STM32WL31KBV6
Overview
The STM32WL31KBV6 is an ultra-low power sub-1GHz wireless System-on-Chip (SoC) based on the Arm Cortex-M0+ core running at 64MHz. It combines a high-performance radio transceiver with a 128KB flash MCU to support multiple LPWAN protocols including Sigfox, KNX-RF, and IEEE 802.15.4g. This highly integrated IC is designed for energy-efficient wireless communication in license-free ISM bands between 413MHz and 958MHz.
Why Choose This Part
The device features exceptional power efficiency, consuming as little as 14nA in shutdown mode and roughly 1.4uA in standby with RTC active. Its integrated SMPS optimizes dynamic current consumption to 2.172mA at 16MHz, while the wide 1.7V to 3.6V operating range and 5V tolerant I/Os simplify power supply and interfacing requirements.
Applications
Getting Started
Start development using the STM32CubeWL software package, which includes peripheral drivers and radio stacks. Hardware prototyping is best performed with the NUCLEO-WL33CC1 development board. Engineers can use standard JTAG or SWD interfaces with tools like the ST-LINK/V3 for programming and debugging via the STM32CubeIDE.
