A54SX08A-PQG208

Overview

The Microsemi A54SX08A-PQG208 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It provides 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 features up to 130 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability or requiring specific power sequencing.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources to minimize signal propagation delays.

Applications

• High-performance digital logic integration replacing complex CPLDs
• Industrial control systems requiring hot-swappable interface capabilities
• Secure embedded designs utilizing FuseLock anti-tamper protection

Procurement Notes

Verify the ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix indicates RoHS-compliant packaging if environmental compliance is required. Ensure the PQFP-208 package matches the target PCB footprint specifications.

Selection Notes

Select this component when nonvolatile configuration and deterministic performance are critical. The SX-A architecture offers high resource utilization and pin-locking capabilities. Consider the 12,000 gate capacity and 130 I/O limit against design requirements before choosing larger devices in the A54SX series.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which were acquired by Microsemi Corporation. The SX-A line utilizes antifuse technology rather than SRAM, providing inherent security and zero standby power. This specific model represents the mid-range density option within the 208-pin package lineup.

Replacement Considerations

Direct replacements include other speed grades of the A54SX08A such as A54SX08A-1PQG208 or A54SX08A-2PQG208 for higher performance. Cross-family migration to ProASIC3 or Fusion requires significant architectural redesign due to differences in logic structure and programming technology.
