A54SX08-1PLG84

Overview

The Microsemi A54SX08-1PLG84 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It features a Plastic Quad Flat Pack (PQFP) package with 84 pins, providing up to 69 user-programmable I/Os. The device contains 768 logic modules and supports system performance of 250 MHz with internal clock frequencies reaching 350 MHz. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 0.22 μm / 0.25 μm CMOS process technology.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Includes Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for diagnostic and verification capabilities.

Applications

• Low-power, high-performance designs requiring deterministic timing
• Systems needing 66 MHz PCI compliance
• Applications requiring hardware security against reverse engineering

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'P' indicates a PQFP package, while 'L' denotes lead-free packaging. Confirm that the '-1' speed grade meets the required system performance specifications for your design implementation.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate configuration bitstreams. Ensure the design fits within the 768 logic module capacity and verify that the 84-pin PQFP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated on a high-voltage twin-well CMOS process. The SX-A series provides a cost-effective alternative to SRAM-based FPGAs by offering inherent security and zero standby power due to its antifuse technology.
