A54SX32A-2PQ208

Overview

The A54SX32A-2PQ208 is a nonvolatile Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 174 user-programmable I/Os in its 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at a standard supply voltage of 2.5 V with a range of 2.25 V to 2.75 V. It features three global clock networks and achieves a maximum system performance frequency of 250 MHz. The component is designed for mixed-voltage operation supporting 3.3 V and 5 V I/O standards.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap capabilities allowing insertion into active systems without degrading host reliability or requiring specific power sequencing.
• Includes dedicated routing resources such as DirectConnect and FastConnect to minimize signal propagation delays within logic clusters.
• Compliant with IEEE Standard 1149.1 (JTAG) for boundary-scan testing and includes Actel Secure Programming Technology to prevent reverse engineering.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Systems requiring deterministic timing and fast state machine execution
• Hot-swappable hardware configurations and cold-sparing applications

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required performance level, as it indicates approximately 25% faster operation than the standard grade. Confirm that the PQFP package type matches the PCB footprint requirements. Ensure the design accounts for the nonvolatile nature of the antifuse technology, which does not support reprogramming once configured.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The -2 speed grade is appropriate for designs requiring higher throughput than the standard version. Verify that the 208-pin PQFP package fits the available board space and thermal constraints. Consider the availability of 3.3 V and 5 V I/O compatibility if interfacing with legacy components.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their high-density antifuse architecture. The A54SX32A variant sits between the A54SX16A and A54SX72A in terms of capacity. The SX-A family is known for its sea-of-modules architecture and low-power consumption relative to its performance class.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current equivalent recommendations or migration paths from discontinued antifuse devices.
