A54SX16A-FTQG100

Overview

The A54SX16A-FTQG100 is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a 100-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 81 user-programmable I/O pins and features three global clock networks. It operates with internal clock frequencies up to 350 MHz and system performance up to 250 MHz. The component supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, ensuring compatibility with various interface standards.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Configurable I/O support for multiple voltage standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays.
• Systems requiring hot-swappable capabilities and power-up/down flexibility without voltage sequencing.
• Applications needing secure design protection against reverse engineering via FuseLock technology.

Procurement Notes

Verify the specific speed grade suffix associated with the FTQG100 designation, as standard SX-A ordering typically uses F, Std, -1, or -2. Confirm that the Industrial temperature grade (I) matches the required operational range of -40°C to +85°C. Ensure the RoHS compliance status aligns with current environmental regulations for the target market.

Selection Notes

Select this device when 24,000 system gates are sufficient for the design complexity. Consider the TQFP-100 package constraints regarding pin count and thermal dissipation. Evaluate if the 81 available user I/Os meet the interface requirements. Verify that the antifuse programming infrastructure is compatible with the chosen design tools.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which was later acquired by Microchip Technology. The SX-A series is characterized by its high-speed antifuse technology and deterministic performance. The A54SX16A variant specifically targets designs requiring moderate logic density with high-speed processing capabilities.

Replacement Considerations

Direct replacements include other speed grades within the A54SX16A series such as A54SX16A-F, A54SX16A-Std, or A54SX16A-1, provided the package and temperature grade match. Cross-family migration to newer Microchip FPGA architectures may require significant design rework due to architectural differences.
