A54SX32A-TQ144M

Overview

The A54SX32A-TQ144M is a nonvolatile Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 typical system gates and 2,880 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/Os and operates with a supply voltage range of 2.25 V to 2.75 V. It features a maximum operating frequency of 238 MHz and is rated for military temperature grades spanning -55°C to +125°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent configuration without volatile bitstreams.
• Supports hot-swap capabilities allowing insertion into active systems without power sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic signal propagation.
• Integrates boundary-scan testing compliant with IEEE Standard 1149.1 for diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile storage
• Systems demanding hot-swappable interface compatibility
• Military applications requiring extended temperature operation ranges

Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the required military temperature grade (-55°C to +125°C). Confirm that the TQFP-144 package dimensions align with the target PCB footprint. Ensure design tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this component when 48,000 system gates are sufficient for the design complexity. Consider the 144-pin TQFP package constraints regarding pin count and thermal dissipation. Verify that the 2.5 V core voltage requirement matches the available power rails in the target system environment.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for high-speed, secure, and nonvolatile logic implementation. The SX-A series is designed for applications requiring deterministic performance and robust security against reverse engineering through FuseLock technology.
