LAN9384-I/6XX

Controllers Overview

The LAN9384-I/6XX is a 7-port AVB/TSN Gigabit Ethernet switch featuring five integrated 100BASE-T1 PHYs and one 100BASE-TX port. It includes an ARM Cortex-M7 CPU subsystem operating at 300MHz with 2MB flash, 64KB ROM, and 768KB RAM. The device supports up to one SGMII port and operates within the -40°C to +105°C automotive temperature range in a 128-pin TQFP package.

Controllers Feature Summary

• Integrated hardware security engine supporting SHA-256/512, ECDSA, and AES encryption for secure boot and data protection.
• Full support for Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards including IEEE 1588v2 PTP synchronization.
• Advanced diagnostics capabilities including LinkMD+ cable testing and Signal Quality Indicator monitoring for T1 ports.

Controllers Applications

• Automotive gateways
• In-vehicle backbone networks
• Advanced Driver-Assistance Systems (ADAS)
• Infotainment systems

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's Product Identification System to confirm packaging options such as tape and reel availability. Ensure the selected variant matches the required Grade 2 Automotive temperature range specifications before finalizing procurement orders.

Controllers Selection Notes

Select this model when five 100BASE-T1 ports are required alongside a legacy 100BASE-TX interface. The integrated CPU and memory reduce external component count compared to standard switches. Verify that the single available MAC port configuration meets system connectivity requirements.

Controllers Part Context

This component belongs to the LAN938x family of scalable Ethernet switches designed for automotive environments. It shares the same core architecture and package type as the LAN9381, LAN9382, and LAN9383 models, differing primarily in the number of integrated T1 PHYs and presence of the TX port.

Controllers Replacement Considerations

The LAN9382 serves as a functional alternative if four T1 ports and one TX port suffice. The LAN9383 provides five T1 ports but lacks the TX interface. Cross-referencing port counts and interface types is essential for direct substitution.
