STM32F0 MCUs offer real-time performance and low-power operation for cost-sensitive applications
LoRa STM32WLE5 SoC with ultra-low-power STM32 Microcontroller Design
STMicroelectronics has introduced the STM32WLE5 SoC, the LoRa system-on-chip (SoC) for connecting smart devices with LoRa Internet of Things (IoT) using long-distance wireless connections. The SoC combines ST’s ultra-low-power STM32 microcontroller design with a LoRa compliant radio in one single-die and easy-to-use device. The new wireless STM32 SoC simplifies new product development with a reduced bill-of-materials cost, maximum system reliability, and energy efficiency. By using the STM32 MCU architecture, developers can easily introduce wireless connectivity in existing embedded design by porting to the STM32WLE5.
