A40MX04-3VQ80

Overview

The A40MX04-3VQ80 is a field-programmable gate array from the Microchip Technology MX FPGA family, housed in an 80-pin VQFP package. It provides approximately 6,000 system gates and 547 configurable logic blocks (CLBs). The device supports mixed-voltage operation with core and I/O voltages of either 3.3V or 5.0V, ensuring PCI-compliant I/O compatibility. It features up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications. The component operates within a commercial temperature range of 0°C to +70°C and includes fast wide-decode circuitry with up to 69 user-programmable I/O pins.

Feature Summary

• Supports mixed-voltage operation for both core and I/O domains at 3.3V or 5.0V levels
• Integrates configurable dual-port SRAM for embedded data storage functions
• Provides deterministic timing control with user-controllable resource utilization
• Features fast wide-decode circuitry for efficient address decoding

Applications

• Single-chip ASIC replacement designs
• Mixed-voltage interface bridging between different logic families
• Embedded memory implementations using onboard SRAM

Procurement Notes

Verify the specific speed grade suffix '3' against the official datasheet to confirm maximum clock frequency and propagation delay specifications. Ensure the VQFP-80 package dimensions match the target PCB footprint requirements. Confirm that the commercial temperature rating aligns with the operational environment constraints before finalizing procurement orders.

Selection Notes

Select this model when a design requires approximately 6,000 system gates with integrated SRAM capabilities. The VQFP-80 package offers a balance of pin count and board space efficiency. Verify that the required I/O voltage standards are compatible with the 3.3V or 5.0V mixed-voltage support provided by the MX FPGA architecture.

Part Context

This component belongs to the Actel MX FPGA family, originally developed by Actel and acquired by Microsemi, now part of Microchip Technology. The series is characterized by its flash-based non-volatile technology, which eliminates the need for external configuration memory. This specific variant represents a mid-range density option within the broader MX portfolio.

Replacement Considerations

Direct replacements include other variants within the A40MX04 series such as the A40MX04-1PLG44 or A40MX04-VQG80, depending on package and speed grade requirements. Cross-family migration to PolarFire or IGloo2 devices may be necessary for updated feature sets, though pinouts and architectures differ significantly.
