A54SX16P-1TQG144I

Overview

The A54SX16P-1TQG144I is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It contains 1,452 Configurable Logic Blocks (CLBs) and provides 24,000 system gates. The device supports a maximum system performance of 250 MHz with internal clock frequencies reaching 350 MHz. It features up to 113 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.
• Provides nonvolatile single-chip configuration secured by FuseLock™ technology to prevent reverse engineering.

Applications

• High-performance digital logic integration requiring low power consumption
• PCI-compliant interface designs operating at 66 MHz
• Systems requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Ensure compatibility with Actel Designer software versions supporting the SX-A family. Check for end-of-life status or alternative sourcing options as older antifuse devices may have limited production availability.

Selection Notes

Select this model when 24,000 system gates and 144-pin TQFP packaging are required for industrial applications. Consider the -1 speed grade for approximately 15% faster performance than standard grades. Verify that the design utilizes the available global clocks and does not exceed the 113 user I/O limit for this specific package variant.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family offers high-density logic modules arranged in clusters and superclusters to optimize silicon utilization. The SX-A series is designed for cost-effective, single-chip solutions integrating CPLD and FPGA functionalities with low power consumption.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current equivalent offerings or migration paths from discontinued antifuse-based SX-A devices.
