A54SX16P-PQ208I

Overview

The A54SX16P-PQ208I is an antifuse-based Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It provides 24,000 system gates and supports up to 175 user I/Os in a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates with supply voltages of 2.5 V, 3.3 V, or 5 V, featuring mixed-voltage capability with 5 V input tolerance. It delivers system performance up to 250 MHz and internal clock frequencies up to 350 MHz. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Nonvolatile antifuse architecture providing single-chip integration without external configuration memory
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements
• Deterministic timing through patented metal-to-metal interconnects and dedicated routing resources
• Integrated security features including FuseLock technology to prevent reverse engineering

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems necessitating hot-swappable interface capabilities
• Secure embedded applications utilizing nonvolatile antifuse configuration
• Mixed-voltage logic interfacing between 2.5 V, 3.3 V, and 5 V components

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to the availability of counterfeits in the market. Confirm that the specific ordering suffix matches the required package type and temperature grade. Ensure compliance with current export control regulations and RoHS directives applicable to the manufacturing date code.

Selection Notes

Select this model for designs requiring high-speed deterministic performance with low pin count. The SX-A family offers superior register-to-logic ratios compared to standard CPLDs. Consider the fixed nature of antifuse technology when finalizing design changes, as reprogramming is not supported after fabrication.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series was designed to replace complex CPLDs and gate arrays in high-performance applications. Microchip Technology acquired Actel, integrating these devices into their broader programmable logic portfolio.

Replacement Considerations

Direct pin-compatible replacements are limited due to the proprietary antifuse architecture. Evaluate modern Microchip PolarFire or IGLOO families for updated features, though pinouts and voltage levels may differ significantly. Verify if legacy support tools remain available for migration.
