KSZ8563RNXI-TR

Controllers Overview

The KSZ8563RNXI-TR is a 3-port 10/100 Ethernet switch manufactured by Microchip Technology, housed in a 64-pin VQFN package. It integrates two 10BASE-T/100BASE-TX PHYs and one configurable MAC port supporting RGMII, MII, or RMII interfaces. The device operates within an industrial temperature range of -40°C to +85°C and supports data rates of 10 Mb/s and 100 Mb/s. Key specifications include IEEE 1588v2 PTP support, AVB capabilities, Energy-Efficient Ethernet (EEE), Wake-on-LAN, and QoS features.

Controllers Feature Summary

• Non-blocking wire-speed switching fabric with hardware timestamping for IEEE 1588v2 Precision Time Protocol.
• Integrated management features including VLAN support, Access Control List filtering, and Rapid Spanning Tree Protocol.
• Flexible host interface options via SPI, I2C, MIIM, and in-band management through any data port.

Controllers Applications

• Automotive Ethernet systems
• Industrial Ethernet networks such as Profinet, MODBUS, and Ethernet/IP
• Real-time Ethernet control and automation switches

Controllers Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) against the extended range variant. Confirm the 'TR' suffix indicates tape and reel packaging. Ensure compatibility with the required voltage levels for the RGMII/MII/RMII host interface before finalizing orders.

Controllers Selection Notes

Select this component when a compact 3-port solution with integrated PHYs and precise time synchronization is required. Compare against the NXV suffix if operation up to +105°C is necessary. Consider the KSZ8567RTXI-TR if additional ports or managed switching features are needed for larger network topologies.

Controllers Part Context

This part belongs to the KSZ8563R series of high-performance Ethernet switches. It is designed to offload host processing tasks through dedicated hardware for forwarding, filtering, and time stamping. The series targets applications requiring deterministic latency and robust network management in constrained environments.

Controllers Replacement Considerations

KSZ8563RNXV-TR serves as the extended temperature alternative. For higher port counts, the KSZ8567RTXI-TR provides a 7-port managed switch option within the same ecosystem.
