5 reasons to choose the STM32WL MCU for designing the Generic Node
summary
Single-chip solution that combines a Cortex‑M4 application core and a Cortex‑M0+ radio core with on‑chip LoRa and FSK modems, part number stm32wl55ccu6 with 48 pins and 256 KB flash. Measured numbers: run mode ~71 µA/MHz, sleep ~28 µA/MHz, stop ~1 µA retention, TX active ~87 mA, standby ~390 nA with 32 KB retention. Radio spans 150–960 MHz, sensitivity down to -148 dBm and up to 22 dBm output. Development uses STM32Cube tools, CubeWL stack and CubeProgrammer.
