A54SX08-PQG208

Overview

The A54SX08-PQG208 is a nonvolatile, single-chip Field Programmable Gate Array (FPGA) from the Microsemi SX-A family. It features 12,000 system gates and 768 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide deterministic timing and high performance.

Feature Summary

• Nonvolatile antifuse architecture eliminates configuration bitstreams and prevents reverse engineering via FuseLock security.
• Hot-swap compliant I/Os allow insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing achieved through patented metal-to-metal interconnects and DirectConnect routing resources.

Applications

• High-performance digital logic integration replacing complex CPLDs
• PCI-compliant interface designs requiring 66 MHz support
• Secure embedded control applications utilizing nonvolatile storage

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm that the component matches the required speed grade for the target application timing constraints. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture.

Selection Notes

Select this model when a nonvolatile FPGA solution with mixed-voltage I/O flexibility is required. The PQFP-208 package suits surface-mount designs needing moderate pin counts. Consider the standard speed grade if maximum frequency requirements align with baseline SX-A specifications.

Part Context

This component belongs to the SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS process technology. The family includes devices ranging from 12,000 to 108,000 system gates, offering various package options including PQFP, TQFP, and BGA types.

Replacement Considerations

Compatible substitutes include other members of the SX-A family such as the A54SX16A or A54SX32A in equivalent packages. Verify pinout compatibility and resource utilization before substitution.
