5SGXEA5N3F45I3LG

Overview

The Altera 5SGXEA5N3F45I3LG is a Stratix V GX Field Programmable Gate Array (FPGA) designed for high-performance digital signal processing and networking applications. It features 2640 Logic Array Blocks (LABs), providing substantial programmable logic capacity. The device integrates 37 Mbits of embedded memory, including SRAM blocks, to support complex data buffering and storage requirements. It includes 36 transceivers capable of operating at data rates up to 14.1 Gb/s, facilitating high-speed serial communications. The component operates within an industrial temperature range of -40°C to +85°C and utilizes a 1152-ball FBGA package.

Feature Summary

• High-density logic fabric with 2640 LABs for complex algorithm implementation
• Integrated high-speed transceivers supporting multi-gigabit serial interfaces
• Substantial embedded memory resources for on-chip data handling
• Industrial-grade thermal performance for reliable operation in demanding environments

Applications

• High-speed telecommunications infrastructure equipment
• Digital signal processing systems requiring parallel computation
• Network switching and routing hardware
• Test and measurement instrumentation

Procurement Notes

Verify the exact suffix configuration against official Altera documentation, as ordering codes may include specific packaging or environmental qualifiers. Confirm current lifecycle status, as older Stratix V models may be subject to end-of-life notices. Ensure compatibility with required Quartus Prime software versions for compilation and programming. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Compare the 2640 LAB count and 36 transceiver availability against project requirements to ensure sufficient resource headroom. Evaluate the 14.1 Gb/s transceiver speed against target interface standards such as SFP+ or XAUI. Consider the 1152-ball FBGA package constraints for PCB layout and thermal management design. Assess power consumption profiles relative to available cooling solutions.

Part Context

This component belongs to the Stratix V GX family, which emphasizes high-speed serial connectivity alongside robust logic capabilities. It serves as a mid-range solution within the Stratix V portfolio, balancing performance with power efficiency. The device supports advanced DSP features and hard processor system integration options in larger variants, though this specific model focuses on pure FPGA fabric and transceiver performance.

Replacement Considerations

Direct pin-to-pin replacements are generally not available due to architectural differences between FPGA families. Consider migrating to Agilex series devices for improved performance and lower power consumption, though this requires significant schematic and firmware redesign. Consult Altera for obsolescence management programs if continuing production with legacy Stratix V parts.
