A54SX72A-FGG484A

Overview

The A54SX72A-FGG484A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 6036 configurable logic blocks and 108,000 typical system gates. The device operates within an extended temperature range of -40°C to 125°C and utilizes a 0.22µ CMOS process technology. It supports up to 360 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. The internal performance reaches 250 MHz, facilitated by hardwired clock networks and segmented routing resources.

Feature Summary

• Automotive-grade reliability with extended temperature operation (-40°C to 125°C)
• Nonvolatile antifuse architecture providing deterministic timing and high security
• Hot-swap compliant I/Os allowing safe insertion without system damage
• Integrated boundary scan testing (JTAG) and in-system diagnostic capabilities

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive embedded control logic

Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm if it denotes RoHS-compliant packaging or a specific revision. Confirm that the automotive grade designation aligns with the required operating temperature range for your application. Ensure compatibility with Actel Designer software versions for programming and configuration.

Selection Notes

Select this component when high gate density and automotive environmental resilience are required. The 484-pin FBGA package accommodates the maximum I/O count for the A54SX72A series. Consider the nonvolatile nature of the antifuse technology for designs requiring immediate operation upon power-up without external configuration memory.

Part Context

This part belongs to the SX-A Automotive Family FPGAs, which are designed for harsh environments. The A54SX72A represents the highest capacity device in this specific automotive lineup, offering significant logic resources compared to lower-density variants like the A54SX32A. It shares architectural similarities with commercial SX-A devices but is characterized for extended temperature ranges.

Replacement Considerations

Direct replacements within the same package and pinout may include other speed grades of the A54SX72A series, such as A54SX72A-FFGG484, provided timing requirements are met. Cross-family migration to RT or ProASIC3L requires schematic redesign due to architectural differences.
