A40MX04-3VQ80I

Overview

The A40MX04-3VQ80I is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip Technology MX family. It provides 5,470 system gates organized into 295 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with 5.0V or 3.3V core and I/O supplies, featuring PCI-compliant inputs. Key electrical parameters include a maximum clock frequency of 48.24 MHz and a CLB combinational delay of 3.72 ns. It operates within a commercial temperature range of -40°C to +85°C and utilizes a 64-pin VQFP package.

Feature Summary

• Supports mixed-voltage operation for flexible 5.0V or 3.3V core and I/O configurations
• Features fast wide-decode circuitry for efficient logic implementation
• Includes up to 2.5 kbits of configurable dual-port SRAM for data storage

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-voltage interface bridging between different logic families
• Digital signal processing applications requiring deterministic timing

Procurement Notes

Verify the specific suffix '3VQ80I' against the official Microchip datasheet to confirm the speed grade, package type, and industrial temperature rating. Ensure the ordering part number matches the required voltage specifications and pinout configuration before procurement.

Selection Notes

Select this component when a design requires approximately 5,470 system gates with mixed-voltage I/O capabilities. Consider the 48.24 MHz performance limit and 3.72 ns CLB delay for timing closure. Verify that the 64-pin VQFP package fits the board layout constraints compared to other available packages in the A40MX04 series.

Part Context

This device belongs to the A40MX04 series within the broader MX FPGA family. It shares architectural similarities with other variants like the A40MX04-CQ100I but differs in package density and pin count. The series is characterized by its non-volatile flash technology and compatibility with standard development tools.

Replacement Considerations

Direct replacements within the same family include the A40MX04-VQ80I or A40MX04-3VQ80M, depending on the required temperature grade and speed bin. Cross-family migration may require significant redesign due to differences in architecture and resource availability.
