A54SX08A-PQ208

Overview

The Microsemi A54SX08A-PQ208 is a nonvolatile FPGA from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and 768 logic modules (comprising 512 combinatorial cells and 256 dedicated flip-flops). The device supports up to 130 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates with supply voltages of 2.5 V, 3.3 V, or 5 V, enabling mixed-voltage operation with 5 V input tolerance. The architecture includes three global clock networks and features hot-swap compliant I/Os for power-up/down flexibility.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os that tristate during power-up/down without requiring specific voltage sequencing.
• Configurable I/O support for multiple standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the complete part number against official datasheets to confirm speed grade and temperature range suffixes. Confirm RoHS compliance status if lead-free packaging is required. Ensure design tools are compatible with the SX-A family architecture before procurement.

Selection Notes

Select this device for designs requiring nonvolatile configuration and mixed-voltage I/O capabilities. Consider the 12,000 system gate capacity and 130 I/O limit for moderate complexity applications. Verify thermal requirements against the PQFP package specifications.

Part Context

The A54SX08A belongs to the Actel SX-A family of FPGAs, which were acquired by Microsemi. This family utilizes antifuse technology rather than SRAM-based configuration, offering inherent security and nonvolatility. The PQ208 designation indicates the 208-pin Plastic Quad Flat Pack package option available for this device density.

Replacement Considerations

Public confirmed substitute part numbers: A54SX08-TQ208, A54SX08-PQG208.
