A40MX04-VQG80A

Overview

The A40MX04-VQG80A is a field-programmable gate array from the Microchip MX series, featuring approximately 6,000 system gates and 547 logic elements. It provides 69 user-programmable I/O pins within an 80-pin VQFP package. The device supports mixed-voltage operation with core and I/O supplies ranging from 4.5V to 5.5V. It operates reliably across a commercial temperature range of -40°C to +125°C. This non-volatile FPGA utilizes flash technology for instant-on configuration without external memory.

Feature Summary

• Instant-on capability due to non-volatile flash architecture eliminating the need for external configuration devices
• Supports mixed-voltage operation allowing flexible interface compatibility with various system components
• High-density programmable logic structure suitable for complex digital design implementations

Applications

• Industrial control systems requiring reliable logic processing
• Automotive electronics applications operating in harsh thermal environments
• Military and aerospace systems utilizing radiation-hardened or high-reliability variants

Procurement Notes

Verify the specific suffix 'A' against official datasheets to confirm it denotes the commercial temperature grade (-40°C to +125°C) rather than a different voltage or package variant. Ensure the ordering part number matches the exact pin count and package dimensions required by the PCB footprint. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.

Selection Notes

Select this component when a non-volatile FPGA with instant-on functionality is required for designs needing approximately 6,000 system gates. The VQFP-80 package offers a compact surface-mount solution for moderate I/O counts. Consider the 5V supply requirement and ensure the design accommodates the specified voltage ranges for both core and I/O operations.

Part Context

This device belongs to the A40MX family, which serves as a high-capacity single-chip ASIC alternative. The family integrates up to 54,000 system gates and features fast wide-decode circuitry. It is designed to replace complex discrete logic solutions while providing deterministic timing and 100% resource utilization capabilities for custom hardware implementations.

Replacement Considerations

Direct substitutes include other members of the A40MX series such as the A40MX02 or A40MX08 if gate density requirements differ. Cross-family migration to Microchip PolarFire or IGloo2 may be necessary for lower power consumption or higher performance needs, though these require significant design re-verification.
