A40MX04-3VQG80

Overview

The A40MX04-3VQG80 is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 547 configurable logic blocks (CLBs) and approximately 6,000 system gates. The device supports mixed-voltage operation with supply voltages of 3.3V or 5.0V for both core and I/Os, ensuring PCI-compliant interface compatibility. It is housed in an 80-pin VQFP package and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports mixed-voltage operation for flexible 3.3V or 5.0V core and I/O configurations
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities
• Integrates fast wide-decode circuitry and configurable dual-port SRAM for efficient data handling

Applications

• High-capacity single-chip ASIC replacement designs
• PCI-compliant interface implementations requiring mixed-voltage support
• Digital signal processing applications utilizing onboard SRAM

Procurement Notes

Verify the specific speed grade suffix '3' against the official datasheet to confirm timing performance requirements. Confirm that the VQFP-80 package dimensions align with the target PCB footprint. Ensure environmental compliance documentation matches project specifications.

Selection Notes

Select this component when a dense logic solution with mixed-voltage I/O flexibility is required. Compare CLB counts and SRAM capacity against similar MX series devices. Validate that the 0°C to 70°C operating range meets the system's thermal constraints.

Part Context

This part belongs to the A40MX04 series within the broader 40MX/42MX FPGA family. These devices are characterized by their ability to replace complex ASICs with reconfigurable logic. The family offers scalable gate counts and integrated memory options for various embedded control applications.

Replacement Considerations

Cross-reference with other A40MX04 variants such as A40MX04-VQG80 or A40MX04-PLG68 if package changes are acceptable. Verify pin-to-pin compatibility before substituting with different speed grades or package types.
