A54SX16P-2TQ176I

Overview

The A54SX16P-2TQ176I 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 1452 Configurable Logic Blocks (CLBs) and 16,000 typical system gates. The device supports a maximum internal clock frequency of 350 MHz with a system performance of 250 MHz. It features up to 924 dedicated flip-flops and accommodates 147 user-programmable I/Os in its 176-pin Thin Quad Flat Pack (TQFP) package. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources
• Provides nonvolatile single-chip solution with Actel FuseLock security technology

Applications

• 66 MHz PCI compliant designs
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing
• Systems requiring mixed-voltage I/O interfacing

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 vary by manufacturing batch. Ensure design tools support the SX-A antifuse architecture for programming.

Selection Notes

Select this model for applications requiring high-speed logic with 16,000 system gates and industrial temperature stability. Compare pin counts and I/O configurations against alternative packages like PQFP or FBGA if board space constraints differ. Verify that the 176-pin TQFP footprint matches the target PCB layout requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers various gate densities ranging from 8,000 to 108,000 system gates across different device sizes, providing a versatile platform for low-power, high-performance digital designs.

Replacement Considerations

Check for other speed grades within the A54SX16A series, such as standard or faster variants, if timing requirements change. Consider higher capacity devices like the A54SX32A if additional logic resources are needed. Verify package compatibility when substituting with other pin counts in the same family.
