SJA1105PELY

Controllers Overview

The SJA1105PELY is a five-port automotive Ethernet switch supporting IEEE AVB and TSN standards. It features individually configurable ports operating at 10/100 Mbit/s via MII/RMII or 10/100/1000 Mbit/s via RGMII/SGMII. The device supports independent I/O voltage domains of 1.8 V, 2.5 V, or 3.3 V with a 1.2 V core voltage. It provides hardware support for IEEE 802.1AS timestamping, IEEE 1588v2 one-step sync forwarding, and 4096 VLANs. Operating within an ambient temperature range of -40 °C to +105 °C, it utilizes an LFBGA159 package.

Controllers Feature Summary

• Supports deterministic network delays and bandwidth partitioning between critical and non-critical traffic
• Provides hardware-based synchronization and audio/video bridging capabilities
• Includes frame header security features for firewall applications and error prevention

Controllers Applications

• Modular Electronic Control Units (ECUs)
• Advanced Driving Assistance Systems (ADAS)
• Automotive gateway devices

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required interface configurations and voltage levels. Confirm that the component meets the necessary AEC-Q100 Grade 2 qualification requirements for the intended automotive application environment before finalizing procurement.

Controllers Selection Notes

Select this component when designing systems requiring deterministic Ethernet performance with integrated AVB and TSN support. Ensure the design accommodates the LFBGA159 package footprint and verifies compatibility with the required host processor interfaces, such as SPI for configuration access. Validate that the available port configurations align with the specific PHY requirements of the target application.

Controllers Part Context

This part belongs to the SJA1105P/Q/R/S series of automotive-grade Ethernet switches. The 'P' designation indicates a version without SGMII interface options, distinguishing it from other variants in the family. It serves as a foundational switching solution for modern vehicle architectures requiring high-speed, synchronized data transmission across multiple electronic control units.

Controllers Replacement Considerations

The SJA1105QEL, SJA1105REL, and SJA1105SEL are pin-compatible alternatives within the same package. Verify if the additional interface capabilities of these variants are required or if their specific feature sets align better with the system design constraints.
