A54SX08-VQ100

Overview

The Microsemi A54SX08-VQ100 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It provides 12,000 system gates and 768 logic modules, including 512 dedicated flip-flops. The device supports up to 81 user-programmable I/O pins and operates within a voltage range of 2.25V to 5.25V. It features a maximum system performance of 250 MHz with internal clock frequencies reaching 350 MHz. The component is housed in a 100-pin Thin Quad Flat Pack (TQFP) package and supports industrial temperature grades ranging from -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent interconnection.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Configurable mixed-voltage I/O support for 3.3V, 5V PCI, 5V TTL, and 2.5V LVCMOS standards.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays.
• Industrial control systems requiring deterministic timing and hot-swappable capabilities.
• Embedded designs needing secure, nonvolatile configuration without external bitstream memory.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options may vary. Ensure design tools are compatible with the SX-A family architecture before procurement.

Selection Notes

Select this model when 12,000 system gates and 81 I/Os meet design requirements. Consider the VQ100 package only if a 100-pin TQFP footprint is available on the PCB. Verify that the required operating frequency does not exceed the standard speed grade limits for the chosen temperature range.

Part Context

This component belongs to the Actel/Microsemi SX-A family of antifuse FPGAs. It shares architectural similarities with the A54SX16A and A54SX32A but offers lower logic density. The SX-A series is characterized by its high-speed metal-to-metal interconnects and robust security features inherent to antifuse technology.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be verified via official substitution lists. Cross-family migration to ProASIC3 or PolarFire requires significant schematic and software redesign due to differing architectures and I/O configurations.
