A54SX32A-1FG144I

Overview

The A54SX32A-1FG144I is an SX-A family Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. 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 an industrial temperature range of -40°C to +85°C and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. Key specifications include up to 111 user-programmable I/Os, three global clock networks, and compliance with IEEE 1149.1 Boundary Scan Testing.

Feature Summary

• Nonvolatile antifuse architecture providing deterministic timing and high security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Integrated Silicon Explorer II for in-system diagnostic verification and boundary scan testing

Applications

• Industrial control systems requiring deterministic performance and robust I/O capabilities
• Secure embedded applications utilizing nonvolatile configuration and anti-tamper features
• High-speed data path logic and state machine implementations leveraging fast interconnect resources

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix indicates RoHS-compliant packaging if required. Ensure the FBGA144 footprint matches the target PCB design constraints. Check current availability status as older speed grades may have limited supply chains.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The -1 speed grade offers approximately 15% faster performance than standard speed. Consider the FBGA144 package for space-constrained applications requiring fine-pitch connections. Verify that the 111 available user I/Os meet the interface requirements for the target system.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for low-power, high-performance single-chip solutions. The A54SX32A variant specifically provides 48,000 system gates, positioning it between the smaller A54SX16A and larger A54SX72A devices in terms of capacity.

Replacement Considerations
