A54SX16-PQ208I

Overview

The Microsemi A54SX16-PQ208I is a nonvolatile Field Programmable Gate Array from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and features a 'sea-of-modules' architecture with 1,452 logic modules comprising combinatorial cells and dedicated flip-flops. The device supports up to 175 user-programmable I/Os in a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates within an industrial temperature range of -40°C to +85°C and delivers internal clock frequencies up to 350 MHz.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements for supply voltages.
• Configurable I/O support for mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance.
• Actel Secure Programming Technology with FuseLock prevents reverse engineering and unauthorized design theft.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm that the component meets required environmental standards such as RoHS if applicable. Ensure the source document matches the exact part number to validate speed grade and pin compatibility before procurement.

Selection Notes

Select this model when a nonvolatile FPGA with deterministic timing and high performance is required. The SX-A architecture offers optimal register-to-logic mix for complex designs. Consider the 208-pin PQFP package constraints and verify that the 175 available user I/Os meet interface requirements for the target application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, and high-performance applications. The family utilizes antifuse technology to provide secure, nonvolatile configuration without external memory. The A54SX16 variant sits between the smaller A54SX08 and larger A54SX32 devices in terms of logic capacity.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by checking pinout and electrical specifications against alternative SX-A family members or other antifuse-based FPGAs.
