 Hello, good afternoon everyone. Welcome in this session. My name is Shaman Panetski. I am a microcontroller application engineer I'm responsible for supporting customers who use ST microcontrollers, STM32 and STM8 and today I will be glad to present you the material related to STM32 and ultra low power. In terms of STM32 we will focus on L4 family and in terms of ultra low power features We will discuss about operating modes and low power peripherals So this is agenda for our meeting. It will take 90 minutes So we will start with a short introduction related to marketing topics. My colleague will be glad to present you information about STM32 L4 family also about roadmap and some tools related to low power Then we will have a 17-minute session related to hands-ons and we will use for this purpose Nucleo L4-5RE with extension P. So this is the kit we will use today during the session and We believe that based on the knowledge which you will get today You will be able to present how easy is to get started with STM32 L4 How easy is to get started with operating modes, especially low power modes And how easy is to build a complete backbone of low power application So for this purpose, we prepared for you four different hands-ons different in terms of operating modes and different in terms of Peripherals which are used. We will focus only on one hands-on and this will be the first one So this will focus on run mode and external SNPS So I would have a question to you. Can you tell me what SNPS stands for? Switched mode power supply. Exactly. Switched mode power supply So this is a new feature implemented in STM32 L4 as support for external SNPS and this hands-on we will do together today and I believe that this can be very interesting for you because this SNPS solution allows to reduce significantly current consumption of the microcontroller and in fact It doesn't introduce you any serious limitation or drawback So in fact, you can consider using it for wide range of applications and at the end We will have a short conclusions and questions and answer session and also we will use this time to fill in the survey Okay
