A54SX08-1TQG144

Overview

The A54SX08-1TQG144 is a Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It features 768 logic modules and approximately 12,000 system gates. The device supports up to 113 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The component supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.

Feature Summary

• Supports hot-swap capabilities for most I/O standards, allowing insertion into active systems without power sequencing requirements.
• Features deterministic timing through unique local routing resources like DirectConnect and FastConnect for predictable signal propagation.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing (JTAG) for in-system diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile configuration
• Systems requiring mixed-voltage I/O interfacing between 2.5V, 3.3V, and 5V components
• Industrial or commercial applications needing hot-swappable peripheral interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the 'I' suffix corresponds to the required industrial temperature range (-40°C to +85°C). Ensure the TQFP package dimensions match the target PCB footprint specifications.

Selection Notes

Select this model when 12,000 system gates are sufficient for the design complexity. The -1 speed grade offers approximately 15% faster performance than the standard grade. Verify that the 144-pin TQFP package fits the available board space and that the pin count accommodates all necessary I/O connections.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, which are built on 0.22/0.25 micron CMOS antifuse technology. The SX-A series is characterized by its high-speed metal-to-metal interconnects and nonvolatile nature, eliminating the need for external configuration memory chips common in SRAM-based FPGAs.

Replacement Considerations

Cross-reference with other A54SX08 variants such as A54SX08-TQ144 or A54SX08A-TQ144. Note that the 'A' suffix indicates a specific revision within the SX-A family. Verify speed grades and temperature ratings before substitution to ensure functional equivalence.
