100Mbps industrial ethernet communication module reference design for multiprotocol applications

Overview

TopologyLAN / POE
IC revisionDecember 2025

Description

This reference design accelerates development of multiprotocol 100Mbps industrial Ethernet nodes. The design allows engineers to quickly prototype and deploy EtherCAT®, PROFINET®, EtherNet/IP, and Modbus® Transmission Control Protocol (TCP) on AM261x with Integrated Industrial Communication Subsystem (ICSS). The approach cuts hardware spins, simplifies clocking and power, and delivers deterministic, time-synchronized factory automation performance.

Features

Supports multiple industrial Ethernet protocols: EtherCAT®, PROFINET® Real-Time (RT) and Isochronous Real-Time (IRT), EtherNet/IP®, and Modbus® TCPICSS enabling software-selectable multiprotocol operationSynchronize and latch real-time Ethernet signals for precise timing controlFlexible Host Port Interface (HPI) for connection to an external application processor or for use with a daughter cardEffective reference design for reduced bill of materials (BOM) and compact form factorElectromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) compatible PCB layout
