Product Introduction

Overview

The ST75MMTR, produced by STMicroelectronics, is a METERS AND MORE standard compliant power line communication System on Chip (SoC). This device is designed to provide a turnkey solution for advanced metering infrastructures (AMI), sub-metering, Smart Grid applications, command and control networks, and smart home systems. Based on the ST industrial STarGRID™ SoC platform, the ST75MMTR combines a high-performing PHY processor and a protocol controller core, implementing the METERS AND MORE protocol stack. This ensures field-proven, bidirectional data transfer with robust communication efficiency, security, and reliability in various field conditions.
