A54SX32A-FGG144

Overview

The A54SX32A-FGG144 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum clock frequency of 172 MHz with a typical combinatorial delay of 1.7 ns. The device utilizes a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V, with 5 V input tolerance. The component is RoHS compliant and designed for commercial temperature ranges.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without voltage sequencing requirements
• Provides deterministic timing through user-controllable delays and 100% pin locking with full resource utilization
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for in-system diagnostics
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• 66 MHz PCI compliant single-chip solutions
• Low-power high-performance designs requiring mixed-voltage interfaces
• Applications necessitating secure programming and anti-tamper protection

Procurement Notes

Verify the specific speed grade suffix and temperature range code associated with the FGG144 package variant. Confirm RoHS compliance status and check for any product change notifications or discontinuation notices relevant to this Microsemi/Actel part number before finalizing procurement plans.

Selection Notes

Select this model when 48,000 system gates and 2,880 logic modules are required within a 144-pin FBGA footprint. Ensure the design utilizes 2.5 V, 3.3 V, or 5 V I/O standards compatible with the SX-A architecture. Verify that the 172 MHz performance meets the system timing constraints.

Part Context

This component belongs to the Actel SX-A family of antifuse-based FPGAs. The SX-A series is characterized by its metal-to-metal programmable interconnects and sea-of-modules architecture. This family offers nonvolatile configuration and supports various temperature grades and package options for industrial and commercial applications.

Replacement Considerations

Check for discontinued status and potential obsolescence. Consider equivalent parts from the same SX-A family with different speed grades or packages if available. Verify compatibility with existing design tools and programming hardware.
