A54SX32A-PQG208

Overview

The A54SX32A-PQG208 is a nonvolatile Field Programmable Gate Array (FPGA) from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 174 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device features 1,452 combinatorial cells and up to 990 dedicated flip-flops. It operates with internal clock frequencies reaching 350 MHz and delivers 250 MHz system performance. The architecture includes three global clock networks and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation delays.
• Integrated security via FuseLock technology preventing reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration replacing complex gate arrays
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Systems requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific speed grade suffix corresponds to required timing constraints. Check for RoHS compliance status if environmental regulations apply. Ensure the PQFP-208 package dimensions match PCB footprint specifications. Validate that the commercial temperature grade meets operational environment requirements.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. Choose the PQFP-208 package for surface-mount assembly compatibility. Verify that the standard speed grade meets the maximum operating frequency requirements of the application. Consider the Industrial or Automotive grades if extended temperature ranges are necessary instead of the Commercial grade.

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 utilizes antifuse technology rather than SRAM-based configuration, offering inherent security and nonvolatility. This specific part represents the mid-range capacity option within the family, balancing resource density with high-speed performance characteristics.

Replacement Considerations

Direct replacements include other speed grades of the A54SX32A device such as A54SX32A-1PQG208 or A54SX32A-2PQG208 for faster performance. Alternative packages like TQFP-208 are available if pin counts allow. For higher capacity needs, the A54SX72A series serves as an upward migration path within the same architectural family.
