A54SX16A-TQ144I

Overview

The A54SX16A-TQ144I is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It provides up to 113 user-programmable I/O pins and includes boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG). The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swappable I/Os for safe insertion into active systems without power sequencing requirements.
• Includes FuseLock™ security technology to prevent reverse engineering and unauthorized design access.
• Features deterministic timing with individual output slew rate control and configurable weak-resistor pull-ups or pull-downs.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions.
• Systems requiring hot-swap capability and compliance with 66 MHz PCI standards.
• Applications needing secure programming and protection against design theft.

Procurement Notes

Verify the specific ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) as defined in the manufacturer's documentation. Confirm that the TQFP-144 package dimensions match the target PCB footprint. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture before initiating procurement.

Selection Notes

Select this model when 24,000 system gates and 1,452 CLBs are required within a 144-pin form factor. The Industrial temperature grade is suitable for environments exceeding commercial limits. Consider the 250 MHz system performance limit for timing closure. Verify that the antifuse technology aligns with the permanent configuration needs of the application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect elements. The SX-A series offers high-density logic resources with low-power consumption. The A54SX16A variant specifically targets designs needing moderate gate counts with robust I/O flexibility and security features inherent to antifuse-based architectures.
