A40MX04-2PLG68I

Overview

The A40MX04-2PLG68I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features approximately 6,000 system gates and 547 Logic Elements within a PLCC-68 package. The device supports mixed-voltage operation with supply ranges of 3.3V or 5.0V for both core and I/Os. It operates reliably across an industrial temperature range of -40°C to +85°C. Key specifications include 57 user-programmable I/O pins and compliance with RoHS standards.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with 3.3V or 5.0V systems
• Includes configurable dual-port SRAM for efficient data buffering and FIFO applications
• Features fast wide-decode circuitry for rapid address decoding and control logic

Applications

• Industrial automation control systems
• Automotive embedded controllers
• Military communication equipment interfaces

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the PLCC-68 package type matches the target PCB footprint. Check moisture sensitivity level requirements for reflow soldering processes. Ensure the design tool version supports the MX FPGA architecture for proper configuration bitstream generation.

Selection Notes

Select this component when a moderate gate count with mixed-voltage compatibility is required in a compact PLCC package. Compare against the A40MX02 series if lower resource utilization suffices. Consider the A40MX04-1PLG68 variant if commercial temperature range (0°C to 70°C) is adequate for the application environment.

Part Context

This part belongs to the Microsemi/Actel MX FPGA family, known for non-volatile flash-based technology that eliminates the need for external configuration memory. The A40MX04 model represents a mid-range density option within this lineage, offering a balance between logic capacity and pin count for general-purpose programmable logic tasks.

Replacement Considerations

Direct functional substitutes within the same package and speed grade are limited due to proprietary architecture. Verify cross-compatibility with other A40MX04 variants differing only in temperature grade or speed bin before substitution.
