1SX085HN1F43I2LG

Overview

The Altera 1SX085HN1F43I2LG is a Stratix 10 SX System on Chip FPGA featuring an embedded ARM Cortex-A53 processor. It provides 850,000 logic elements and 284,960 Adaptive Logic Modules within a 1760-ball FCBGA package measuring 42.5x42.5 mm. The device includes 68 Mbit of embedded memory, 688 I/O pins, and 48 transceivers. It operates at a maximum speed of 1.5 GHz with a core voltage of 940 mV. The component supports industrial temperature ranges from -40°C to +100°C junction temperature.

Feature Summary

• Integrates a quad-core ARM Cortex-A53 MPCore processor with CoreSight debug infrastructure for hard processing system capabilities.
• Combines high-density FPGA fabric with embedded memory blocks and dedicated DSP slices for complex signal processing.
• Supports high-speed serial connectivity through multiple transceiver interfaces compatible with standard protocols.

Applications

• Telecommunications baseband processing and radio access network equipment
• Industrial automation controllers requiring real-time deterministic logic
• Medical imaging systems utilizing high-bandwidth data acquisition

Procurement Notes

Verify the specific suffix code against official Intel/Altera documentation to confirm temperature grade and packaging details. Ensure compatibility with Quartus Prime software versions supporting the Stratix 10 SX family. Confirm moisture sensitivity level handling requirements during assembly to prevent package damage.

Selection Notes

Select this model when a balance of moderate FPGA density and integrated ARM processing is required. Compare pin counts and transceiver speeds against higher-density Stratix 10 variants if more logic resources are needed. Verify that the 1760-ball package footprint fits the target PCB design constraints.

Part Context

This component belongs to the Stratix 10 SX family, designed for cost-sensitive applications requiring SoC integration. It sits below the GX and MX families in terms of transceiver count but offers significant processing power via the embedded ARM cores. The part represents a mid-range solution for scalable embedded systems.

Replacement Considerations

Direct replacements include other Stratix 10 SX parts with identical pinouts such as 1SX085HN2F43I2LG or 1SX085HN3F43E2VG, provided temperature grades match. Cross-family migration to Agilex devices requires significant redesign due to architectural differences.
