A54SX08-TQG176

Overview

The Microsemi A54SX08-TQG176 is a Field Programmable Gate Array (FPGA) belonging to the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and 768 logic modules, comprising 512 combinatorial cells and 256 dedicated flip-flops. The device supports up to 130 user-programmable I/O pins and features three global clock networks. It operates within a voltage range of 2.25 V to 5.25 V and supports mixed-voltage operation with 5 V input tolerance. The component is housed in a 176-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.
• Includes Boundary-Scan Testing capabilities compliant with IEEE Standard 1149.1 for diagnostic verification.

Applications

• Low-power, high-performance embedded logic designs
• Systems requiring deterministic timing and pin-locking
• Applications needing secure, nonvolatile single-chip FPGA solutions

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm that the TQG176 designation corresponds to the correct 176-pin Thin Quad Flat Pack variant. Ensure compatibility with existing board layouts regarding pin assignments and thermal characteristics before procurement.

Selection Notes

Select this model when 12,000 system gates and 130 I/Os are sufficient for the design. Consider the -1 or -2 speed grades if higher internal performance than standard is required. Verify that the 176-pin TQFP package fits the mechanical constraints and that the operating temperature range meets the application environment.

Part Context

This component is part of the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers a sea-of-modules architecture with DirectConnect and FastConnect routing resources for optimal silicon utilization and predictable timing.

Replacement Considerations

Check for other speed grades within the A54SX08A series, such as A54SX08A-1TQG176 or A54SX08A-2TQG176, if performance adjustments are needed. Other packages like PQFP208 or FBGA variants may be available but require schematic and layout modifications.
