A54SX72A-FG484M

Overview

The A54SX72A-FG484M is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 484-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 360 user-programmable I/O pins and includes three global routed clocks plus four quadrant clocks. It operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology with mixed-voltage support for 2.5 V, 3.3 V, and 5 V I/Os. The military temperature grade (-55°C to +125°C) ensures reliability in harsh environments.

Feature Summary

• Supports hot-swap operations and power-up/down without supply voltage sequencing requirements
• Provides deterministic timing through metal-to-metal programmable antifuse interconnect elements
• Includes boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG)
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• High-performance digital signal processing systems
• Industrial control applications requiring extended temperature ranges
• Automotive electronics utilizing automotive-grade specifications
• Military and aerospace defense systems

Procurement Notes

Verify the specific ordering suffix 'M' against official documentation to confirm it denotes the military temperature grade (-55°C to +125°C). Confirm that the component is available in lead-free packaging if required by project specifications. Ensure compatibility with existing design tools for the SX-A family before procurement.

Selection Notes

Select this model when high gate density and robust environmental tolerance are necessary. The 484-pin FBGA package accommodates extensive I/O requirements. Consider the speed grade '-F' or standard variants based on timing constraints. Verify that the mixed-voltage I/O capabilities align with the target system's interface standards.

Part Context

This component belongs to the SX-A family of FPGAs, which utilizes nonvolatile antifuse technology. The family offers various capacity options ranging from 12,000 to 108,000 system gates. The A54SX72A represents the highest capacity device in this specific series, providing maximum logic resources for complex designs.

Replacement Considerations

Check for updated revisions within the A54SX72A series. Consult official substitution guides for pin-compatible alternatives if the exact suffix is unavailable. Ensure any replacement maintains the same package type and temperature rating.
