A54SX08-PL84I

Overview

The A54SX08-PL84I is a nonvolatile FPGA from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. The device features up to 360 user-programmable I/O pins, dedicated flip-flops, and global clock networks including HCLK, CLKA, and CLKB. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down in any order without supply voltage sequencing requirements.
• Includes configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.
• Features boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for superior diagnostic and verification capabilities.

Applications

• High-performance logic integration requiring deterministic timing and fast execution of complex functions.
• Systems requiring mixed-voltage I/O standards such as 3.3 V PCI, 5 V TTL, and 2.5 V LVCMOS2.
• Applications necessitating secure programming and protection against reverse engineering via FuseLock technology.

Procurement Notes

Verify the specific package type associated with the PL84 suffix, as standard datasheets list PQFP, TQFP, PBGA, FBGA, and CQFP options. Confirm that the Industrial temperature grade (-40°C to +85°C) matches the 'I' designation if present in the full part number. Ensure the design tool suite supports the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed internal performance up to 350 MHz is required. Consider the 12,000 system gate capacity and the availability of DirectConnect and FastConnect routing resources for optimal register/logic mix. Verify that the available I/O standards and voltage levels align with the system interface requirements.

Part Context

This model belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, and high-performance applications. The family utilizes antifuse technology to provide a versatile platform for integrating designs previously contained in multiple CPLDs or gate arrays, significantly reducing time-to-market.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other devices within the SX-A family based on gate count and pin compatibility, or consult manufacturer resources for modern equivalents.
