A54SX32A-2PQ208I

Overview

The A54SX32A-2PQ208I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and 2,880 configurable logic blocks (CLBs). The device operates within a voltage range of 2.25 V to 2.75 V for core supply and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It utilizes a Plastic Quad Flat Pack (PQFP) package with 208 pins, providing up to 174 user I/Os. The -2 speed grade indicates approximately 25% faster performance than the standard grade, supporting internal clock frequencies up to 350 MHz. It is rated for industrial temperature operation from -40°C to +85°C.

Feature Summary

• Nonvolatile antifuse architecture provides permanent configuration without external memory or bitstream interception.
• Supports hot-swap capabilities allowing insertion into active systems without power sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high-speed interconnect.
• Integrates IEEE 1149.1 compliant Boundary-Scan Testing for enhanced diagnostic and verification capabilities.

Applications

• High-performance digital signal processing requiring low-latency logic execution
• Industrial control systems necessitating robust I/O flexibility and wide operating temperatures
• Prototyping complex gate array designs with immediate hardware availability

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature rating. Ensure compliance with export regulations such as EAR if applicable. Confirm that the component meets all environmental standards required for the target application before finalizing procurement.

Selection Notes

Select this model when a nonvolatile FPGA solution with mixed-voltage I/O support is required. The -2 speed grade offers higher performance than standard grades. Consider the 208-pin PQFP package constraints regarding board space and thermal dissipation. Verify that the 48,000 system gate capacity aligns with the design complexity.

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 family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32A variant specifically targets applications needing moderate logic density with high-speed performance characteristics.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as A54SX32A-PQ208I (Standard) or A54SX32A-1PQ208I (-1 Speed Grade). Cross-family migration may require schematic and layout modifications due to architectural differences.
