STM32WL55xx 32-Bit Wireless Long-Range MCUs

STMicroelectronics STM32WL55xx 32-bit Wireless Long-Range MCUs embed a powerful and ultra-low-power LPWAN-compliant radio solution that allows for LoRa^®, (G)FSK, (G)MSK, and BPSK modulations. STM32WL55xx Wireless MCUs are extremely 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 core implements a full set of DSP instructions and is complemented by an ARM Cortex-M0+ microcontroller. Both cores implement an independent memory protection unit (MPU) that refines the application security.
