A40MX04-PL44I

Overview

The A40MX04-PL44I is a field-programmable gate array from the Microchip MX series, featuring 547 logic elements and 6000 system gates. It operates within a supply voltage range of 3V to 3.6V or 4.75V to 5.25V. The device provides 41 I/O pins in a 44-pin PLCC package with J-leads. It supports a maximum clock frequency of 80 MHz with a CLB combinational delay of 2.7 ns. The component functions across an industrial temperature range of -40°C to +85°C and holds a Moisture Sensitivity Level (MSL) rating of 3.

Feature Summary

• Non-volatile flash-based FPGA architecture enabling instant-on functionality without external configuration memory.
• Supports both 3.3V and 5V power supply domains for flexible interface compatibility.
• Integrated high-speed serial programming capability for simplified design workflows.

Applications

• Industrial control systems requiring robust programmable logic.
• Automotive electronics operating under extended temperature conditions.
• Communication protocol conversion and signal processing interfaces.

Procurement Notes

Verify the specific suffix 'PL44I' against official Microchip documentation to confirm the package type and temperature grade. Ensure compliance with RoHS directives and check for any recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement specifications.

Selection Notes

Select this model when a compact 44-pin form factor is required alongside 547 logic elements. Confirm that the 80 MHz performance meets timing requirements. Verify that the -40°C to +85°C industrial range aligns with the target environment, distinguishing it from commercial or extended military variants.

Part Context

This component belongs to the Actel MX family, now manufactured by Microchip Technology. It represents a mid-range density solution within the portfolio, bridging basic discrete logic and complex high-density FPGAs. The part retains the legacy Actel branding often associated with its flash-based technology lineage.

Replacement Considerations

Direct substitutes include other members of the A40MX04 series with different packages, such as A40MX04-PLG44I or A40MX04-VQG80, provided pin counts and thermal ratings are compatible. Cross-family migration to A54SX models requires significant schematic and code adjustments due to architectural differences.
