A40MX04-PL44

Overview

The A40MX04-PL44 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features approximately 6,000 system gates and 547 Logic Elements (LEs). The device supports dual voltage operation at 3.3 V and 5 V, with supply voltage ranges of 3.0 V to 3.6 V and 4.75 V to 5.25 V respectively. It offers 34 I/O pins and utilizes a PLCC-44 surface-mount package. The commercial temperature grade operates between 0°C and +70°C. This non-volatile FPGA is designed for applications requiring low power consumption and high reliability without embedded memory blocks.

Feature Summary

• Non-volatile flash-based architecture retains configuration data without external memory.
• Supports both 3.3V and 5V logic levels for flexible interface compatibility.
• Low power consumption suitable for battery-operated or portable systems.
• High reliability design resistant to single-event upsets in radiation environments.

Applications

• Industrial control systems requiring deterministic logic performance.
• Automotive electronics interfaces and sensor signal processing.
• Telecommunications equipment for protocol conversion and buffering.
• Consumer electronics where space constraints limit component count.

Procurement Notes

Verify the specific suffix requirements for temperature range and package type when ordering. Confirm RoHS compliance status with the manufacturer as regulations evolve. Check for active production status and lead times directly with authorized distributors. Ensure ESD handling procedures are followed during storage and assembly due to moisture sensitivity classification.

Selection Notes

Select this model for designs needing moderate logic density with non-volatile configuration. Compare against the A40MX02 for lower gate counts or A42MX series for enhanced features. Consider the PLG44 variant if industrial temperature range (-40°C to +85°C) is required instead of commercial grade. Evaluate pin count limitations against system I/O requirements before finalizing the choice.

Part Context

This component belongs to the Actel MX family, now part of Microchip Technology's portfolio. The MX series is known for its flash-based FPGA technology, which eliminates the need for external configuration PROMs. It serves as a cost-effective solution for replacing complex discrete logic or ASICs in mid-volume production runs.

FAQ

Does the A40MX04-PL44 require an external configuration memory?

No, it uses non-volatile flash technology, allowing it to boot directly from internal configuration memory without external PROMs.

What is the maximum operating frequency?

The datasheet specifies a maximum clock frequency of 80 MHz for this device.

Is this device suitable for automotive applications?

Yes, the MX family is qualified for automotive applications, though the specific -PL44 suffix indicates commercial temperature range; verify if industrial grade is needed for harsh environments.
