KSZ8463FRLI

Controllers Overview

The KSZ8463FRLI is a three-port managed Ethernet switch IC from Microchip Technology, designed for industrial applications requiring IEEE 1588v2 Precision Time Protocol synchronization. It integrates two 10/100BASE-TX copper transceivers and one 100BASE-FX fiber transceiver, alongside three MAC units and a non-blocking store-and-forward switch fabric with a 1K entry forwarding table. The device supports Reduced Media Independent Interface (RMII) on the third port and operates within an industrial temperature range of -40°C to +85°C. Power consumption is maintained below 0.5W, utilizing a single 3.3V supply with an internal low-voltage regulator.

Controllers Feature Summary

• Supports IEEE 1588v2 Precision Time Protocol with hardware-based time-stamping and transparent clock capabilities for sub-microsecond synchronization.
• Integrates mixed-media connectivity with two copper PHY ports and one fiber optic port, featuring HP Auto MDI/MDI-X support.
• Provides comprehensive Layer 2 management features including VLAN tagging, QoS prioritization, and Rapid Spanning Tree Protocol.
• Includes extensive GPIO resources synchronized to the precision time clock for flexible system control and event monitoring.

Controllers Applications

• Industrial Ethernet networks requiring sub-microsecond synchronization, such as EtherNet/IP and PROFINET.
• IEC 61850 power substation automation systems demanding high reliability and precise timing.
• Real-time motion control and automated manufacturing systems.
• Networked measurement and test equipment requiring accurate data timestamping.

Controllers Procurement Notes

Verify that the specific ordering suffix 'FRLI' corresponds to the RMII interface configuration combined with fiber port support and industrial temperature rating. Confirm package details match the 64-pin LQFP specification. Ensure compatibility with the required 25 MHz or 50 MHz reference clock input depending on the host interface design. Check for any specific errata sheets relevant to the silicon revision before finalizing procurement.

Controllers Selection Notes

Select the KSZ8463FRLI when both fiber optic connectivity and reduced pin-count host interfaces are required. This model is appropriate for designs needing IEEE 1588v2 synchronization without the complexity of external PHYs. Consider the KSZ8463MLI variant if MII interface is preferred over RMII, or the KSZ8463FMLI if MII is required with fiber support. Evaluate power budget constraints against the sub-0.5W typical dissipation.

Controllers Part Context

The KSZ8463FRLI belongs to the KSZ8463 EtherSynch product line, which focuses on integrated switching and synchronization for industrial environments. It complements other variants like the KSZ8463MLI and KSZ8463FMLI by offering a specific combination of interface type and media support. This family is designed to offload host processing through extensive filtering and QoS features.
