STMicroelectronics (NYSE:STM) has launched a new series of long-range wireless microcontrollers, the STM32WL3, designed for energy-efficient connectivity in smart metering, smart building, and industrial monitoring. These MCUs extend battery life beyond 15 years and support multi-protocol communication in license-free ISM frequency bands. They feature a unique ultra-low-power radio that can listen for wake-up signals while conserving energy. Customers like Lierda Internet of Things Technology and Silent Smart Technology are already using these MCUs to enhance their products. The STM32WL3 is part of ST's strategy to integrate the radio with the main application controller, simplifying design and reducing power consumption. The MCUs are available in various configurations and are backed by ST's 10-year longevity guarantee.
