A54SX16A-FGG144A

Overview

The A54SX16A-FGG144A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microsemi Corporation. It features a sea-of-modules architecture with 24,000 system gates and 1,452 logic modules. The device operates at internal clock frequencies up to 250 MHz and supports up to 180 user-programmable I/O pins. It utilizes a 0.22µ CMOS process technology and includes nonvolatile antifuse programming for secure design implementation. The component is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes unique in-system diagnostic capabilities via Silicon Explorer II for real-time internal node observation.
• Features Actel FuseLock security technology to prevent reverse engineering and unauthorized access to design data.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and packaging specifications. Confirm RoHS compliance status if environmental regulations apply to the target assembly. Ensure the supplier provides documentation verifying the part originates from authorized manufacturing channels to guarantee authenticity and traceability.

Selection Notes

Select this device when designing for automotive environments requiring operation across extended temperature ranges. Consider the 250 MHz internal performance and 1452 logic modules for complex state machine implementations. Evaluate the FBGA-144 package constraints against PCB layout requirements and thermal dissipation needs for the final enclosure design.

Part Context

This component belongs to the SX-A Automotive Family of FPGAs, designed specifically for harsh environment applications. It shares architectural similarities with commercial and industrial grades but is characterized for automotive reliability standards. The SX-A line offers scalable gate counts ranging from 8,000 to 108,000 system gates across different device variants.

Replacement Considerations

Compatible substitutes within the same family include other A54SX16A variants with different package types such as TQFP or PQFP, provided pin compatibility is verified. Devices like A54SX16A-TQG144 offer similar logical capacity but differ in physical footprint and pinout configuration.
