A54SX08-2PL84

Overview

The A54SX08-2PL84 is a field-programmable gate array from the Microsemi SX-A family, utilizing antifuse technology. It provides 12,000 typical 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 2.25V to 5.25V and is available in an industrial temperature grade (-40°C to +85°C). The -2 speed grade indicates approximately 25% faster performance than the standard speed variant.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Supports hot-swap capabilities and mixed-voltage operation with 5V input tolerance across multiple I/O standards.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• Industrial control systems requiring deterministic timing and high reliability.
• Military and aerospace applications necessitating radiation-hardened or high-reliability FPGA solutions.
• Automotive electronics designs compatible with mixed-voltage interfaces.

Procurement Notes

Verify the specific ordering suffix 'I' for industrial temperature range compliance when sourcing this component. Confirm package availability as PL84 may refer to a specific pin count variant not explicitly detailed in the primary datasheet table; cross-reference with official Microchip documentation to ensure correct physical dimensions and pinout compatibility for your PCB layout.

Selection Notes

Select the A54SX08-2PL84 when design requirements demand higher performance than the standard speed grade offers, specifically for applications needing approximately 25% faster logic propagation. Ensure the design utilizes the full 130 I/O capacity if maximum connectivity is required, and verify that the 768 CLB resource count suffices for the target logic complexity compared to larger devices like the A54SX16A.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, which are distinguished by their antifuse-based nonvolatile architecture. Unlike volatile SRAM-based FPGAs, these devices do not require a configuration bitstream at power-up, simplifying system design and enhancing security against data interception during boot sequences.

Replacement Considerations

For equivalent performance, consider the A54SX08-1PL84 for standard speed or A54SX08-FPL84 for slower speed grades. For increased capacity, the A54SX16A series offers double the system gates. Verify package compatibility if substituting with TQFP or BGA variants within the same logical family.
