PL360 Host Controller

Introduction

The PL360 is a multi-protocol modem for the Power Line Communication (PLC) device, implementing a very flexible

architecture and allowing the implementation of standard and customized PLC solutions. It has been conceived to be

bundled with an external Microchip MCU, which downloads the corresponding PLC firmware and controls the

operation of the PL360 device.

The purpose of the PL360 Host Controller is to provide the external microcontroller a way to control the PL360 device

and offer upper layers an easy way to get access to PLC communication.

As an example of the PLC system, the figure below shows the system architecture for G3 protocol based on a PL360

device being controlled by a SAM4C MCU.
