A54SX16-2PQ208

Overview

The Microsemi A54SX16-2PQ208 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 24,000 system gates and supports up to 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP). The device features 1,452 logic modules, including combinatorial cells and dedicated flip-flops, with three global clock networks. It operates at a maximum internal frequency of 350 MHz and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Supports hot-swap operations for most I/O configurations without requiring specific power sequencing.
• Includes Actel FuseLock security technology to prevent reverse engineering and unauthorized design access.
• Features deterministic timing through metal-to-metal programmable antifuse interconnect elements.
• Complies with IEEE Standard 1149.1 for boundary-scan testing via JTAG interface.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces requiring mixed-voltage compatibility
• DSP and co-processor functions in embedded designs

Procurement Notes

Verify the specific speed grade suffix '-2' corresponds to the required performance level, as it indicates approximately 25% faster operation than standard speed. Confirm the package type PQFP matches the PCB footprint requirements. Check RoHS compliance status if lead-free packaging is mandatory for the assembly process.

Selection Notes

Select this model when 24,000 system gates are sufficient for the logic density requirements. Ensure the design utilizes the available 175 user I/Os effectively. Consider the -2 speed grade if higher internal clock frequencies near 350 MHz are necessary compared to standard or slower grades.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for permanent configuration. The A54SX16A variant specifically offers 24,000 system gates, positioning it between the smaller A54SX08A and larger A54SX32A devices in terms of capacity and resource availability.

Replacement Considerations

Compatible substitutes include other variants within the SX-A family such as A54SX08A or A54SX32A, provided the gate count and pinout constraints allow for adaptation. Verify that any replacement maintains the PQFP package form factor and meets the specific electrical and timing specifications required by the application.
