A54SX32A-PQG208A

Overview

The A54SX32A-PQG208A 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 48,000 system gates and supports up to 174 user-programmable I/Os in its 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates within a supply voltage range of 2.25 V to 2.75 V, centered at 2.5 V, and is qualified for extended temperature ranges from -40°C to +125°C. Internal performance reaches 250 MHz, utilizing 0.22 µ CMOS process technology.

Feature Summary

• Nonvolatile antifuse-based architecture providing deterministic timing and inherent security against reverse engineering.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 for diagnostic and verification capabilities.
• Configurable I/O modules supporting mixed-voltage operation including 3.3V PCI, LVTTL, and 2.5V LVCMOS2 standards.

Applications

• In-cabin telematics systems requiring robust automotive environmental qualification.
• Automobile interconnect applications demanding high-speed data processing.
• Complex logic integration replacing multiple CPLDs or gate arrays in space-constrained designs.

Procurement Notes

Verify the specific ordering suffix and package type when sourcing, as availability varies by manufacturer distribution channels. Confirm RoHS compliance status and lead times directly with authorized suppliers, as automotive-grade components may have distinct supply chain constraints compared to commercial variants.

Selection Notes

Select this component for designs requiring nonvolatile configuration and high reliability in harsh environments. Ensure the design accommodates the 2.5 V core voltage and validates I/O levels against the supported 3.3V and 2.5V standards. Consider the 208-pin PQFP footprint for PCB layout compatibility and thermal management requirements.

Part Context

This part belongs to the Actel SX-A Automotive Family, which extends the standard SX-A FPGA line with extended temperature grading. It shares architectural similarities with other SX-A devices like the A54SX32A-TQG100A but differs in package density and I/O count. The family utilizes antifuse technology for permanent programming, distinguishing it from SRAM-based FPGAs.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific antifuse architecture and automotive grading. Evaluate alternative SX-A family members with compatible pin counts or migrate to modern Microchip PolarFire or IGLOO2 families for updated feature sets, ensuring software toolchain compatibility.
