SJA1105SELY

Controllers Overview

The SJA1105SELY is a five-port automotive Ethernet switch from the NXP SJA1105P/Q/R/S family, designed for control applications. It supports IEEE 802.3 standards with individually configurable ports operating at 10/100 Mbit/s via MII/RMII or 10/100/1000 Mbit/s via RGMII/SGMII. The device features a store-and-forward architecture, hardware timestamping (IEEE 802.1AS), and AVB traffic shaping (IEEE 802.1Qav). It operates within an ambient temperature range of -40 °C to +105 °C, complies with AEC-Q100 Rev-H, and utilizes a 159-ball LFBGA package.

Controllers Feature Summary

• Supports deterministic network delays and jitter through strict bandwidth allocation between critical and non-critical traffic using Time-Sensitive Networking (TSN) capabilities.
• Enables fully synchronized networks via hardware support for IEEE 802.1AS timestamping and one-step sync forwarding.
• Provides flexible ECU design by supporting any 10/100/1000 BASE-TX PHYs with independent I/O voltage domains.

Controllers Applications

• Modular Electronic Control Units (ECUs) using Ethernet as the backbone
• Advanced Driving Assistance Systems (ADAS)
• Surround view camera integration

Controllers Procurement Notes

Verify the specific suffix 'S' against the official ordering table to confirm feature set alignment. Ensure the component meets the required Automotive Grade 2 qualification standards. Confirm that the LFBGA159 package dimensions match the target PCB layout constraints before finalizing procurement.

Controllers Selection Notes

Select this model when TSN features are required alongside standard AVB support. Verify interface compatibility with the host processor's SPI and MAC modes. Ensure power supply designs accommodate the specified 1.2 V core and selectable 1.8/2.5/3.3 V I/O domains for all connected peripherals.

Controllers Part Context

This component belongs to the SJA1105P/Q/R/S series, which extends the base SJA1105EL/TEL functionality with enhanced security features and expanded interface options. The 'S' variant specifically includes Time-Sensitive Networking (TSN) capabilities defined in IEEE standards, differentiating it from the AVB-only EL version.
