A54SX16P-2PQG208

Overview

The A54SX16P-2PQG208 is a nonvolatile 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 configurable logic blocks (CLBs). The device supports up to 350 MHz internal performance and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It features 175 user-programmable I/Os in a 208-pin Plastic Quad Flat Pack (PQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Includes dedicated clock networks (HCLK, CLKA, CLKB) and specialized routing resources like DirectConnect and FastConnect for deterministic timing.

Applications

• High-performance digital logic integration replacing complex CPLDs
• PCI-compliant interface designs requiring 66 MHz support
• Systems requiring hot-swappable capabilities and power-up/down flexibility

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the component matches the required speed grade and pinout specifications for your application design.

Selection Notes

Select this model when 24,000 system gates and 175 user I/Os are required in a PQFP package. Ensure the design utilizes the SX-A architecture's unique antifuse programming and nonvolatile characteristics. Verify voltage domain requirements match the supported 2.5 V, 3.3 V, or 5 V options.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, high-performance applications. The family includes devices ranging from 8,000 to 108,000 system gates, offering various package options including PQFP, TQFP, and BGA types.

Replacement Considerations

Direct replacements within the same package and pin count include other A54SX16 variants with different speed grades or temperature ratings, such as A54SX16A-2PQG208. Cross-family migration may require significant redesign due to architectural differences.
