A54SX72A-2PQG208I

Overview

The A54SX72A-2PQG208I is an antifuse-based Field Programmable Gate Array (FPGA) from the Actel SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 dedicated flip-flops within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 360 user-programmable I/Os and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It delivers 250 MHz system performance and 350 MHz internal clock frequencies. The -2 speed grade indicates approximately 25% faster performance than the standard grade. It includes four quadrant clocks and supports IEEE 1149.1 boundary-scan testing.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated security features including FuseLock technology to prevent reverse engineering

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems utilizing mixed-voltage I/O standards
• Secure hardware implementations protecting intellectual property via antifuse technology
• PCI-compliant interfaces supporting 3.3 V and 5 V signaling

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to discontinued status. Confirm RoHS compliance markings on packaging. Check for moisture sensitivity level 3 handling requirements during storage and reflow soldering processes. Ensure design files are compatible with legacy Actel Designer software versions.

Selection Notes

Select this model for designs requiring high gate density with nonvolatile configuration. Compare against A54SX32A if lower resource utilization suffices. Consider the -2 speed grade for applications needing improved timing margins over standard grades. Verify thermal dissipation capabilities within the PQFP208 package for intended operating conditions.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series was designed to replace complex CPLDs and gate arrays in high-performance applications. Microchip Technology acquired Actel, integrating these devices into their broader FPGA portfolio.

Replacement Considerations

Publicly confirmed direct substitutes include other speed grades within the A54SX72A series such as A54SX72A-1PQG208I or A54SX72A-PQG208I. Alternative packages like CQ208 or TQ144 may be considered if pinout compatibility allows. No cross-family replacements are officially documented.
