A40MX04-1PL44I

Overview

The A40MX04-1PL44I is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 547 logic elements and approximately 6000 system gates within a 44-pin PLCC package. The device supports mixed-voltage operation with supply ranges of 3V to 3.6V or 4.75V to 5.25V. It operates within an industrial temperature range of -40°C to +85°C and includes up to 57 user-programmable I/O pins.

Feature Summary

• Supports mixed-voltage core and I/O operation for compatibility with both 5.0V and 3.3V systems.
• Provides deterministic, user-controllable timing with 100% resource utilization and pin locking capabilities.
• Features fast wide-decode circuitry and dual-port SRAM access for efficient data handling.

Applications

• Industrial control systems requiring deterministic timing
• Automotive electronics applications
• Mixed-voltage interface bridging

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package type matches the 44-pin PLCC requirement. Check for RoHS compliance status in the latest datasheet revision. Ensure the source document explicitly lists this part number to avoid confusion with similar variants.

Selection Notes

Select this component when a small form factor FPGA with mixed-voltage support is required. Compare against other MX family members if higher gate counts are needed. Verify that the 44-pin PLCC package fits the board layout constraints. Consider the -40°C to +85°C operating range suitability for the target environment.

Part Context

This part belongs to the Microchip Actel MX family of FPGAs, which are known for non-volatile flash-based technology. The A40MX04 variant specifically offers around 6000 system gates, positioning it as a mid-range solution for complex logic replacement tasks compared to smaller devices like the A40MX02.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not found in the provided documentation. Cross-reference with other A40MX04 variants only if package or temperature grades differ.
