A40MX04-VQG80M

Overview

The A40MX04-VQG80M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features approximately 6,000 system gates and 547 Logic Elements (LEs). The device supports mixed-voltage operation with core and I/O options for 3.3V or 5.0V supplies, ensuring PCI compliance. It utilizes SRAM-based technology, allowing for 100% resource utilization and pin locking. The component is housed in an 80-pin VQFP package with dimensions of 14x14 mm, suitable for surface-mount applications.

Feature Summary

• Supports mixed-voltage operation for both core and I/O domains at 3.3V or 5.0V.
• Enables deterministic timing through user-controllable logic and 100% pin locking capabilities.
• Integrates fast wide-decode circuitry and configurable dual-port SRAM resources.

Applications

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

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a military-grade temperature range or specific qualification standard distinct from commercial variants. Ensure the ordering part number matches the exact package and speed grade required for the design. Cross-reference the datasheet revision date to confirm current manufacturing status and any recent packaging changes.

Selection Notes

Select this model when the design requires approximately 6,000 system gates with mixed-voltage I/O flexibility. The VQFP-80 package is appropriate for space-constrained surface-mount layouts. Consider the SRAM-based nature of the device for reprogrammability needs. Verify that the target application environment aligns with the specified operating temperature range associated with the 'M' suffix variant.

Part Context

This component belongs to the A40MX/42MX FPGA family, which offers scalable capacities ranging from 3,000 to 54,000 system gates. The family is characterized by its ability to replace complex ASICs with programmable logic solutions. The MX series provides high performance with low power consumption relative to comparable SRAM FPGAs, supporting various industrial and commercial applications.

Replacement Considerations

Direct substitutes within the same gate count include other packages in the A40MX04 series such as PLG68 or CQG100 variants, provided pin compatibility is addressed via retiming or redesign. For higher capacity needs, consider the A40MX08 or A40MX16 models. Verify that any replacement maintains the required voltage levels and package footprint constraints.
