A54SX16A-TQ144M

Overview

The A54SX16A-TQ144M is a Field Programmable Gate Array from the Microchip Actel SX-A family, utilizing antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a TQFP-144 package. The device supports up to 113 user-programmable I/O pins and operates at a maximum system frequency of 227 MHz with an internal performance specification of 350 MHz. It functions on a single 2.5 V supply voltage (range 2.25 V to 2.75 V) and is rated for military temperature grades spanning -55°C to +125°C.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing.
• Support for mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards.
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1.

Applications

• Military and aerospace embedded control systems
• High-reliability industrial automation controllers
• Secure communication hardware requiring anti-tamper protection

Procurement Notes

Verify the specific suffix 'M' confirms the military temperature grade (-55°C to +125°C) as defined in the official ordering guide. Confirm RoHS compliance status via the manufacturer's current documentation, as packaging options may vary. Ensure the source document explicitly lists this part number to avoid confusion with standard commercial variants.

Selection Notes

Select this component when high reliability and radiation tolerance are required alongside deterministic timing. The military grade ensures stability across extreme environmental conditions. Verify that the 24,000 gate capacity meets design complexity needs and that the TQFP-144 package fits the PCB footprint constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnects. The family offers high-performance logic modules and dedicated clock networks. The A54SX16A variant specifically targets applications needing moderate logic density with robust security features against reverse engineering.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet or local source material. Cross-reference with other SX-A family members only if pin compatibility and resource requirements align, though speed grades and temperature ranges will differ.
