A54SX16P-1PQ208I

Overview

The A54SX16P-1PQ208I is a nonvolatile Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and features a sea-of-modules architecture with 768 logic modules comprising 512 combinatorial cells and 256 dedicated flip-flops. The device supports up to 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates at an industrial temperature range of -40°C to +85°C and achieves approximately 15% faster performance than standard speed grades.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through metal-to-metal programmable antifuse interconnect elements for low signal impedance.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for superior diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile configuration
• Systems demanding hot-swappable interface compatibility
• Industrial applications requiring operation across extended temperature ranges

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the ordering suffix matches the required speed grade and temperature rating. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific package variant aligns with PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this model when design capacity requires 24,000 system gates with high-speed performance exceeding standard grades. Consider the PQFP package constraints regarding pin count and thermal dissipation. Evaluate the need for industrial temperature stability and nonvolatile antifuse technology over volatile alternatives. Verify I/O voltage compatibility with existing system components during the selection process.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for permanent configuration. The SX-A series is designed for cost-effective, low-power, and high-performance applications. It serves as a single-chip solution integrating complex logic functions previously requiring multiple devices or gate arrays.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series such as A54SX16A-PQ208I or A54SX16A-2PQ208I. Cross-family migration may require significant redesign due to architectural differences between antifuse and SRAM-based FPGAs.
