A54SX16-PQ208

Overview

The A54SX16-PQ208 is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 175 user-programmable I/O pins and features three global clock networks. It operates with supply voltages of 2.5 V, 3.3 V, or 5 V, enabling mixed-voltage operation with 5 V input tolerance.

Feature Summary

• Supports hot-swappable I/O configurations for safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources like DirectConnect.
• Includes Actel FuseLock security technology to prevent reverse engineering and unauthorized design access.

Applications

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

Procurement Notes

Verify the specific speed grade suffix when ordering, as blank indicates standard speed while -1 and -2 denote faster performance tiers. Confirm temperature range requirements against the commercial or industrial grades available in the PQFP package. Ensure the source documentation matches the manufacturer's official specifications for the SX-A series.

Selection Notes

Select this component for designs requiring high-performance logic density with low-power consumption. The architecture allows 100% pin locking and resource utilization, facilitating concurrent PCB development. Consider the internal clock capabilities and I/O flexibility when mapping complex digital functions onto the single-chip solution.

Part Context

This part belongs to the SX-A FPGA family, which utilizes antifuse technology for permanent configuration. The A54SX16A variant offers a balance between gate count and pin availability, positioned between the smaller A54SX08A and larger A54SX32A devices in terms of capacity and performance metrics.

Replacement Considerations

Direct substitutes include other members of the SX-A family such as the A54SX08A or A54SX32A if pin counts and logic resources allow. Verify that any replacement maintains the required speed grade and package type compatibility for the existing board layout.
