A40MX04-3PL44

Overview

The A40MX04-3PL44 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a high-capacity single-chip ASIC alternative. It features 547 Configurable Logic Blocks (CLBs) and approximately 6,000 system gates. The device supports mixed-voltage operation with supply voltage ranges of 3V to 3.6V for the core and 4.75V to 5.25V for I/Os. It utilizes a 44-pin Plastic Leaded Crystal Carrier (PLCC) package with J-leads. The component operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports mixed-voltage operation allowing compatibility with both 5.0V and 3.3V core and I/O configurations.
• Provides deterministic, user-controllable timing characteristics suitable for precise logic design.
• Enables 100% resource utilization and complete pin locking capabilities during configuration.

Applications

• High-capacity single-chip ASIC replacement
• Mixed-voltage interface circuits
• Commercial industrial control systems

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure the ordering code matches the required PLCC-44 form factor. Confirm that the selected variant aligns with the intended commercial operating temperature range requirements.

Selection Notes

Select this model when a dense logic solution in a low-pin-count plastic package is required. Compare CLB counts against simpler CPLDs if higher complexity is needed. Verify that the 44-pin footprint fits the target PCB layout constraints without requiring complex routing adjustments.

Part Context

This part belongs to the Microchip MX family of SRAM-based FPGAs. These devices are engineered to replace complex discrete logic or standard ASICs. The family offers flexibility through reprogrammability while maintaining performance levels comparable to dedicated hardware solutions.

Replacement Considerations

Direct substitutes include other MX series variants such as the A40MX02 or A42MX09, provided they meet the gate count and I/O requirements. Cross-referencing with Actel legacy part numbers may be necessary for older designs migrating to Microchip components.
