A54SX72A-PQG208M

Overview

The A54SX72A-PQG208M is a nonvolatile Field Programmable Gate Array (FPGA) from the Actel SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and supports up to 360 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology, enabling internal clock frequencies of 350 MHz and system performance up to 250 MHz. It operates with supply voltages of 2.5 V, 3.3 V, or 5 V, supporting mixed-voltage operation with 5 V input tolerance.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap capabilities and power-up/down without voltage sequencing requirements, ensuring safe insertion into active systems.
• Includes dedicated global clock networks and quadrant clocks for deterministic timing and high-speed signal propagation.
• Compliant with IEEE Standard 1149.1 (JTAG) for boundary-scan testing and includes Actel Secure Programming Technology.

Applications

• High-performance digital logic integration requiring deterministic timing
• PCI-compliant interface designs operating at 66 MHz
• Systems requiring nonvolatile configuration without external memory

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status and check for end-of-life notifications, as older FPGA families may have limited availability. Ensure proper handling for moisture-sensitive devices according to industry standards.

Selection Notes

Select this model when 108,000 system gates and 208-pin PQFP packaging are required. Consider speed grades (-1, -2) if higher performance than standard is needed. Verify temperature grade suitability for the specific application environment.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance applications. The SX-A series offers a sea-of-modules architecture optimized for register/logic mix, providing flexibility for various digital design implementations.

Replacement Considerations

Check for discontinued speed grades (-3). Evaluate newer Microchip FPGA families for pin-compatible or functionally equivalent replacements if long-term supply is required.
