Smart Grid Revolution: STMicroelectronics Launches Game-Changing Communication Chip
Geneva, Monday, 18 November 2024.
STMicroelectronics introduces the ST85MM, a breakthrough programmable chip combining powerline and radio communication for smart meters. This innovative solution addresses the growing demands of modern power grids while supporting multiple communication standards, promising enhanced efficiency and real-time monitoring capabilities for utilities worldwide.
Understanding the ST85MM
The ST85MM from STMicroelectronics is a sophisticated System-on-Chip (SoC) designed to enhance smart grid communications. This component integrates powerline communication (PLC) with radio communication capabilities, featuring an Arm Cortex-M4 core and a digital signal processor. This combination supports efficient execution of PLC tasks, offering high data throughput and secure communication, which are crucial for modern smart grids that require real-time data sharing and monitoring[1].
Features and Performance
One of the standout features of the ST85MM is its support for multiple communication standards, including PRIME 1.4 and Meters and More. These standards ensure compatibility across diverse utility infrastructures, addressing one of the major challenges of older metering systems that lack flexibility. The chip’s hybrid functionality, combining PLC with an S2-LP ultra-low power RF transceiver, makes it ideal for space-constrained smart meter designs, providing versatility in application[1][2].
Pros and Cons
The primary advantage of the ST85MM is its ability to integrate seamlessly into existing smart grid infrastructure, providing a future-proof solution that supports both current and emerging communication standards. However, the reliance on cutting-edge technology might pose a challenge for utilities that haven’t yet upgraded their systems to accommodate such advanced devices. Despite this, the benefits of high accuracy, low latency, and rapid response in energy consumption reporting make it a compelling choice for forward-thinking utilities[1][2].
Comparisons with Similar Products
Compared to other solutions like the ST8500, which also supports hybrid connectivity through PLC and RF, the ST85MM is more focused on metering applications, with its compact package size of 7 mm x 7 mm making it particularly suitable for embedded designs. While the ST8500 offers broader applications in smart grid environments, the ST85MM’s targeted approach for smart meters highlights its specialized role in the infrastructure[3][4].
Use Cases and Recommendations
The ST85MM is ideally suited for utilities looking to upgrade their metering infrastructure to support modern smart grid requirements. For urban and rural settings where accurate, real-time data is crucial, this SoC provides the necessary technological backbone. It’s recommended for energy distributors who need to manage supply and demand more efficiently and wish to reduce costs and carbon emissions through improved energy management[2][5].
