A54SX16A-1PQG208M

Overview

The A54SX16A-1PQG208M is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and supports up to 175 user-programmable I/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology with a standard supply voltage of 2.5 V. It delivers 250 MHz system performance and 350 MHz internal performance. The component includes three global clock networks and complies with IEEE Standard 1149.1 for boundary-scan testing.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing insertion into active systems without power sequencing requirements or system degradation.
• Configurable I/O modules supporting mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards with individual slew rate control.
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources that minimize signal propagation delays.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays in industrial control systems.
• Secure embedded designs requiring protection against reverse engineering via FuseLock technology.
• PCI-compliant interfaces operating at 66 MHz with mixed-voltage I/O capabilities.
• Systems requiring hot-swappable functionality and deterministic timing for state machines or data path logic.

Procurement Notes

Verify the specific ordering suffix 'PQ' corresponds to the 208-pin Plastic Quad Flat Pack package type as defined in the official datasheet. Confirm that the speed grade '-1' meets the required timing constraints for the target application. Ensure compliance with RoHS packaging requirements if applicable to the procurement specifications.

Selection Notes

Select this device when 24,000 system gates are sufficient for the design logic. The PQFP package is suitable for surface-mount applications requiring gull-wing terminals. Consider the -1 speed grade for approximately 15% faster performance compared to the standard speed variant. Verify that the commercial temperature range aligns with the operational environment requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse-based nonvolatile architecture. The family ranges from 12,000 to 108,000 system gates, offering various package options including PQFP, TQFP, FBGA, and CQFP. The SX-A series is designed for low-power, high-performance applications where deterministic timing and security are critical.
