A54SX08-1VQ100

Overview

The A54SX08-1VQ100 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microsemi. It features a capacity of 12,000 system gates, organized into 768 logic modules comprising 512 combinatorial cells and 256 dedicated flip-flops. The device supports up to 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. It operates with a supply voltage range of 2.25 V to 5.25 V and is rated for industrial temperature grades (-40°C to +85°C). The -1 speed grade indicates performance approximately 15% faster than the standard speed variant.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Includes IEEE 1149.1 (JTAG) boundary-scan testing capabilities and FuseLock security features to prevent reverse engineering.

Applications

• Industrial control systems requiring deterministic timing and nonvolatile logic integration
• Automotive electronics operating under extended temperature conditions
• Military and aerospace applications necessitating radiation-hardened or high-reliability programmable logic

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 compatibility with the SX-A family architecture before procurement.

Selection Notes

Select this component when a nonvolatile FPGA with moderate gate density and fast pin-to-pin timing is required. Consider the -1 speed grade for designs needing higher performance than the standard variant. Verify that the 100-pin TQFP package fits the PCB footprint constraints and that the I/O count meets interface requirements.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are built on 0.22/0.25 micron CMOS antifuse technology. The family offers high-performance logic with low power consumption and robust security features, targeting applications where instant-on capability and resistance to reverse engineering are critical.

Replacement Considerations

Direct replacements must be sought within the SX-A family or compatible Actel/Microsemi antifuse FPGAs. Verify pinout compatibility and logical resource equivalence. Note that speed grades and temperature ranges differ between variants; ensure the substitute matches the electrical and environmental specifications of the original design.
