The STM32WBx5 line includes a wide variety of communication features including a practical crystal-less USB 2.0 FS interface, audio support, an LCD driver, touch sensing, up to 72 GPIOs, an integrated SMPS to optimize power consumption optimization, and multiple low-power modes to maximize battery life.The module integrates the full reference design in a small LGA86 package (7 x 11.3 mm) and offers a wide certification coverage. The STM32WBxM line of modules offers the same feature set as the STM32WBx5 line.The STM32WBx0 Value Line focuses on the essentials and offers a feature-optimized, cost-effective solution for developers.STM32WBx5 wireless microcontrollers, available in multiple packages and different memory sizes, provide users with enhanced performance and flexibility to address different levels of complexity.

The innovative architecture of STM32WB MCUs is based on two totally independent cores, optimized for real-time execution (radio-related software processing) and enables flexible resource use as well as power management for a lower BOM cost and a better user experience.ĭeveloped with the same technology as our ultra-low power STM32L4 microcontrollers, the STM32WB MCU series provides the same digital and analog peripherals suitable for applications requiring an extended battery life and complex functionalities. This concurrent feature significantly increases the ease-of-use and overall user experience of these combined technologies. STM32WB MCUs can also run Bluetooth LE 5.2 with 802.15.4 wireless protocols, Zigbee and OpenThread protocols in concurrent modes (Bluetooth LE and Zigbee or Bluetooth LE and OpenThread) for more convenient device management during installation, and configuration once deployed. STM32WB can support entire network topologies with an optimized footprint: Zigbee RFD and FFD deliveries cover end-device to coordinator and router roles Thread MTD, FTD and Border Router deliveries cover from sleepy end-device to router and leader roles, thereby also enabling gateway infrastructures.

Different certified configurations are available to provide more freedom in terms of device sizing and OTA capability, to enable platform optimization. The generic IEEE 802.15.4 MAC layer ensures the STM32WB can run proprietary protocols or full stacks, including Zigbee PRO 2017 and low-power OpenThread Mesh networking protocols, giving designers even more options for connecting devices to the Internet of Things (IoT).

Bluetooth Low Energy RF transceiver comes with certified Bluetooth™ LE 5.2 radio stack, profiles from the Bluetooth SIG, Mesh profile- compliant V1.0 Bluetooth SIG release.Ī BLE LLD for proprietary protocols or a host controller interface (HCI) for Bluetooth Low Energy solutions supporting either Zephyr or Arm Cordio stack, address various integration needs.
