A40MX04-1PLG44

Overview

The A40MX04-1PLG44 is a field-programmable gate array 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 44-pin PLCC package. The device supports mixed-voltage operation with core and I/O options at 3.3V or 5.0V, ensuring PCI-compliant interface compatibility. It operates reliably across commercial temperature ranges from 0°C to +70°C. The architecture includes fast wide-decode circuitry and user-programmable I/O pins for flexible digital logic implementation.

Feature Summary

• Supports mixed-voltage operation with 3.3V or 5.0V core and I/O configurations
• Features fast wide-decode circuitry for efficient address decoding
• Provides deterministic, user-controllable timing characteristics
• Enables up to 100% resource utilization and pin locking

Applications

• High-capacity single-chip ASIC replacement designs
• PCI-compliant interface implementations
• Digital logic prototyping and embedded control systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm voltage range and temperature grade. Confirm moisture sensitivity level requirements for surface-mount assembly processes. Ensure design files are compatible with current Actel/Microchip FPGA toolchains. Check for any recent product change notices regarding packaging or assembly sites before finalizing procurement orders.

Selection Notes

Select this component when a moderate gate count with mixed-voltage I/O capability is required in a compact PLCC footprint. Compare against other MX series variants if higher I/O counts or different package types are needed. Verify that the 3.3V or 5.0V supply options align with the target system's power rails. Consider thermal performance within the specified commercial operating temperature range during board layout.

Part Context

This part belongs to the A40MX04 series within the broader MX FPGA family offered by Microchip Technology (formerly Actel). The series is characterized by flash-based non-volatile technology, allowing instant-on functionality without external configuration memory. It serves as a bridge between complex CPLDs and larger FPGAs, offering a balance of density and ease of use for mid-range logic applications.

Replacement Considerations

Direct substitutes include other A40MX04 variants with different packages such as A40MX04-1PLG68 or A40MX04-1PL100A. Cross-family migration to newer Microchip PolarFire or Igloo2 devices may be necessary for long-term supply assurance, requiring significant design re-verification.
