STM32WLE5J8I6

STM32WLE5J8I6 is a multiprotocol LPWAN 32bit Arm® Cortex®-M4 MCU. It is a long-range wireless and ultra-low-power device that embeds a powerful and ultra-low-power LPWAN-compliant radio solution, enabling the following modulations: LoRa®, (G)FSK, (G)MSK, and BPSK. It is designed to be extremely low-power and are based on the high-performance Arm® Cortex®-M4 32bit RISC core operating at a frequency of up to 48MHz. This core implements a full set of DSP instructions and an independent memory protection unit (MPU) that enhances the application's security. The device also embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection and proprietary code readout protection. This device also embeds two DMA controllers (7 channels each) allowing any transfer combination between memory (flash memory, SRAM1 and SRAM2) and peripheral, using the DMAMUX1 for flexible DMA channel mapping.
