A40MX02-1PQ100M

Overview

The A40MX02-1PQ100M is a field-programmable gate array (FPGA) from the Microchip MX family, designed for low-power applications. It features 295 logic elements and approximately 3,000 system gates. The device supports dual voltage operation with a minimum supply of 4.75 V and a maximum of 5.25 V, alongside a 3.3 V option. It provides 57 I/O pins and operates within a commercial temperature range of 0°C to +70°C. The component is housed in a 100-pin PQFP package.

Feature Summary

• Utilizes flash-based non-volatile technology for instant-on functionality without external configuration memory.
• Supports multiple voltage domains including 5V and 3.3V for flexible interface compatibility.
• Integrates code protection features to secure intellectual property within the design.

Applications

• Low-power embedded control systems
• Industrial communication interfaces
• Consumer electronics logic replacement

Procurement Notes

Verify the specific suffix 'M' against the official Microchip datasheet to confirm if it denotes a moisture-resistant or lead-free variant, as standard part numbers may differ. Confirm the package type matches the 100-pin PQFP specification. Ensure the speed grade '1' aligns with the required timing constraints for the target application before procurement.

Selection Notes

Select this model when a small-scale FPGA with immediate power-up capability is required. Compare the 295 logic element count against design complexity to ensure sufficient resources. Verify that the 57 available I/O pins meet the interface requirements. Consider the commercial temperature range limits if the operating environment exceeds 70°C.

Part Context

This component belongs to the A40MX series, which represents an earlier generation of flash FPGAs acquired by Microchip through the Actel acquisition. It serves as a legacy alternative to newer PolarFire or IGLOO families for cost-sensitive or space-constrained designs requiring simple programmable logic.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary architecture. Potential alternatives include the A40MX02 variants with different packages or speed grades. Upgrading to the A42MX02 series may offer increased capacity but requires schematic review. Consult Microchip for current obsolescence status and recommended migration paths.
