A40MX04-VQ80M

Overview

The A40MX04-VQ80M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 547 Configurable Logic Blocks (CLBs) and approximately 6,000 system gates. The device supports mixed-voltage operation with core and I/O options for 3.3V or 5.0V supplies, ensuring PCI compliance. It includes up to 2.5 kbits of configurable dual-port SRAM and wide-decode circuitry. The VQ80M suffix indicates a 80-pin Very Thin Quad Flat Package (VQFP). Key performance metrics include a maximum clock frequency of 250 MHz and a clock-to-output delay of 5.6 ns.

Feature Summary

• Supports mixed-voltage operation for both core logic and I/O pins, compatible with 3.3V and 5.0V standards.
• Integrates configurable dual-port SRAM for flexible memory applications and FIFO implementations.
• Features wide-decode circuitry and deterministic, user-controllable timing for precise design implementation.
• Allows 100% resource utilization and complete pin locking for robust hardware definition.

Applications

• High-speed serial communication interfaces requiring deterministic timing.
• Industrial control systems utilizing mixed-voltage signal processing.
• Automotive electronics applications demanding reliable programmable logic.
• Military and aerospace systems requiring radiation-tolerant or high-reliability components.

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm military-grade temperature ratings and qualification standards. Ensure compatibility with existing PCB footprints for the 80-pin VQFP package. Cross-reference the latest datasheet revision to confirm pinout consistency and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this model when designing systems requiring high gate density within a compact footprint. It is suitable for replacing complex discrete logic or standard ASICs in prototyping phases. Consider the 250 MHz performance limit for high-speed data paths. Evaluate the available SRAM resources against algorithm complexity requirements to ensure sufficient on-chip memory capacity.

Part Context

This component belongs to the A40MX series, which bridges the gap between low-density CPLDs and high-end FPGAs. The MX family is known for its non-volatile configuration technology, allowing instant-on functionality without external configuration memory. This specific variant targets applications needing moderate logic capacity with high reliability and mixed-signal capabilities.

Replacement Considerations

Direct replacements may include other variants within the A40MX family with different package types, such as PLCC or BGA versions, provided pin counts match. Verify that any substitute maintains the same voltage levels and timing specifications. Consult Microchip's official obsolescence notices for potential lifecycle changes or recommended next-generation alternatives.
