 it's time to talk securely wireless communications are everywhere today but it's crucial to make sure they're secure we don't want to share our personal data confidential files or our company's IP to address this we are very proud to announce a new STM32 WBA the WBA is a 2.4 gigahertz radio microcontroller designed around security challenges it is based on a cortex m33 running at 100 megahertz and with a coremax core of 407 this new ultra low power platform provides an optimal performance per watt ratio and is based on the same technology as another popular microcontroller the STM32 U5 to enhance the robustness of our communications the STM32 WBA is the first wireless microcontroller to target a CISI level 3 platform certification leveraging STs trusted firmware secure boot secure debug side attack resistant hardware as IP and arms cortex m33 trust zone with its features developers can protect sensitive applications from the radio stack and safeguard information like cloud credential or user data enabling brand protection just like the STM32 U5 the WBA supports low power stop 0 and stop 2 and standby modes this means developers can rapidly switch from a running mode with all the connectivity to the lowest power mode with the radio context written in the memory the STM32 WBA which is plus 10 dBm output power supports long-range transmissions a high-speed data rate of up to 2 megabit per seconds and advertising extensions the WBA 52 is the first WBA to launch and focuses on Bluetooth low energy 5.3 the support for other wireless technologies like open thread and Zigbee will be supported in the future by dedicated part numbers in our demo here the STM32 WBA 52 is being used in a smart home application as a door lock within the application the secure service managing the door lock is executing from the secure area of the WBA 52 this means that nobody can access the keys or the application code and the door pin is completely protected from attack a provisioning service can then run via the smartphone and securely update the keys so providing an end-to-end fully secured service so we have seen the STM32 WBA answers all the needs for a secure energy care wireless device it's readily available now and fully integrated in the STM32 cube ecosystem come check it out
