 Hi, so I'm going to talk about our latest product in the sub-gigar headsband and especially in the unlicensed spectrum So that means Lora 1, SIGFOX, WALAS and BUSIN actually any other proprietary protocol I'm very excited today to have the opportunity to talk about our latest series called STM32WL Which can be used in many long-range applications such as energy management through smart metering But there's also a remote fire detection system to name just a few examples But before providing you with more information about STM32WL itself Let's get back to the basics of sub-gigar heads hardware implementation A natural approach could be to think first of all of a standalone microcontroller Which would manage the intelligence of your application along with a standalone Radio transfer matching your applicative needs Well, that's something which is still feasible of course from a hardware standpoint Especially when considering our large portfolio of general-purpose microcontrollers However in the framework of low-power wide area network We understood from you the customers that there's a clear need for a deep integration along with more development security More flexibility, advanced security features and all of which in a ultra low-power framework So we heard your needs we listened to them and we accepted such a design challenge You are thus the reason why we recently hit the market with a major breakthrough called STM32WL It's actually a system and chip and what does that mean? It means actually that all the technical structure are implemented on the same silicon die So that means the CPUs but also the peripherals of the radio transceiver all of which on the same silicon die Which is in the framework of multimodulation and lower enablement a world first So let's review together your main benefits when using STM32WL So of course we wanted to make sure that you could implement Lora 1, SIGFOX, wireless and boosts or actually any other proprietary protocol on the platform and for this reason there is Multimodulation compatibility so that means Lora modulation, but also GFSK, GMSK and BPSK As just explained the system and chip implementation means that actually There is a deep integration factor and that will lead to massive cost savings for your PCB implementations The platform itself is fully open So that means that you guys device maker will always be free to implement whatever you want on the platform Now in terms of architecture It's actually a dual core architecture based on ARM Cortex M4 and ARM Cortex M0 plus Which brings advanced security features we could think for example of secure key management services Which is a dedicated flash memory area that can be used to store and manage your object in a secure way Such as your applicative keys or protocol or keys for example But also we could mention secure firmware install and secure firmware updates that are useful to flash your devices From an uninterested manufacturing site for example or lastly we could think of chain of trust and root of trust Through secure boot now in terms of packages We have both a BGS 73 and a QFN 48 depending on your needs in terms of GPIO Numbers, but also in terms of cost optimization or footprint The ecosystem offer is also very rich because we ensured that you have all the tools that you will need from configuration up to Flashing of the device so for a configuration you have stn32 cube a mix So that you can configure the pinout, but also automatically generate some code Which is very useful when you want to prototype in a fast way There is stn32 cube IDE to develop your code in a free of charge way Or you can perform RF advanced testing through stn32 cube monitor and last but not least You can also flash your device with stn32 cube programmer Finally, you can also sleep well because we have our usual 10 year longevity commitment, which is actually renewed every year
