A54SX32A-PQ208M

Overview

The A54SX32A-PQ208M is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 174 user I/Os in its 208-pin PQFP package. The device operates at a standard speed grade with internal clock frequencies reaching 350 MHz. It features mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V standards, including PCI compliance. The military temperature grade (-55°C to +125°C) ensures reliability in harsh environments.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap capabilities and power-up/down friendly operation, allowing supply voltages to be powered in any order without sequencing requirements.
• Includes deterministic routing resources such as DirectConnect and FastConnect to minimize signal propagation delays within logic clusters.
• Integrates boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for superior diagnostic and verification capabilities.

Applications

• Military and aerospace systems requiring radiation tolerance and wide temperature range operation
• High-speed data path logic and state machines utilizing fast local routing resources
• PCI-compliant interface designs supporting 66 MHz bus speeds
• Secure embedded applications protected by Actel Secure Programming Technology

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm availability status as legacy antifuse products may have limited production runs or end-of-life notices. Ensure design tools are compatible with the SX-A architecture before procurement.

Selection Notes

Select this component when nonvolatile configuration is required to eliminate external boot devices. Choose the PQ208 package for high pin count density in surface-mount applications. Verify that the 48,000 system gate capacity meets the logic resource requirements of the target design. Ensure the design toolchain supports the specific speed grade and temperature rating selected.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology rather than SRAM-based configuration. The SX-A series was designed to replace complex CPLDs and gate arrays in high-performance applications. Microchip Technology acquired Actel, continuing support for these antifuse devices.

Replacement Considerations

Direct replacements are limited due to the proprietary antifuse architecture. Consider Microchip RT ProASIC3 or RT Fusion families for similar nonvolatile FPGA requirements. Evaluate Actel SmartFusion or IGLOO2 devices for modern low-power alternatives with comparable I/O counts.
