1SX250LU3F50I3XG

Overview

The Altera 1SX250LU3F50I3XG is a Stratix 10 SX System on Chip FPGA featuring an embedded quad-core ARM Cortex-A53 processor with CoreSight debug support. It provides 2,500K logic elements and integrates 256KB of RAM within the SoC architecture. The device operates at speeds up to 1.5GHz and supports standard peripherals including Ethernet, USB OTG, I2C, SPI, UART/USART, MMC/SD/SDIO, and EBI/EMI interfaces. It utilizes a 2912-pin FCBGA package measuring 55x55mm, designed for high-density applications requiring combined processing and programmable logic capabilities.

Feature Summary

• Integrates a quad-core ARM Cortex-A53 MPCore processor with CoreSight technology for embedded control tasks alongside FPGA fabric
• Combines 2500K logic elements with significant embedded memory resources for complex data path acceleration
• Supports high-speed serial connectivity through integrated transceivers capable of 28.3 Gb/s data rates
• Includes comprehensive peripheral interfaces such as Ethernet, USB OTG, and standard serial buses for system integration

Applications

• Baseband processing in telecommunications infrastructure equipment
• High-performance industrial automation controllers requiring real-time deterministic logic
• Medical imaging systems needing parallel signal processing and embedded control
• Automotive infotainment and advanced driver assistance systems (ADAS) front-ends

Procurement Notes

Verify the specific suffix codes against the official Intel/Altera datasheet to ensure correct temperature grade, package variant, and manufacturing revision. Confirm that the required software tools, such as Quartus Prime Pro Edition, are compatible with the selected device version before finalizing procurement orders to avoid integration delays.

Selection Notes

Select this model when a design requires both high-level application processing via ARM cores and hardware acceleration via FPGA logic. Compare against the GX series if high-speed transceiver count is the primary constraint rather than logic density. Ensure the PCB layout supports the 55x55mm BGA footprint and thermal requirements for the 100°C junction temperature rating.

Part Context

This component belongs to the Stratix 10 SX family, which targets cost-sensitive applications compared to the GX series while maintaining full SoC functionality. It shares the same foundational silicon architecture but may differ in transceiver counts and specific I/O configurations. It serves as a bridge between traditional microcontrollers and high-end FPGAs for mixed-signal and control-heavy designs.

Replacement Considerations

Direct pin-to-pin replacements within the Stratix 10 SX family include 1SX250HU3F50I3XG or 1SX250HH3F55E3XG, subject to verification of package dimensions and speed grades. Cross-family migration to Agilex devices requires significant architectural redesign and is not a direct substitute.
