A54SX08-PLG84I

Overview

The Microsemi A54SX08-PLG84I is an SX-A series Field Programmable Gate Array (FPGA) utilizing antifuse technology. It provides 12,000 system gates and 768 logic modules. The device supports up to 130 user-programmable I/O pins and operates within a voltage range of 2.25V to 5.25V. It features three global clock networks and complies with IEEE 1149.1 for boundary-scan testing. The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• Integration of 66 MHz PCI compliant designs
• High-performance state machines and fast counters
• Secure single-chip nonvolatile solutions

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm that the PLG84I designation corresponds to the intended Industrial temperature range and PQFP package type. Ensure compatibility with existing board layouts regarding pin assignments and thermal characteristics before finalizing procurement orders.

Selection Notes

Select this model when designing for environments requiring robust anti-fuse reliability and secure programming capabilities. Consider the 208-pin PQFP package constraints for PCB space. Evaluate the 12,000 gate capacity against logic complexity requirements. Verify that the 130 available I/Os meet interface needs for the target application architecture.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed to replace multiple CPLDs or gate arrays by offering high performance and low power consumption in a single-chip solution. The A54SX08 variant represents the entry-level capacity within this specific product line.
