STM32WLE5/E4xx 32-bit Wireless Long-Range MCUs

STMicroelectronics STM32WLE4xx and STM32WLE5xx 32-bit Wireless Long-Range MCUs embed a powerful and ultra-low-power radio compliant LPWAN radio solution consisting of LoRa® (only available in STM32WLE5xx), (G)FSK, (G)MSK and BPSK. The STM32WLE5/E4xx MCUs are designed to be extraordinarily low-power and are based on the high-performance ARM® Cortex®-M4 32-bit RISC core, operating at a frequency of up to 48MHz. The ARM core implements a full set of DSP instructions and an independent memory protection unit (MPU) that enhances the application security.
