KSZ8462HLI

Controllers Overview

The KSZ8462HLI is a two-port, 10/100 Mbps Ethernet switch with IEEE 1588v2 Precision Time Protocol support. It features an integrated non-blocking store-and-forward switching fabric and two 10BASE-T/100BASE-TX PHY transceivers. The device includes three internal MAC units, one of which serves as a host interface via a selectable 8- or 16-bit parallel bus. Key specifications include a 32Kbyte frame buffer, 1024-entry forwarding table, and single 3.3V power supply operation. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 64-pin LQFP package.

Controllers Feature Summary

• Supports IEEE 1588v2 Transparent Clock modes for sub-microsecond synchronization
• Integrates Energy Efficient Ethernet (EEE) capabilities for reduced power consumption
• Provides flexible management through configurable GPIO pins and LED indicators
• Includes comprehensive Quality of Service (QoS) and VLAN tagging features

Controllers Applications

• Industrial Ethernet networks requiring precise time synchronization
• IEC 61850 power substation automation systems
• Real-time motion control and measurement equipment

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to ensure correct pinout and feature configuration. Confirm that the required voltage levels for VDD_IO match the target system design. Check for any applicable errata sheets related to the silicon revision before finalizing procurement plans.

Controllers Selection Notes

Select this component when a two-port solution with hardware-based timestamping is required. Ensure the host processor supports the necessary 8- or 16-bit parallel interface timing. Consider the KSZ8462FHLI variant if fiber optic connectivity is needed instead of copper-only ports.

Controllers Part Context

This part belongs to the KSZ8462 EtherSynch product line designed for industrial applications. It complements other switches in the family by offering a compact two-port form factor with robust synchronization features suitable for daisy-chained network topologies.

Controllers Replacement Considerations

Consult Microchip documentation for direct substitutes within the KSZ84xx family. Verify compatibility regarding package dimensions and register mapping if replacing with variants like the KSZ8463 series.
