A54SX16P-1TQ144M

Overview

The A54SX16P-1TQ144M 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 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports up to 350 MHz internal performance with a maximum system frequency of 250 MHz. It features 113 user-programmable I/O pins and up to 2,012 dedicated flip-flops. Packaged in a 144-pin Thin Quad Flat Pack (TQFP), it operates within a military temperature range of -55°C to +125°C.

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 power sequencing requirements.
• Includes FuseLock™ security technology to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital signal processing requiring deterministic timing
• Secure embedded control systems needing anti-tamper protection
• Industrial automation interfaces supporting mixed voltage standards

Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the military temperature grade (-55°C to +125°C) as defined in the official Actel SX-A datasheet. Confirm that the package type matches the 144-pin TQFP specification. Ensure compliance with RoHS requirements if applicable to the manufacturing batch. Cross-reference the part number against current Microchip Technology product discontinuation notices.

Selection Notes

Select this component when designs require nonvolatile configuration without external memory chips. The SX-A architecture offers high resource utilization and pin-locking capabilities. Consider the military temperature rating for harsh environments. Evaluate the 24,000 gate capacity against logic complexity requirements before finalizing the selection.

Part Context

This part belongs to the Actel SX-A FPGA family, which integrates high-speed logic modules with patented antifuse technology. The SX-A series is designed for applications demanding low power consumption and high reliability. The A54SX16 variant specifically targets mid-range logic density needs within the broader portfolio.

Replacement Considerations

Direct replacements are limited due to the proprietary antifuse architecture. Verify compatibility with existing Actel Designer software tools. Alternative solutions may require significant redesign of the logic fabric and routing resources.
