1.0 INTRODUCTION

The LAN867x is a high-performance 10BASE-T1S single-pair Ethernet PHY transceiver that is targeted for 10 Mbit/s

half-duplex networking over a single pair of conductors.

This document guides you in creating a sample TCP/IP Client node (bare-metal or FreeRTOS™ based), using the

LAN867x PHY. It describes how to configure the PHY in either Physical Layer Collision Avoidance (PLCA) or Carrier-

Sense Multiple Access/Collision Detection (CSMA/CD) mode.

The description in this document is based on an ATSAME54P20A running on a SAM E54 Curiosity Ultra Development

Board [4]. However, it can also be applied to other infrastructures; for example, to an ATSAME70Q21B running on a

SAM E70 Xplained Ultra Evaluation Kit [5].

1.1 Audience

This document is written for developers who want to create a sample TCP/IP Client node, using the LAN867x PHY.

Developers should be familiar with the infrastructure of MPLAB

® X IDE and its plug-ins [1].
