A54SX32-2TQG176

Overview

The A54SX32-2TQG176 is a Field Programmable Gate Array from the Actel SX-A family, featuring 48,000 system gates and 2,880 configurable logic blocks. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide deterministic timing and high performance with internal clock frequencies up to 350 MHz. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package and includes features such as hot-swap compliant I/Os, boundary scan testing via IEEE 1149.1 JTAG, and secure programming through FuseLock technology.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Includes nonvolatile antifuse architecture with FuseLock security to prevent reverse engineering and design theft
• Provides deterministic user-controllable timing with 100% resource utilization and pin locking capabilities

Applications

• 66 MHz PCI compliant single-chip solutions integrating CPLD and FPGA functionality
• High-performance designs requiring low power consumption and fast execution of complex logic functions
• Applications necessitating hot-swappable interfaces and cold-sparing capabilities

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required performance level, as it indicates approximately 25% faster operation than standard speed. Confirm the temperature grade 'G' aligns with commercial operating conditions. Ensure the TQFP package type matches the PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this device when a nonvolatile FPGA solution with high performance and security is required. The SX-A family is suitable for designs needing deterministic timing and mixed-voltage I/O support. Consider the 176-pin TQFP package for applications where surface mount thin profiles are preferred. Evaluate the 48,000 system gate capacity against design complexity to ensure sufficient logic resources and I/O availability.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32 variant specifically offers 48,000 system gates and 2,880 CLBs. The SX-A series is known for its sea-of-modules architecture and patented metal-to-metal programmable interconnect elements.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A in TQFP176, such as A54SX32-1TQG176 or A54SX32-TQG176. Devices from the original SX family may be compatible but require verification of electrical specifications and timing characteristics.
