A54SX32A-2TQG144I

Overview

The A54SX32A-2TQG144I is an SX-A family Field Programmable Gate Array featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum system frequency of 250 MHz with internal performance up to 350 MHz. The device provides 113 user-programmable I/Os in a 144-pin Thin Quad Flat Pack (TQFP) package. It supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. The industrial temperature grade (-40°C to +85°C) is indicated by the 'I' suffix.

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 Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 for diagnostic verification
• Configurable weak-resistor pull-up or pull-down capabilities for defined I/O states during power-up

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Secure embedded designs utilizing FuseLock technology

Procurement Notes

Verify the specific speed grade '-2' designation corresponds to approximately 25% faster performance than standard speed within the SX-A family. Confirm that the TQFP-144 package dimensions align with your PCB footprint requirements. Ensure the industrial temperature range specification meets your operational environment constraints before finalizing procurement.

Selection Notes

Select this model when 48,000 system gates are required alongside 113 available I/O pins. The -2 speed grade is suitable for applications needing higher throughput than standard grades while maintaining compatibility with the SX-A ecosystem. Consider the TQFP-144 package if surface-mount thin-profile constraints exist compared to BGA options.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22/0.25 micron CMOS antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a nonvolatile single-chip solution. The A54SX32A variant specifically targets mid-range complexity designs requiring robust I/O flexibility and secure programming features.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing design tools such as Actel Designer software when considering alternative speed grades or package variants within the same SX-A family.
