A54SX08-PL84

Overview

The A54SX08-PL84 is a Field Programmable Gate Array from the Microsemi SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 typical system gates and 768 logic modules (CLBs). The device supports up to 360 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It features three global clock networks and operates with mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. The architecture utilizes metal-to-metal programmable antifuses for permanent interconnection.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal antifuse technology for deterministic timing and high performance.
• Supports hot-swap capabilities and power-up/down friendly operation without requiring supply voltage sequencing.
• Includes configurable I/Os supporting multiple voltage standards such as 3.3 V/5 V PCI, 5 V TTL, and 3.3 V LVTTL.
• Features Actel FuseLock security technology to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital signal processing systems
• PCI-compliant interface controllers
• State machine implementations requiring deterministic timing
• Secure embedded logic designs

Procurement Notes

Verify the specific speed grade suffix associated with the PL84 package, as standard speed variants are available. Confirm that the ordering suffix aligns with the required temperature range and RoHS compliance status. Ensure compatibility with Actel Designer software versions supporting the SX-A family for programming and verification.

Selection Notes

Select this device when 12,000 system gates and 768 CLBs are sufficient for the target logic density. Consider the PL84 package only if the pin count meets the I/O requirements. Evaluate the need for mixed-voltage I/O support and hot-swap functionality during the initial design phase to ensure proper board layout and power sequencing.

Part Context

This component belongs to the SX-A family of FPGAs, which offers a cost-effective alternative to gate arrays and CPLDs. The family ranges from 12,000 to 108,000 system gates, providing scalable solutions for various complexity levels. The SX-A series is known for its high-speed internal performance and robust security features inherent to antifuse technology.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX08A device, such as A54SX08A-1 or A54SX08A-2, provided the timing requirements are met. Cross-family migration to newer Microsemi FPGA architectures may require significant redesign due to differences in architecture and toolchains.
