A54SX08-1PLG84I

Overview

The A54SX08-1PLG84I is an industrial-grade FPGA from the SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25V to 5.25V and supports up to 130 user I/Os in a 208-pin PQFP package. The device achieves a maximum system performance frequency of 250 MHz with internal clock speeds reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• Industrial control systems requiring deterministic timing and high reliability.
• Military and aerospace applications utilizing industrial temperature grade components.
• Complex digital logic integration replacing multiple CPLDs or gate arrays.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) as defined in the datasheet. Confirm the package type corresponds to the 208-pin Plastic Quad Flat Pack (PQFP). Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture before procurement.

Selection Notes

Select this component when 12,000 system gates are sufficient for the design logic. The -1 speed grade offers approximately 15% faster performance than the standard grade. Consider the 208-pin PQFP package constraints regarding board space and thermal dissipation. Verify that the required I/O standards match the configurable options available on the SX-A platform.

Part Context

This part belongs to the Microsemi (formerly Actel) SX-A family of FPGAs. It represents a mid-range capacity device within the series, positioned below the A54SX16A and A54SX32A models. The SX-A family is characterized by its use of metal-to-metal programmable antifuse technology rather than SRAM-based configuration.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other speed grades of the A54SX08A series, such as the standard speed variant. Cross-family migration to PolarFire or SmartFusion devices requires significant schematic and code redesign due to architectural differences.
