A54SX08A-1FG144I

Overview

The A54SX08A-1FG144I is a Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It features 768 logic modules and 12,000 system gates. The device supports up to 111 user-programmable I/O pins and includes 512 dedicated flip-flops. It operates within a voltage range of 2.25V to 5.25V and supports an industrial temperature grade of -40°C to +85°C. The component is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Includes deterministic timing capabilities with individual output slew rate control and configurable weak-resistor pull-up or pull-down at power-up.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions.
• Systems requiring hot-swappable interface capabilities without supply voltage sequencing.
• Industrial applications necessitating operation across extended temperature ranges (-40°C to +85°C).

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, speed grade, and temperature rating. Ensure compatibility with existing design constraints regarding pin count and I/O voltage levels before procurement.

Selection Notes

Select this model when 12,000 system gates and 111 user I/Os are required within a compact FBGA footprint. Consider the -1 speed grade for performance approximately 15% faster than standard variants. Verify that the industrial temperature range meets environmental specifications.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers high-density logic resources with low power consumption and robust security features against reverse engineering through FuseLock technology.

Replacement Considerations

Check for other speed grades within the A54SX08A series or alternative packages such as PQFP or TQFP if pin counts allow. Verify functional equivalence with A54SX08A variants having different temperature or packaging suffixes.
