Introduction

PL360G55CB-EK is an evaluation kit for the PL360 modem. PL360 is a programmable modem for
narrow-band Power Line Communication (PLC) from Microchip Technology Inc, able to run any PLC
protocol in the frequency band below 500 kHz. The PL360 has been conceived to be driven by external
Microchip host controller devices; in this case a SAMG55 ARM
Microchip host device loads the corresponding PLC-protocol firmware and then controls the PL360
modem operation.
The PL360G55CB-EK board has been conceived to communicate in CENELEC B-Band (95 kHz to 125
kHz) and it complies with CENELEC standard EN 50065 regulations and Smart Energy applications. It
can be connected directly to AC mains or DC power rails.

    Evaluation Kit Specifications Safety Recommendations This evaluation board must only be used by expert technicians. The PL360G55CB-EK board is powered from a DC power source, so only the PLC coupling stage could have a hazardous voltage when is connected to mains. The risk of electric shock is minimized since all required connectors and configuration jumpers are galvanically isolated from the coupling stage.
