A54SX32A-PQ208A

Overview

The A54SX32A-PQ208A 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 174 user-programmable I/Os in a 208-pin Plastic Quad Flat Pack (PQFP). The device operates within a supply voltage range of 2.25 V to 2.75 V and supports internal clock frequencies up to 250 MHz. Designed for harsh environments, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Ensure compatibility with Actel Designer software for configuration. Check for RoHS compliance status if required by assembly specifications. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component for designs requiring high-speed logic processing in automotive environments. Consider the 208-pin PQFP package for surface-mount assembly needs. Evaluate pin count requirements against the 174 available I/Os. Ensure design tools support the SX-A architecture for optimal resource utilization.

Part Context

This part belongs to the SX-A Automotive Family, which includes variants like A54SX08A, A54SX16A, and A54SX72A. These devices share a common architecture but differ in gate capacity and I/O counts. The SX-A series is designed to replace multiple CPLDs or gate arrays in complex digital designs.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series. Cross-family migration to newer Microchip FPGA families requires schematic and layout redesign due to architectural differences.
