1SX065HH3F35I2LG

Overview

The Altera 1SX065HH3F35I2LG is a Stratix 10 SX System-on-Chip FPGA featuring an embedded quad-core ARM Cortex-A53 processor with CoreSight debug infrastructure. It integrates 650K logic elements and provides 392 I/O pins within a 1152-ball FCBGA package measuring 35x35 mm. The device operates at speeds up to 1.5 GHz and includes 256 KB of embedded RAM. It supports industrial temperature ranges from -40°C to 100°C junction temperature, offering integrated connectivity via Ethernet, USB OTG, SPI, and UART interfaces for high-performance computing applications.

Feature Summary

• Integrates a quad-core ARM Cortex-A53 MPCore processor with NEON and floating-point units for embedded control tasks
• Combines 650K FPGA logic elements with on-processor memory for flexible hardware acceleration
• Supports multiple high-speed peripheral interfaces including Ethernet, USB OTG, and standard serial protocols

Applications

• Industrial automation controllers requiring real-time processing and programmable logic
• Telecommunications baseband processing units
• Medical imaging system front-ends
• Automotive infotainment and instrument clusters

Procurement Notes

Verify the specific suffix codes against official Intel/Altera documentation to confirm temperature grade and package variant accuracy. Confirm current production status and lead times directly with authorized distributors as supply chain conditions fluctuate. Ensure ESD handling procedures are followed during installation due to the fine-pitch BGA packaging.

Selection Notes

Select this model when a combined ARM processor and FPGA fabric is required within a compact 35x35 mm footprint. Compare against the 1SG series if high-speed transceivers are needed instead of embedded processing. Verify that the 650K logic element count meets design complexity requirements before finalizing the part number choice.

Part Context

This component belongs to the Stratix 10 SX family, which targets cost-sensitive embedded applications compared to the GX series. It shares the same architectural foundation but omits high-speed transceivers in favor of integrated ARM processors. This positioning makes it suitable for applications prioritizing compute density over extreme data throughput.

Replacement Considerations

Direct pin-to-pin replacements within the same package are limited within the Stratix 10 SX lineup. Consider the 1SX065HH3F35E2LG for commercial temperature variants or other 1SX065 derivatives if logic capacity matches. Cross-family migration to Arria 10 requires significant schematic and software redesign.
