A54SX72A-FG256A

Overview

The A54SX72A-FG256A 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 108,000 system gates and 6,036 logic modules. The device operates within a temperature range of -40°C to +125°C and utilizes a 0.22µ CMOS process. It supports up to 360 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. The FPGA offers internal performance up to 250 MHz and supports hot-swap compliant I/Os. It is housed in a 256-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Automotive-grade reliability with extended temperature support (-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 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 component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status as packaging suffixes may vary. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly. Check for any specific automotive qualification certifications required by your supply chain standards.

Selection Notes

Select this model when designing for harsh automotive environments requiring wide temperature tolerance. The 108,000 gate capacity suits complex logic implementations replacing multiple CPLDs. Consider the FBGA-256 package constraints for PCB layout. Verify that the 250 MHz internal clock speed meets your timing closure requirements for the target application.

Part Context

This part belongs to the Actel SX-A Automotive Family FPGAs series. It represents the highest capacity device in the standard SX-A lineup, offering 108,000 system gates. The 'A' suffix denotes the automotive temperature grade, while 'FG256' specifies the 256-pin FBGA package. It is designed to provide a single-chip solution for robust, secure programmable logic.

Replacement Considerations

Direct replacements within the same package and pinout are limited due to the specific automotive grade and antifuse technology. Evaluate other SX-A family members like A54SX32A if lower capacity suffices, noting pin count differences. Cross-family migration to SmartFusion or IGLOO requires significant architectural redesign.
