A54SX08-1PQG208

Overview

The Microsemi A54SX08-1PQG208 is an antifuse-based Field Programmable Gate Array (FPGA) belonging to the SX-A family. It features a capacity of 12,000 system gates and 768 logic modules. The device supports up to 130 user-programmable I/O pins and includes 512 dedicated flip-flops. It operates within a voltage range of 2.25V to 5.25V and is available in a 208-pin Plastic Quad Flat Pack (PQFP) package. The -1 speed grade indicates performance approximately 15% faster than the standard speed grade.

Feature Summary

• Supports mixed-voltage operation with 5 V input tolerance and drive strength across 2.5 V, 3.3 V, and 5 V supplies.
• Features hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions.
• Systems requiring hot-swappable interface capabilities for continuous operation during maintenance.
• Applications needing secure hardware implementation protected against unauthorized access or probing.

Procurement Notes

Verify the specific ordering suffixes to confirm temperature grade and packaging compliance. The 'I' suffix denotes Industrial temperature range (-40°C to +85°C), while the absence of a letter typically indicates Commercial range. Confirm RoHS compliance status via the 'G' suffix if required. Cross-reference datasheet version v5.3 for accurate specifications.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices. Ensure the design fits within the 12,000 system gate limit and 130 I/O constraint. Verify that the PQFP208 package dimensions align with the PCB footprint requirements. Consider the -1 speed grade if higher internal clock frequencies are necessary compared to the standard grade.

Part Context

This part belongs to the Actel/Microsemi SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse technology. Unlike volatile FPGAs, these devices retain configuration data without external memory. The A54SX08 variant represents the entry-level capacity within the family, offering a balance of logic density and pin count for compact embedded applications.

Replacement Considerations

Direct replacements include other variants within the SX-A family such as the A54SX08A series. For different speed grades, consider the A54SX08-Std or A54SX08-2 equivalents. Package variations like TQFP or PBGA exist but require schematic modifications. No direct cross-family substitutes from other manufacturers share identical antifuse architecture and pinout compatibility.
