A40MX04-2PL68

Overview

The A40MX04-2PL68 is a Field Programmable Gate Array (FPGA) from the Microchip Technology MX series. It features approximately 6,000 system gates and 547 Logic Elements. The device supports mixed-voltage operation with supply voltages of 3.3 V or 5 V. It provides up to 57 user-programmable I/O pins and utilizes a PLCC-68 surface-mount package. The component operates within a temperature range of -40°C to +85°C for industrial applications.

Feature Summary

• Functions as a single-chip ASIC alternative with high capacity logic resources.
• Supports mixed-voltage core and I/O operations compatible with 3.3V and 5V standards.
• Includes fast wide-decode circuitry for efficient logic implementation.

Applications

• Industrial control systems requiring robust programmable logic.
• Automotive electronics operating in extended temperature environments.
• Military and aerospace applications utilizing HiRel certified variants.

Procurement Notes

Verify the exact suffix against official Microchip documentation, as standard listings often use 'PLG' for plastic packages. Confirm RoHS compliance status and humidity sensitivity level prior to ordering. Ensure the specific speed grade matches design timing requirements. Check for active manufacturing status to avoid obsolescence risks during production.

Selection Notes

Select this model when a moderate gate count with mixed-voltage I/O capability is required. Compare pin counts against the target PCB footprint, specifically the PLCC-68 dimensions. Evaluate thermal performance within the specified industrial temperature range. Consider the availability of ECAD models for schematic and layout integration.

Part Context

This component belongs to the Actel MX family, now under Microchip Technology. The A40MX04 variant offers a balance of density and power efficiency compared to larger devices like the A42MX series. It serves as a direct replacement for legacy CPLDs in complex digital logic designs.

Replacement Considerations

Direct substitutes include other MX series parts such as A40MX02 or A40MX08 if gate counts differ. Verify pin compatibility for PLCC-68 footprints. Cross-reference with A42MX equivalents for enhanced features while maintaining interface consistency.
