A54SX32-PQG208

Overview

The A54SX32-PQG208 is a nonvolatile Field Programmable Gate Array (FPGA) from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 249 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP). The device operates at commercial temperature grades with supply voltages ranging from 2.25 V to 5.25 V. It features deterministic timing performance with internal clock frequencies reaching 350 MHz and system performance of 250 MHz.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with configurable I/O standards including PCI, TTL, LVTTL, and LVCMOS2.
• Hot-swap compliant architecture allowing safe insertion into active systems without power sequencing requirements or system degradation.

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip Technology channels due to the discontinued status of the SX-A family. Confirm specific speed grade suffixes and temperature ratings against current inventory lists as availability varies by region. Ensure handling procedures account for moisture sensitivity levels defined in the datasheet.

Selection Notes

Select this model when 48,000 system gates and 208-pin PQFP packaging are required. Consider alternative speed grades if higher frequency performance than standard is needed. Verify that the 0.22/0.25 μm process technology aligns with legacy design constraints and that nonvolatile antifuse programming meets security requirements.

Part Context

This component belongs to the Actel SX-A FPGA family, which was acquired by Microchip Technology. The SX-A series is characterized by its high-density antifuse technology and robust I/O flexibility. It serves as a bridge between traditional gate arrays and modern volatile FPGAs, offering immediate power-up functionality without external configuration memory.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific obsolete model. Designers should evaluate newer Microchip PolarFire or IGLOO families for functional equivalents, noting differences in volatility and programming technology.
