Context

This component belongs to the A42MX16 family within the broader MX FPGA portfolio. It serves as a high-capacity programmable logic device designed to replace multiple discrete logic components. The VQG100M variant specifically utilizes a thin quad flatpack no-lead package suitable for surface-mount assembly.

Replacement Considerations

Direct replacements include other variants within the A42MX16 family such as A42MX16-VQG100A, provided the package and electrical specifications match. Verify that any substitute maintains the required MIL-STD-883 or QML certification if applicable.
