Since the 80's, ST has pioneered the market offering robust, viable and cost-effective solutions for communication over power lines.
The ST7540 and ST7538 power-line transceivers are already widely adopted worldwide for command and control applications including large scale automatic meter reading systems and home and building automation solutions. ST is now offering a new breakthrough platform to meet the needs of large-scale smart metering infrastructure deployments and future smart grid scenarios.
The new platform includes different specific SoC implementations (ST757x, ST758x, ST759x)
