A54SX16A-PQG208

Overview

The A54SX16A-PQG208 is a 24,000 system gate FPGA from the Actel SX-A family, fabricated on 0.22 μm/0.25 μm CMOS antifuse technology. It features 175 user-programmable I/Os in a 208-pin PQFP package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It delivers up to 250 MHz system performance and 350 MHz internal clock speeds. The architecture includes three global clocks (HCLK, CLKA, CLKB) and dedicated flip-flops for deterministic timing.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Configurable I/O support for multiple standards including 3.3 V/5 V PCI, 5 V TTL, and 3.3 V LVTTL
• FuseLock security technology prevents reverse engineering and unauthorized design access

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays
• Systems requiring hot-swappable interface capabilities
• Applications needing secure, nonvolatile configuration without external bitstream storage
• Mixed-voltage digital interfaces supporting 5 V drive strength and tolerance

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm RoHS compliance status and packaging specifications against current datasheet revisions. Check for discontinuance notifications as older speed grades may be phased out. Ensure proper ESD handling procedures are followed during receipt and storage due to humidity sensitivity classification.

Selection Notes

Select this part for designs requiring 24,000 system gates with high-speed antifuse programming. Choose the PQG suffix for 208-pin Plastic Quad Flat Pack housing. Verify temperature grade requirements match the specific application environment. Consider pin count limitations relative to the 175 available user I/Os when mapping system interfaces.

Part Context

This component belongs to the Actel SX-A family of FPGAs, now managed by Microchip Technology following acquisition. The SX-A series utilizes antifuse technology for permanent, low-impedance interconnections. This specific model represents the mid-range capacity device within the family, offering a balance between logic density and I/O availability for general-purpose programmable logic applications.

Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in public documentation. Evaluate higher-capacity SX-A models like the A54SX32A if additional resources are needed. Consider modern Microchip PolarFire or IGLOO families for updated process nodes and features while verifying interface compatibility.
