A54SX16P-1TQ176

Overview

The A54SX16P-1TQ176 is a Field Programmable Gate Array from the Actel 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, including 924 combinatorial cells and 528 dedicated flip-flops. The device supports up to 350 MHz internal performance with a maximum clock frequency of 250 MHz. It features 147 user I/Os in a 176-pin Thin Quad Flat Pack (TQFP) package. The component operates at 2.5 V, 3.3 V, or 5 V with mixed-voltage support and includes three global clock networks.

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 active systems without power sequencing requirements.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.
• Actel FuseLock security technology preventing reverse engineering and unauthorized design access.

Applications

• 66 MHz PCI compliant integration
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the -1 speed grade designation aligns with project timing requirements, as it offers approximately 15% faster performance than standard grades. Ensure the TQFP package availability matches the target PCB footprint specifications.

Selection Notes

Select this model when a nonvolatile FPGA with high-speed deterministic timing is required. The -1 speed grade is suitable for designs needing approximately 15% faster performance than standard devices. Verify that the 176-pin TQFP package fits the board layout constraints and that the 147 available user I/Os meet interface requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, and high-performance applications. The SX-A series utilizes antifuse technology to provide a robust, secure, and nonvolatile programming solution compared to volatile SRAM-based FPGAs.
