A54SX16A-1FGG144M

Overview

The A54SX16A-1FGG144M is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and contains 1,452 logic modules with 924 combinatorial cells and 528 dedicated flip-flops. The device supports up to 111 user-programmable I/Os and features three global clock networks. It operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. The -1 speed grade offers approximately 15% faster performance than standard grades, achieving up to 250 MHz system performance. It utilizes a 144-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down in any order without sequencing requirements or damage to the host system.
• Enables deterministic timing through unique local routing resources including DirectConnect and FastConnect for predictable signal propagation.
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) and FuseLock™ security technology to prevent reverse engineering.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Secure designs needing protection against reverse engineering

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm its exact definition regarding packaging or qualification. Confirm current availability status as legacy antifuse products may have limited supply chains. Ensure compatibility with existing Actel Designer software versions for programming and place-and-route operations.

Selection Notes

Select this component when 24,000 system gates and 111 I/Os are required in a compact FBGA form factor. The -1 speed grade is suitable for applications needing moderate performance improvements over standard speeds. Verify that the 2.5 V core voltage aligns with the system's power delivery infrastructure and I/O standards.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance applications. The family includes devices ranging from 8,000 to 108,000 system gates, sharing a common architecture based on antifuse technology and similar I/O configurations across different pin counts.

Replacement Considerations

Direct replacements are not explicitly listed in the provided datasheet. Consider other parts within the A54SX16A series with different speed grades (-F, Std, -2) or packages (TQFP, PBGA) if pinout or performance adjustments are needed. Consult Microchip for obsolete product transitions.
