A54SX32A-TQG144A

Overview

The A54SX32A-TQG144A 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 2,880 configurable logic blocks and 48,000 system gates. The device supports up to 249 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. Operating within an extended temperature range of -40°C to 125°C, it utilizes a 0.22µ CMOS process technology. The TQG144A suffix indicates a Thin Quad Flat Pack package with 144 pins.

Feature Summary

• Nonvolatile antifuse-based architecture providing deterministic performance and high 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 multiple voltage standards including 3.3V PCI, LVTTL, and LVCMOS2

Applications

• In-cabin telematics systems for automotive environments
• Automobile interconnect applications requiring extended temperature stability
• Complex logic integration replacing multiple CPLDs in performance-intensive designs

Procurement Notes

Verify the specific speed grade and packaging configuration required for your design constraints. Confirm that the automotive temperature grade (-40°C to 125°C) aligns with your operational environment specifications. Ensure compatibility with Actel Designer software for programming and configuration. Check for any recent product change notifications regarding manufacturing or sourcing updates.

Selection Notes

Select this component when designing for automotive applications requiring nonvolatile logic and high reliability. Consider the 48,000 system gate capacity for moderate complexity designs. Evaluate the 144-pin TQFP package dimensions against your PCB layout constraints. Verify that the available I/O count meets your interface requirements for sensors, displays, or communication buses.

Part Context

This part belongs to the SX-A Automotive Family FPGAs, which are designed specifically for harsh automotive environments. The family includes variants like A54SX08A, A54SX16A, and A54SX72A, offering different gate counts and pin configurations. The SX-A series is characterized by its metal-to-metal antifuse technology, ensuring permanent configuration without the need for external memory.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as A54SX32A-1TQG144A or A54SX32A-2TQG144A, provided timing requirements are met. Cross-family migration to newer Microchip FPGA architectures requires significant redesign due to architectural differences.
