STMicroelectronics STM32WB15 and STM32WB10 Value Line wireless microcontrollers

Click2Contact

STMicroelectronics has extended its STM32WB Bluetooth LE microcontroller (MCU) offering with devices that combine entry-level features with extra power savings for long-lasting performance.

The dual-core STM32WB15 and STM32WB10 Value Line pair an Arm Cortex-M4 processor to run the main application and a Cortex-M0+ to handle Bluetooth 5.2 connectivity, enabling real-time performance from each. The radio stage has a 102 dBm link budget to enable connection over long distances and integrates balun circuitry to save board space and reduce the bill of materials.

With an ultrapower-saving mode that allows the radio to remain operational, and carefully tailored peripherals and memory, the devices are suited to power-conscious embedded applications including wearables, beacons, smart circuit breakers, trackers, IoT endpoints and equipment for industrial automation.

The software development kit (SDK) for each MCU includes standardised radio protocol stacks and openness to proprietary protocols. A set of security mechanisms enables safe software updates for brand protection and device integrity, with proprietary code read-out protection (PCROP) to guard intellectual property.

The addition of the latest devices means the STM32WB series scales across package variants, offering options including extended GPIOs and pin-to-pin compatibility between similar packages of the portfolio. Users can easily migrate designs between devices to take advantage of different features and memory densities, leveraging pin-compatibility across packages.

The development ecosystem includes STM32Cube certified radio stacks that support various profiles, software expansion packs and sample code; the STM32CubeMX configurator and initialisation code generator; the STM32CubeIDE development environment; a powerful STM32CubeMonitor-RF evaluation tool; and associated Nucleo hardware tools.
