A54SX32A-TQG176

Overview

The A54SX32A-TQG176 is a 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 2,880 configurable logic blocks (CLBs). The device supports up to 249 user-programmable I/O pins within a 176-pin Thin Quad Flat Pack (TQFP) package. It features internal performance of 350 MHz and system performance of 250 MHz. The architecture includes three global clock networks and dedicated routing resources like DirectConnect and FastConnect for deterministic timing.

Feature Summary

• Supports mixed-voltage operation with 2.5 V, 3.3 V, and 5 V I/O standards including PCI, TTL, LVTTL, and LVCMOS2.
• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital logic integration
• PCI-compliant interface designs
• Systems requiring deterministic timing and pin locking

Procurement Notes

Verify the specific speed grade suffix associated with the TQG176 package variant. Confirm temperature range availability as commercial, industrial, or military grades may have distinct ordering codes. Ensure design tools support the SX-A antifuse programming flow.

Selection Notes

Select this model for applications requiring high-density logic in a QFP package. Compare against other SX-A devices based on required I/O count and gate capacity. Verify that the 176-pin footprint meets PCB layout constraints. Check if the standard speed grade meets timing requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes nonvolatile antifuse technology. The family ranges from 12,000 to 108,000 system gates. The SX-A series is known for its sea-of-modules architecture and metal-to-metal interconnects, offering high performance and security compared to volatile FPGA alternatives.

Replacement Considerations

Check for updated Microchip versions of the SX-A family. Verify pin compatibility if substituting with other TQFP packages in the same gate density class. Ensure software toolchains are compatible with the target replacement part.
