A54SX32A-2TQG176I

Overview

The A54SX32A-2TQG176I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 176-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 147 user-programmable I/O pins and includes three global clock networks. It is fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology, enabling deterministic timing and high-speed performance.

Feature Summary

• Supports hot-swap capabilities for most I/O standards, allowing safe insertion into active systems without power sequencing requirements.
• Provides nonvolatile configuration via metal-to-metal antifuse interconnects, ensuring permanent programming and inherent design security.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing with dedicated or flexible JTAG modes for in-system diagnostics.

Applications

• High-performance digital signal processing and control logic
• Interface bridging between legacy 5V and modern 3.3V/2.5V components
• Secure embedded systems requiring protection against reverse engineering

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required timing constraints for your design. Confirm that the TQFP-176 package dimensions align with your PCB footprint. Ensure the industrial temperature rating meets environmental specifications. Check current availability status as manufacturing lifecycles may vary.

Selection Notes

Select this part when 48K system gates and 147 I/Os are sufficient for the application. The -2 speed grade offers approximately 25% faster performance than standard grades. Consider the TQFP-176 package if leaded pin accessibility is preferred over BGA density. Verify mixed-voltage I/O requirements match the supported standards.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize antifuse technology for nonvolatile configuration. The SX-A series is designed for low-power, high-performance applications, offering deterministic timing through its unique routing architecture. Microchip Technology acquired Actel, continuing support for these devices.
