A40MX04-1VQ80

Overview

The A40MX04-1VQ80 is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features approximately 6,000 system gates and 547 logic elements within a VQFP-80 package. The device supports mixed-voltage operation with core and I/O options for 3.3V or 5.0V supplies, ensuring PCI compliance. Key specifications include up to 202 user-programmable I/O pins, a maximum clock frequency of 80 MHz, and a CLB delay of 2.7 ns. It operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports mixed-voltage operation with 3.3V or 5.0V core and I/O configurations.
• Features fast wide-decode circuitry and deterministic, user-controllable timing.
• Allows 100% resource utilization and 100% pin locking capabilities.

Applications

• High-capacity single-chip ASIC replacement designs
• PCI-compliant interface implementations
• Complex digital logic prototyping

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage and temperature ratings. Confirm package type matches the required PCB footprint. Check for RoHS compliance status in current documentation. Ensure availability through authorized Microchip distributors. Validate lead times directly with suppliers.

Selection Notes

Select this model for applications requiring moderate logic density with mixed-voltage support. Compare against other MX series variants based on I/O count and package constraints. Consider the 80 MHz performance limit for timing-critical designs. Verify thermal requirements for the VQFP-80 package in the target environment.

Part Context

This component belongs to the Microchip MX FPGA family, which serves as a bridge between standard PLDs and complex FPGAs. The A40MX04 variant specifically targets designs needing around 6,000 system gates. It is part of the broader Actel heritage acquired by Microchip, known for non-volatile flash-based FPGA technology.

Replacement Considerations

Direct substitutes may include other A40MX04 variants with different packages or speed grades. Cross-reference pinouts when considering package changes. Verify electrical compatibility if substituting with higher-speed versions like the -2 suffix.
