China, September 24, 2021 - Global Semiconductor Leaders in Multiple Electronic ApplicationsSemiconductor(STMicroelectronics, referred to as the New York Stock Exchange Code: STM) Released the new STM32WB wireless microcontroller (MCU) development tool and software to reduce design economy, energy saving for the developers of smart buildings, intelligent industries and intelligent infrastructure The difficulty of wireless devices.

Higher intensive STM32WB monolithic integrated 2.4GHz radio frequencytransceiverwithARM® Cortex®-M4 and Cortex-M0 + dual-core microcontrollers, thereby eliminating many radiofrequencyCircuitDesign challenges, because the RF circuit design increases the development time of the project, and will bring a lot of uncertainty to project development. Use a STM32WB development hardware design only requires a small amount of external components, for example, select antenna. STM32WB MCU is equipped with many external settings, including 12 digitsMode digital converter (ADC),numberinterfaceNoCrystal USB 2.0 full-speed interface, specifically according toSelectionNumber. The chip supported protocol includes Bluetooth® Le 5.2,ZigBee®, OpenThreAD And proprietary protocols, including concurrent mode of these protocols.

The STM32 family is a market-leading ARM Cortex-M microcontroller as a member of the product family, and STM32WB is based on market inspections, and has been widely supported and has a widely supported development tool and software resource-rich STM32Cube ecosystem.

HAKIM JAAFAR, Director, Semiconductor STM32, said: "The STM32Cube ecosystem has been widely used, and has been widely supported by third-party developer resources, which helps speed up project development. Our newly launched wireless products expanded The STM32 series handles new needs and use cases, further enhances the market leadership of a robust STM32 solution. "

Technical details: Ecosystem new feature boost wireless design

The STM32WB ecosystem enhances the support of wireless design, providing all the necessary embedded software modules and tools, allowing users to easily develop applications. There are many code examples in the STM32CubeWB MCU software package, and provide a complete set of drivers (HAL and LL) and all necessary RF protocol stacks, including forBluetooth5.2, ZigBee 3.0, OpenThread V1.1 and proprietary protocols 802.15.4 mac, and multiple routines that implement these protocol stacks in a plurality of protocol stacks (static and / or dynamics). The GUI interface of STM32Cubemx and STM32Cubeide and other software tools directly support RF protocol stacks, which is convenient to access and configure these protocol stacks. Users can easily choose and configure Profiles and ClusTERSTo support mainstream standards, and benefit from ready-made code examples.

The STM32Cubemx configument adds additional control functions for power estimation tools to help calculate the impact of the radio frequency subsystem on the overall power calculation. Users can set various scenarios to accurately assess battery life.

There is also more new features, for example, the strengthening of the STM32Cube programmer can optimize the programming function of the STM32WB dual-core architecture, using the Cortex-M0 + processor to control the RF subsystem with the Cortex-M4 primary, to ensure real-time application performance.

With STM32Cubemonitor-RFAssessment tools, ecosystems expand the development process to efficiently install RF and test performance in the customer environment. STM32Cubemonitor-RF supports Bluetooth® Le and General 802.15.4 RF technology to perform transceiver testing and RF performanceMeasurementAnd assist in writing test scripts, test protocols, and command sequences. The latest version is 802.15.4 protocol introduced the detection device function to reduce the development of network products.

All tools and RF protocol stacks in the STM32CubeWB wireless ecosystem have been customized and free, and the detailed documentation of the Bluetooth 5.2 and 802.15.4 certification projects, allowing customers to quickly and economically access to RF product license Certificate.

The STM32WB wireless microcontroller ecosystem also includes a set of STM32WB wireless microcontrollersAssess boardHelp users speed up the development speed of wireless products.

Contains Nucleo-64 development board and USBadapter , Nucleo-WB55RG development board and Nucleo-WB15CC Nucleo-64 development board P- Nucleo-WB55Development kitAnd STM32WB5MM-DK explorationKit To provide users with a variety of functions of immediate development applications, suitable for various wireless applications.

Using the same series of chips, various application design can share the same basic design, make full use of product development and certification investment.

STM32WB products are highly flexible, and different types of different types of products that are high-end to cost can be used, and the application prospects are broad.
