A54SX16-1PQ208

Overview

The Microsemi A54SX16-1PQ208 is a nonvolatile Field Programmable Gate Array 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) package. The device operates at an industrial temperature range of -40°C to +85°C with a standard speed grade designation of -1. Internal architecture includes 1,452 logic modules comprising combinatorial cells and dedicated flip-flops, supported by three global clock networks for high-performance signal routing.

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.
• Configurable mixed-voltage operation supporting 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance and drive strength.
• Deterministic timing performance enabled by DirectConnect and FastConnect local routing resources minimizing propagation delays.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces including 66 MHz PCI compliance
• DSP and co-processor functions requiring low-power integration

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm that the component matches the required speed grade and pinout specifications for the target application design.

Selection Notes

Select this model when a nonvolatile FPGA with deterministic timing and hot-swap capabilities is required. Ensure the design utilizes the available global clocks and I/O standards compatible with the specified voltage levels.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, high-performance applications. The family integrates logic previously found in multiple CPLDs and gate arrays onto a single chip, reducing time-to-market and board space requirements.

Replacement Considerations

Compatible alternatives within the same product line include the A54SX08A and A54SX32A devices. These parts share the same SX-A architecture and PQFP package options but offer different logic capacities and I/O counts.
