A54SX08-FGG144

Overview

The A54SX08-FGG144 is a Field Programmable Gate Array from the SX-A family, featuring 12,000 system gates and 768 logic modules. It operates with a maximum system frequency of 250 MHz and an internal performance of 350 MHz. The device supports up to 111 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The component is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without power sequencing requirements
• Deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Systems requiring deterministic timing and pin-locking capabilities for concurrent PCB development
• Applications necessitating secure programming to prevent reverse engineering via FuseLock technology

Procurement Notes

Verify the specific speed grade suffix associated with the -FGG144 package designation, as standard speed variants exist alongside faster grades within the SX-A family. Confirm that the commercial temperature range aligns with operational requirements. Ensure compatibility with Actel Designer software versions supporting the SX-A architecture for accurate place-and-route implementation.

Selection Notes

Select this model when 12,000 system gates and 111 user I/Os are sufficient for the design complexity. Consider the FBGA package for high-density board layouts. Evaluate the 250 MHz system performance against timing constraints. Verify that the 0.22/0.25 μm process technology meets the required power consumption and voltage tolerance specifications for the target application environment.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their nonvolatile antifuse technology. The family ranges from 12,000 to 108,000 system gates, offering scalable logic density. The SX-A series is designed for low-power, high-performance applications, providing a cost-effective alternative to volatile FPGA solutions while maintaining robust security features against unauthorized access.

Replacement Considerations

Direct functional replacements within the same package and pinout include other speed grades of the A54SX08A series, such as the A54SX08-1FGG144 or A54SX08-2FGG144, provided timing requirements allow for slower performance. Cross-family migration to ProASIC3 or IGLOO devices requires schematic redesign due to architectural differences.
