Smart-Meter Device Simplifies Interoperability, Enabling Massive Roll-Outs by Utilities

The smart-meter integrated circuit (IC) with built-in support for the METERS AND MORE open communication standard, which enables widespread interoperability among smart metering equipment using Power Line Communication (PLC). This will help to maximize smart-grid benefits for the environment, consumers and utility companies.

ST’s ST75MM IC is the first to embed hardware and communication protocol support for METERS AND MORE, simplifying meter design to ultimately enable faster, lower-cost and reliable deployments. The METERS AND MORE is an open specification managed by the METERS AND MORE not-for-profit Association comprising leading technology companies and utilities spanning the Americas, Europe and Asia.

Users using the ST75MM can join the METERS AND MORE Association and achieve Certification for their products to enable widespread use by utility companies.

ST implemented METERS AND MORE in its ST75MM IC to benefit from the protocol’s strong features for smart meter and Advanced Metering Infrastructure applications, such as short messages, robust encryption and authentication features, support for network configuration and management, and retransmission management. The ST75MM joins ST’s STarGRID SoC portfolio of smart-meter system-on-chip devices, which also includes the ST7570 supporting IEC 61334-5-1 communication, and the ST7590, which implements the PRIME standard.
