STMicroelectronics Accelerates Wireless Product Development with Market-Leading STM32 Microcontrollers

• STM32Cube ecosystem extended to support STM32WB wireless MCUs
• New STM32CubeWB firmware, upgrades to programmer and RF test tool
• Enhanced wireless power estimator for calculating battery runtime

Jan 29, 2022: STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is easing the design of competitively priced and power-efficient wireless equipment for applications like smart buildings, smart industry, and smart infrastructure by introducing new development tools and software for STM32WB wireless microcontrollers (MCUs).

ST’s highly integrated STM32WB contains a 2.4GHz radio, Arm® Cortex®-M4, and Cortex-M0+ MCU on the same chip, which eliminates numerous RF-circuit design challenges that can add time and uncertainty to a project. Just a small number of external components are needed, such as an antenna chosen for the application, to complete the hardware design. The MCU includes numerous peripherals, including a 12-bit analog-digital converter (ADC), digital interfaces, and a crystal-less USB 2.0 Full Speed interface in selected models. Protocols supported are Bluetooth® LE 5.2, Zigbee®, OpenThread and proprietary protocols, including combinations of such protocols with concurrent modes.

As a member of the STM32 family, the market-leading Arm Cortex-M MCUs, the STM32WB benefits from the extensive and market-proven STM32Cube ecosystem that provides a rich selection of development tools and software.

“The STM32Cube ecosystem is already widely used and is also broadly supported by third-party developer resources that help accelerate project completion,” said Hakim Jaafar, STM32 Wireless Marketing Director, STMicroelectronics. “Our latest wireless enhancements extend the STM32 family’s capabilities to handle new demands and use cases, further enhancing the most complete and robust solution on the market.”
