A54SX72A-FG484A

Overview

The A54SX72A-FG484A is an automotive-grade Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 108,000 system gates and up to 360 user-programmable I/O pins. The device operates within an extended temperature range of -40°C to 125°C and supports internal clock frequencies up to 250 MHz. It utilizes a 0.22µ CMOS process technology and includes dedicated flip-flops for sequential logic. The FG484A variant indicates a Fine Pitch Ball Grid Array package with 484 pins.

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 into active systems without power sequencing
• Integrated boundary scan testing (BST) compliant with IEEE Standard 1149.1

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive embedded logic designs requiring nonvolatile configuration

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with Actel Designer software for programming and configuration. Check for any product change notices regarding manufacturing or packaging updates.

Selection Notes

Select this component when designing for automotive environments requiring robust logic density and secure, nonvolatile configuration. Consider the 484-pin FBGA package constraints and the availability of quadrant clocks if complex clock distribution across the die is necessary for the application design.

Part Context

This part belongs to the SX-A Automotive Family FPGAs, which are designed to replace multiple CPLDs in performance-intensive applications. The SX-A series offers a sea-of-modules architecture optimized for fast signal propagation and high resource utilization, specifically tailored for automotive and industrial markets.

Replacement Considerations

Direct replacements within the same package and pinout may include other speed grades of the A54SX72A series, such as A54SX72A-2FG484A, provided timing requirements are met. Cross-family migration to newer Microchip FPGA architectures requires significant redesign.
