A40MX04-2VQ80

Overview

The A40MX04-2VQ80 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 configurable logic blocks (CLBs). The device supports mixed-voltage operation with supply voltages of 3.3V or 5.0V for both core and I/Os, ensuring PCI compliance. It utilizes an 80-pin VQFP package and offers up to 202 user-programmable I/O pins. Key performance metrics include a maximum clock frequency of 250 MHz and a clock-to-out delay of 5.6 ns.

Feature Summary

• Supports mixed-voltage operation with 5.0V or 3.3V supplies for core and I/Os, maintaining PCI-compliant I/O standards.
• Features fast wide-decode circuitry and dual-port SRAM access times of 5 ns, enabling efficient FIFO implementations at 100 MHz.
• Provides deterministic, user-controllable timing with 100% resource utilization and pin locking capabilities.

Applications

• High-speed data processing requiring deterministic timing control
• PCI-compliant interface designs
• ASIC prototyping and low-volume production

Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm voltage ranges and temperature grades. Ensure compatibility with existing PCB footprints for the VQFP-80 package. Check for any recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when a dense FPGA solution with mixed-voltage I/O support is required. Compare against other MX family members based on I/O count and package size constraints. Verify that the 250 MHz performance meets the target application's speed requirements without necessitating higher-tier devices.

Part Context

This part belongs to the A40MX04 series within the broader MX FPGA family. It serves as a bridge between standard CPLDs and larger FPGAs, offering significant logic density in a compact form factor. The series is known for its non-volatile flash technology, allowing instant-on functionality without external configuration memory.

Replacement Considerations

Direct replacements may include other variants within the A40MX04 family with different packages, such as PLCC or PQFP options. Cross-family migration to newer Actel or Microchip FPGA lines requires careful re-evaluation of pinouts and logic resources.
