STM32WL3RKBV6
Overview
The STM32WL3RKBV6 is an ultra-low power wireless System-on-Chip that combines an Arm Cortex-M0+ core running at 64MHz with a sub-1GHz radio. It supports multiple modulation schemes including GFSK, 4-GFSK, and OOK across the 413-479MHz and 826-958MHz frequency bands. This SoC is designed for long-range communication in power-constrained environments, offering a high output power of 20dBm and integrated power management with a built-in SMPS.
Why Choose This Part
This SoC reduces bill-of-materials costs by integrating a high-performance sub-1GHz radio and MCU into a single 5x5mm VFQFPN package. It delivers exceptional range with its 20dBm power amplifier and high receiver sensitivity while maintaining ultra-low power consumption for battery-operated devices.
Applications
Key Specifications
Getting Started
Development is supported by the STM32Cube ecosystem, including STM32CubeWL software packages and the STM32CubeIDE. Engineers can use the ST-LINK/V3 for programming and debugging via SWD or JTAG interfaces. For hardware evaluation, look for NUCLEO-WL33 series boards to prototype sub-1GHz RF performance.
