A54SX16A-PQ208M

Overview

The A54SX16A-PQ208M is a nonvolatile Field Programmable Gate Array (FPGA) from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and supports up to 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP). The device operates with supply voltages of 2.5 V, 3.3 V, or 5 V, featuring mixed-voltage operation with 5 V input tolerance. It delivers 250 MHz system performance and 350 MHz internal clock speeds, utilizing dedicated flip-flops and combinatorial cells for high-density logic implementation.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing through unique local routing resources including DirectConnect and FastConnect for minimal signal propagation delays.
• Integrated security features via FuseLock technology to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration replacing complex programmable logic devices (CPLDs)
• PCI-compliant interface designs supporting 66 MHz bus operations
• Systems requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify the specific ordering suffix 'M' against manufacturer documentation to confirm military temperature grade availability (-55°C to +125°C). Confirm RoHS compliance status as standard packaging may differ from lead-free variants. Ensure the PQFP-208 package type matches the target PCB footprint specifications before procurement.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed internal routing is required. The A54SX16A offers 24,000 system gates suitable for moderate complexity designs. Verify that the 208-pin PQFP package fits the mechanical constraints and that the speed grade meets the 250 MHz system performance requirement.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse-based nonvolatile architecture. The SX-A series is designed for applications demanding low power consumption, high performance, and robust security features compared to volatile SRAM-based FPGAs.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A such as A54SX16A-1PQ208M or A54SX16A-2PQ208M. Cross-family replacements require verification of gate count and I/O compatibility.
