A40MX04-2PLG44I

Overview

The A40MX04-2PLG44I is a field-programmable gate array from the Microchip Technology MX series, featuring approximately 6,000 system gates and 547 logic elements. It operates within a supply voltage range of 4.75 V to 5.25 V for 5V core applications or 3.3 V for 3.3V core variants. The device supports mixed-voltage I/O operation with PCI-compliant interfaces. Housed in a 44-pin PLCC package, it is rated for commercial temperature ranges from 0°C to +70°C. This non-volatile FPGA utilizes Flash memory technology for instant-on configuration without external storage.

Feature Summary

• Instant-on capability provided by non-volatile Flash memory architecture eliminating the need for external configuration devices.
• Mixed-voltage I/O support allowing compatibility with both 3.3V and 5.0V systems through configurable core voltages.
• High-density programmable logic structure offering up to 100% resource utilization and pin locking capabilities.

Applications

• Replacement for complex programmable logic devices (CPLDs) in high-capacity single-chip ASIC alternative designs.
• Industrial control systems requiring deterministic timing and mixed-voltage interface compatibility.
• Automotive electronics utilizing commercial-grade plastic packages for logic implementation.

Procurement Notes

Verify the specific suffix designation to confirm the operating temperature grade and core voltage selection. The 'I' suffix typically indicates industrial temperature range, whereas this model's base specifications often cite commercial ranges; cross-reference the official datasheet to ensure the thermal rating matches the application requirements. Confirm moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when a non-volatile FPGA with instant-on functionality is required for logic densities around 6,000 gates. Ensure the design accommodates the 44-pin PLCC footprint and validates power supply stability within the specified 4.75V to 5.25V window for 5V core operation. Consider the mixed-voltage I/O flexibility if interfacing with legacy 5V peripherals.

Part Context

This part belongs to the A40MX04 family within the broader MX FPGA line, which serves as a high-capacity alternative to traditional ASICs. The family spans from 3,000 to 54,000 system gates, providing scalable logic resources. The A40MX04 variant specifically targets applications needing moderate density with the reliability of Flash-based reprogrammability.

Replacement Considerations

Direct substitutes include other members of the A40MX04 family such as the A40MX04-2PLG44 or A40MX04-PLG44I, depending on the required temperature grade. Verify pin-to-pin compatibility and logical equivalence before substitution.
