A40MX04-2PLG84I

Overview

The A40MX04-2PLG84I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, featuring 6,000 system gates and 547 logic elements. It operates within a supply voltage range of 4.5 V to 5.5 V and supports dual voltage operation at 3.3 V and 5 V. The device provides 69 I/O pins and is housed in an 84-pin PLCC package. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides single-chip ASIC alternative capabilities for automotive applications with up to 100% resource utilization and pin fixing.
• Features fast wide-decode circuitry and a synthesis-friendly architecture that supports standard ASIC design methodologies.
• Includes unique in-system diagnostic capability via Silicon Explorer II for verification and testing.

Applications

• Automotive electronic systems requiring high reliability and deterministic timing.
• Industrial control applications needing robust programmable logic solutions.
• General-purpose digital logic replacement for complex discrete circuits.

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 84-pin PLCC configuration. Confirm moisture sensitivity level handling requirements during assembly to prevent damage. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when 6,000 system gates and 69 I/Os are required for industrial or automotive environments. Compare against other MX series variants if different pin counts or commercial temperature ranges suffice. Consider the PLCC package constraints regarding board space and thermal management. Verify that the 5V supply requirement aligns with the target system power rails.

Part Context

This component belongs to the A40MX04 series within the broader Microchip MX FPGA portfolio. It shares architectural similarities with other devices in the family, such as the A40MX02 and A42MX24, but offers a specific balance of gate count and I/O density. The series is designed to replace complex programmable logic devices in legacy designs.

Replacement Considerations

Direct substitutes include other A40MX04 variants with different packages or speed grades, such as A40MX04-3PLG84I or A40MX04-VQG80I, provided pinout compatibility is verified. Check datasheets for any differences in I/O drive strength or configuration options between speed grades.
