Wireless MCUs meet wide range of IoT applications

Wireless microcontrollers (MCUs) from STMicroelectronics (ST) are in stock at Mouser Electronics. The STM32WB MCUs support Bluetooth 5.0, ZigBee 3.0, and OpenThread connectivity. They are suitable 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.

The microcontrollers are based on ST’s low-power STM32L4 microcontroller, and offer a rich peripheral set with power-conscious performance.

Centred around a 64MHz Arm Cortex-M4 application processor core and an Arm Cortex‐M0+ network processor core, with up to 1Mbyte of on-chip flash and 256Kbytes of SRAM, the microcontrollers integrate a 2.4GHz radio transmitter optimised for low power consumption and high RF performance.

Multiple power saving modes include adaptive voltage scaling, 13nA shutdown mode, and an adaptive real-time accelerator to enable zero-wait-state execution from flash memory.

Security features including public key authorisation, customer key storage, and an elliptic curve encryption engine.

The highly integrated microcontrollers also include a crystal-less USB 2.0 Full-Speed device, 32MHz RF oscillator, analogue peripherals, and a Quad-SPI port to connect to external memory.

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