A54SX08A-2TQG100

Overview

The A54SX08A-2TQG100 is an antifuse-based Field Programmable Gate Array from the Microchip SX-A family, housed in a 100-pin Thin Quad Flat Pack (TQFP) package. It provides 12,000 system gates and supports up to 81 user-programmable I/Os. The device operates within a voltage range of 2.25V to 5.25V and features a speed grade of -2, delivering approximately 25% faster performance than standard devices. It includes 768 logic modules with dedicated flip-flops and supports mixed-voltage operation with 5V input tolerance.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing safe insertion into electrically active systems without power sequencing requirements.
• Deterministic timing performance enabled by patented DirectConnect and FastConnect routing resources that minimize signal propagation delays.

Applications

• High-performance digital logic integration requiring deterministic timing and low latency
• Systems requiring hot-swappable interface capabilities and flexible power-up/down sequences
• Industrial and automotive applications necessitating robust security against reverse engineering

Procurement Notes

Verify the specific ordering suffixes to confirm the package type, speed grade, and temperature rating match the design requirements. Ensure compatibility with the Actel Designer software version used for programming. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed internal clocking is required. The -2 speed grade offers improved performance over standard variants. Consider the 100-pin TQFP package constraints regarding pin count and thermal dissipation. Verify that the 81 available I/Os meet the interface requirements for the target application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse technology and high-density logic blocks. The A54SX08A variant represents the entry-level capacity within this family, offering 12,000 system gates. It shares architectural features with larger devices like the A54SX16A and A54SX32A but has fewer I/O pins and logic resources.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX08A series, such as the -1 or Standard speed variants, provided timing requirements allow. Cross-family migration to newer Microchip FPGA architectures requires significant redesign due to differences in configuration technology and I/O standards.
