STMicroelectronics STCOM05

Description

The STCOM is a device that integrates a power line communication (PLC) modemand a high-performance application core.The PLC modem architecture has been designed to target EN50065, FCC, ARIB compliantPLC applications. Together with the application core, it enables the STCOM to support thePRIME, G1, G3, IEEE 1901.2, METERS AND MORE® and other narrow band PLC protocolspecifications
