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. This device is designed to be extremely low-power and is based on the high-performance Arm® Cortex®-M4 32bit RISC core operating at a frequency of upto 48MHz. This core implements a full set of DSP instructions. It is complemented by an Arm® Cortex®-M0+ microcontroller. Both cores implement an independent memory protection unit (MPU) that enhances the application's security. This device embeds high-speed memories (256-Kbyte flash memory, 64-Kbyte SRAM), and an extensive range of enhanced I/Os and peripherals.
