A54SX08-2PLG84

Overview

The Microsemi A54SX08-2PLG84 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It features 12,000 system gates and 768 logic modules. The device supports up to 130 user-programmable I/O pins and operates within a voltage range of 2.25V to 5.25V. It utilizes a Plastic Quad Flat Pack (PQFP) package with 208 leads. The -2 speed grade provides approximately 25% faster performance than the standard speed grade. The component is designed for mixed-voltage operation including 3.3V and 5V standards.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Features nonvolatile antifuse technology that prevents reverse engineering and eliminates configuration bitstream interception.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for in-system diagnostics.

Applications

• Complex programmable logic device (CPLD) integration
• Hardware security applications requiring design theft prevention
• Mixed-voltage interface designs supporting 3.3V and 5V standards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm availability status as legacy components may have limited supply chains. Ensure the required speed grade matches the system timing constraints before procurement.

Selection Notes

Select this model when 12,000 system gates are sufficient for the target logic density. The -2 speed grade is appropriate for designs requiring higher throughput than standard grades. Verify that the 208-pin PQFP package fits the PCB footprint and thermal requirements of the application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family offers deterministic timing and high-performance routing resources such as DirectConnect and FastConnect for optimized signal propagation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer for obsolescence management or equivalent capacity alternatives within the same product family.
