A40MX02-VQG80M

Overview

The A40MX02-VQG80M is a field-programmable gate array from the Microchip MX series, featuring 295 logic elements and approximately 3,000 system gates. It provides 57 user-programmable I/O pins within an 80-pin VQFP package. The device supports mixed-voltage operation with supply voltage ranges of 4.5V to 5.5V for standard operation and 3.3V or 5V for core and I/O configurations. It operates reliably across an extended industrial temperature range from -55°C to +125°C. This component utilizes flash-based non-volatile technology, eliminating the need for external configuration memory.

Feature Summary

• Flash-based architecture enabling instant-on functionality without external configuration devices
• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5V systems
• Extended temperature rating suitable for demanding industrial and automotive environments
• Deterministic timing characteristics with user-controllable resource utilization

Applications

• Industrial control systems requiring reliable operation in harsh thermal conditions
• Automotive electronics applications certified for extended temperature ranges
• Military and aerospace embedded systems utilizing commercial plastic packages
• Low-volume ASIC prototyping and replacement scenarios

Procurement Notes

Verify the specific suffix M against official Microchip documentation to confirm the exact temperature grade and package variant. Confirm moisture sensitivity level requirements for your assembly process. Ensure the design accounts for the specified voltage ranges. Check for any recent product change notices regarding packaging or assembly sites. Validate that the 80-pin VQFP footprint matches your PCB layout constraints.

Selection Notes

Select this part when 295 logic elements are sufficient for the design complexity. Choose the VQG80M package for surface-mount applications requiring 57 I/Os. Consider the -55°C to +125°C range if operating in extreme environments. Compare against other MX family members if higher gate counts or different pinouts are needed. Verify compatibility with existing FPGA design tools and programming hardware.

Part Context

This component belongs to the A40MX02 family within the broader MX FPGA portfolio. It shares architectural similarities with variants like the A40MX02-PLG68I but offers a different pin count and package style. The family is known for high-density logic in small footprints. It serves as a drop-in replacement for older GALs and CPLDs in many legacy designs.

Replacement Considerations

Direct substitutes include other A40MX02 variants with compatible pinouts, such as the A40MX02-PLG68I for PLCC-68 packages. Cross-reference pin assignments carefully when moving between different package types within the same logic family. Ensure software compatibility with the Actel Libero IDE for reprogramming.
