Mouser now stocking STMicroelectronics’ Ultra-low-power Wireless Microcontrollers

Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking the STM32WB wireless microcontrollers from STMicroelectronics (ST). Supporting Bluetooth 5.0, ZigBee 3.0, and OpenThread connectivity, the dual-core STM32WB microcontrollers are ideal for a broad range of Internet of Things (IoT) applications, including wearable devices, home security products, smart lighting, fitness and medical devices, industrial appliances, and asset tracking.

ST’s STM32WB wireless microcontrollers, available from Mouser Electronics, are based on ST’s low-power STM32L4 microcontroller, and offer a rich peripheral set 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 Mbyte of on-chip flash and 256 Kbytes 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, 13 nA shutdown mode, and an adaptive real-time accelerator to enable zero-wait-state execution from flash memory. The devices offer state-of-the-art security features including public key authorization, customer key storage, and an elliptic curve encryption engine. The highly integrated microcontrollers also include a crystal-less USB 2.0 Full-Speed device, 32 MHz RF oscillator, analog peripherals, and a Quad-SPI port to connect to external memory.

The STM32WB microcontrollers are supported by the P-NUCLEO-WB55 Nucleo Pack, a comprehensive development kit that includes a Nucleo-68 Board with pre-mounted STM32WB55RG microcontroller, and a USB dongle with onboard STM32WB55CG microcontroller.
