A54SX16P-PQ208

Overview

The A54SX16P-PQ208 is a nonvolatile Field Programmable Gate Array from the Actel 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 I/Os in a 208-pin PQFP package. The device operates with supply voltages of 2.5 V, 3.3 V, or 5 V, enabling mixed-voltage operation with 5 V input tolerance. It features hot-swap compliant I/Os, deterministic timing, and boundary-scan testing compliance with IEEE Standard 1149.1.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports mixed-voltage I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 with individually configurable slew rates.
• Hot-swap compliant architecture allows insertion into active systems without degrading host reliability, with I/Os tristating during power-up/down sequences.
• Includes dedicated clock networks (HCLK, CLKA, CLKB) and fast local routing resources (DirectConnect, FastConnect) for predictable signal propagation.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Systems requiring deterministic timing and 100% pin locking capabilities

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm that the ordering suffix matches the required speed grade and temperature range specifications. Ensure handling procedures account for moisture sensitivity levels as indicated in the datasheet. Validate RoHS compliance status against specific manufacturing lot requirements prior to procurement.

Selection Notes

Select this model when 24,000 system gates are sufficient for the design complexity. Choose the PQ208 package if surface-mount quad flat pack form factor is required. Verify that the standard speed grade meets the target system performance requirements. Consider the -F speed grade only if slower operation is specifically needed for timing closure.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were acquired by Microchip Technology. The SX-A series is characterized by its antifuse-based nonvolatile architecture, offering high reliability and security compared to SRAM-based FPGAs. It serves as a bridge between traditional CPLDs and larger FPGA solutions.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate newer Microchip FPGA families such as PolarFire or IGLOO for modern replacements, ensuring compatibility with existing PCB footprints and logical resource requirements.
