A54SX32A-2FGG144I

Overview

The A54SX32A-2FGG144I is an SX-A family Field Programmable Gate Array (FPGA) manufactured by Microsemi. It features 48,000 system gates and 2,880 logic modules within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at the -2 speed grade, providing approximately 25% faster performance than standard speed grades. It supports industrial temperature ranges from -40°C to +85°C. Key specifications include up to 111 user-programmable I/Os, three global clock networks, and support for mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile antifuse architecture enabling deterministic timing and high-speed signal propagation through metal-to-metal interconnects.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 for in-system diagnostic verification.
• Configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up states.

Applications

• High-performance digital logic integration requiring deterministic timing characteristics
• Industrial control systems operating within extended temperature environments
• PCI-compliant interface designs supporting 66 MHz bus speeds
• Secure embedded applications utilizing FuseLock technology to prevent reverse engineering

Procurement Notes

Verify the specific ordering suffix against official Microsemi documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with Actel Designer software versions supporting the SX-A family. Confirm RoHS compliance status if required for your manufacturing process. Check for any product discontinuation notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when 48,000 system gates and 2,880 logic modules are sufficient for the design. The -2 speed grade offers higher performance than standard grades but lower than -1 grades. The FBGA144 package is suitable for space-constrained PCB layouts. Verify that the industrial temperature range meets environmental requirements. Consider pin count availability for all necessary I/O functions before finalizing the selection.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series provides a single-chip solution for low-power, high-performance designs. The A54SX32A variant specifically targets applications requiring moderate logic density with robust I/O flexibility and security features inherent to antifuse-based architectures.

Replacement Considerations

Direct replacements must match the 48,000 system gate capacity, FBGA144 package, and industrial temperature grade. Verify speed grade equivalence for the -2 designation. Cross-reference with other SX-A family members like A54SX32A-FGG144I only if package and speed differences are acceptable. Consult Microsemi for current alternative recommendations as legacy parts may have limited availability.
