A54SX16A-PQ208A

Overview

The A54SX16A-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 24,000 system gates and 1,452 combinatorial cells. The device supports up to 175 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. Operating within a voltage range of 2.25 V to 2.75 V, it delivers internal performance up to 250 MHz. Designed for harsh environments, it operates reliably across an extended temperature range of -40°C to +125°C. The component utilizes a 0.22 µ CMOS process and is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package.

Feature Summary

• Nonvolatile antifuse technology provides inherent security against reverse engineering and design theft.
• Hot-swap compliant I/Os allow safe insertion into active systems without power sequencing requirements.
• Deterministic timing and 100% pin locking enable concurrent PCB development and predictable performance.
• Integrated Silicon Explorer II capability allows unique in-system diagnostic and verification.

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• High-speed controllers and address decoding
• Peripheral bus interfaces

Procurement Notes

Verify the specific ordering suffix 'G' indicates RoHS-compliant packaging if environmental compliance is required. Confirm that the 'A' grade designation corresponds to the specified automotive temperature range of -40°C to 125°C. Ensure compatibility with Actel Designer software for programming and configuration. Check for any product discontinuance notifications or end-of-life status updates from the manufacturer.

Selection Notes

Select this model when an automotive-qualified FPGA with nonvolatile configuration is necessary. The 24,000 gate capacity suits moderate complexity logic designs requiring deterministic timing. Consider the PQFP208 package dimensions for board space constraints. Verify that the 2.5 V core voltage aligns with the system's power supply infrastructure and I/O standards.

Part Context

This component belongs to the SX-A Automotive Family FPGAs, which are designed for high-performance applications in demanding environments. The SX-A series utilizes a sea-of-modules architecture optimized for fast signal propagation and high resource utilization. It serves as a single-chip solution for consolidating logic previously implemented in multiple CPLDs or ASICs.

Replacement Considerations

Consult official Microchip documentation for qualified replacement part numbers. Cross-reference speed grades and package types when selecting alternatives. Verify that any substitute maintains the required automotive temperature specifications and interface compatibility.
