STMicroelectronics' New STM32WB Series Dual-Core MCUs

Adding to its line of STM32WB Bluetooth LE microcontroller (MCU), STMicroelectronics has come up with new devices with entry-level features and extra power savings for long-lasting performance. The dual-core STM32WB15 and STM32WB10 Value Line MCUs come with an Arm Cortex-M4 processor to run the main application and a Cortex-M0+ to handle Bluetooth 5.2 connectivity ensuring real-time performance from each.

The radio stage has a 102dBm link budget to ensure reliable connections over long distances and integrates balun circuitry to save board space and reduce the bill of materials. The new ultra-power-saving mode allows the radio to remain operational, and carefully tailored peripherals and memory. This makes the new devices ideal for cost-sensitive, power-conscious embedded applications including wearables, beacons, smart circuit breakers, trackers, IoT endpoints, and equipment for industrial automation.

The Software Development Kit (SDK) for these MCUs includes standardized radio protocol stacks and openness to proprietary protocols with a set of security mechanisms that ensure safe software updates for brand protection and device integrity, with Proprietary Code Read-Out Protection (PCROP) to guard intellectual property.

With these new devices, the customers can easily migrate designs between devices to take advantage of different features and memory densities, leveraging pin-compatibility across packages. The STM32WB15 and STM32WB10 Value Line MCUs are in production now, offering various pin-compatible configurations in the QFN48 package, priced from $1.3986 for orders of 10000 pieces.
