including wearable devices, home security products, smart lighting, healthcare devices and industrial devices, household appliances, and asset tracking.
ST's STM32WB wireless microcontrollers are based on ST's low-power STM32L4 microcontroller and offer a rich set of peripherals with power-conscious performance. Centered around a 64 MHz Arm® Cortex®-M4 application processor core and an Arm Cortex-M0+ network processor core, with up to 1 MB of on-chip flash and 256 KB of SRAM, the microcontrollers integrate a 2.4 GHz radio transmitter optimized for low power consumption and high RF performance.
The microcontrollers feature multiple power-saving modes, including adaptive voltage scaling, a 13 nA shutdown mode, and an adaptive real-time accelerator to enable zero-wait execution from flash memory. The devices offer state-of-the-art security features such as public-key authorization, client-key storage, and an elliptic-curve encryption engine. The highly integrated microcontrollers also include a crystal-free, full-speed USB 2.0 device, a 32 MHz RF oscillator, analog peripherals, and a Quad-SPI port for connecting to external memory.
The STM32WB microcontrollers are supported by the Nucleo P-NUCLEO-WB55 package, a comprehensive development kit that includes a Nucleo-68 board with a pre-assembled STM32WB55RG microcontroller and a USB backpack with a built-in STM32WB55CG microcontroller.
