A54SX16A-TQG144M

Overview

The A54SX16A-TQG144M is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and 1,452 configurable logic blocks within a 144-pin Thin Quad Flat Pack (TQFP) package. The device operates at a maximum system frequency of 227 MHz with a standard speed grade. It supports a nominal supply voltage of 2.5 V, ranging from 2.25 V to 2.75 V, and includes 113 user-programmable I/O pins. The component is rated for military temperature grades, functioning between -55°C and +125°C.

Feature Summary

• Utilizes nonvolatile antifuse technology for permanent configuration without external memory.
• Supports hot-swap capabilities and flexible power-up sequencing for mixed-voltage I/O standards.
• Includes dedicated boundary-scan testing compliant with IEEE Standard 1149.1.

Applications

• Military and aerospace embedded systems requiring radiation-hardened or high-reliability logic.
• Industrial control applications involving mixed-voltage signal interfacing.
• Secure hardware designs utilizing FuseLock anti-tamper protection.

Procurement Notes

Verify the specific suffix 'M' confirms the military temperature range (-55°C to +125°C) as defined in the official ordering guide. Confirm RoHS compliance status through current manufacturer documentation, as packaging options may vary. Ensure the TQFP-144 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this model when military-grade thermal stability is required alongside the 24,000 gate capacity of the SX-A architecture. Compare against the commercial 'Blank' or industrial 'I' variants if environmental conditions are less severe. Verify that the 227 MHz speed grade meets the timing requirements for the intended digital logic implementation.

Part Context

This component belongs to the Actel SX-A series of single-chip FPGAs. It shares architectural similarities with other devices in the A54SX16A lineup, such as the A54SX16A-TQG144, differing primarily in the temperature grade suffix. The SX-A family is characterized by its metal-to-metal antifuse interconnect and deterministic performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with the A54SX16A-TQG144M datasheet for pin-compatible alternatives within the same package type if necessary.
