A54SX72A-PQG208I

Overview

The A54SX72A-PQG208I is a high-performance Field Programmable Gate Array (FPGA) from the Actel SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 360 user-programmable I/O pins and includes three global clocks plus four quadrant clocks. Operating at industrial temperatures (-40°C to +85°C), it utilizes 0.22 μm / 0.25 μm CMOS antifuse technology with mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V systems.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing safe insertion into active systems without power sequencing requirements.
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Integrated security features including FuseLock technology to prevent reverse engineering and unauthorized design access.

Applications

• High-speed data path logic and fast counters requiring deterministic timing.
• Complex state machine implementations in industrial control systems.
• Systems requiring hot-swappable interface capabilities with mixed voltage standards.
• Secure embedded designs needing protection against intellectual property theft.

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm the specific ordering suffix matches the required temperature grade and package type. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure proper handling procedures are followed due to moisture sensitivity level 3 classification.

Selection Notes

Select this model when 108,000 system gates and 360 I/Os are required within a PQFP-208 footprint. Consider the -1 speed grade if approximately 15% faster performance than standard is needed. Evaluate the quadrant clock resources available only in the A54SX72A variant for complex clock distribution needs across the die.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microchip Technology. The SX-A series is characterized by its antifuse-based nonvolatile architecture, offering high reliability and security compared to volatile SRAM-based FPGAs. It serves as a bridge between CPLDs and larger gate arrays in terms of capacity and performance.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other speed grades of the A54SX72A device, such as A54SX72A-1PQG208I for higher performance. Cross-family migration to newer Microchip PolarFire or IGLOO2 families requires schematic redesign but offers improved power efficiency and modern tooling support.
