 Welcome to this video about SGM32L5 Ultra Low Power MCU. My name is Martin Hubeek and in this video we will talk about features and architecture of SGM32L5 which is based on the new ARM Cortex M33 core. We will introduce features which can significantly help to achieve low power consumption of an application and to extend the battery lifetime. Finally, we will cover some of the common misconception and myths about comparing various ultra low power MCUs. Here is an agenda that we prepare for today. We will start with an overview of SGM32L5 series with focus on its key elements related to low power. Then we will discuss about architecture of SGM32L5 which is optimized in terms of performance and efficiency of computation. After theoretical part we will do two hands-ons. Second hands-on will be about performance and will be based on core mark benchmark. Second hands-on will also use core mark but this time it will show you the correlation between performance and low power. Later on we will introduce to you low power modes which are available on SGM32L5 with focus on consumption and wake up time. Here again theory will be followed by hands-on of typical low power application. At the end of the session we will summarize the most important things that we discuss today. I will now hand over to my colleague Carsten to do the marketing part. Hello everybody. My name is Carsten Spiek and I am from the technical marketing team for SGM32 microcontrollers. In the beginning of this session I would like to introduce to you our latest low power microcontroller with exciting new features, the new SGM32L5 family. The SGM32L MCU series is the largest portfolio of ultra low power MCUs that exists today. This series is at the heart of our battery operated or energy sensitive applications. The SGM32L1 has a broad range of products and is the foundation of the SGM32 ultra low power series. The SGM32L0 is the cost smart ultra low power champion microcontroller series and it is based on the Cortex M0 plus core. The SGM32L4 completes the ultra low power microcontroller series providing more best in class power consumption figures, higher performance, more advanced peripherals and more memory. The SGM32L4 plus series extends the SGM32L4 technology by offering higher performance, larger embedded and more advanced graphic features with no compromise on its ultra low power consumption capability. The SGM32L5 adds more security with Cortex M33 and its trust zone. Thanks to this new core and new STRRT accelerator which supports also now external memory, the SGM32L5 reaches up to 427 core marks. The SGM32L5 is our first microcontroller based on the new Cortex M33 core. With this core, the SGM32L5 features more security with trust zone and other ST security implementations. Thanks to the ultra low power technology, the L5 has also improved low power consumption. Together with our well known extensive ecosystem, the SGM32L5 becomes the best choice for applications where security and low power matters. The trust zone concept of the SGM32L5 is practically dividing the device in two parts. The trusted and the untrusted. All peripherals which are assigned to the trusted part can only be used by the trusted application and are not reachable by the untrusted application part. It behaves as if there are two independent micros in the application. This ensures a full isolation of trusted and untrusted worlds. Also on the security side, we made a big step forward. Beside the well known security features from the SGM32 family, the L5 is adding new state of the art features like public key acceleration for elliptic curve cryptography, active anti-temper, height protect, unique boot entry on the flight encryption for external memories and secure firmware installation. The SGM32L5 offers best in class power consumption figures with a full flexibility. The user can select the mode depending on the wake up time, the state of retention and the number of sources required. For example, the VBAT mode consumes only three nano amps without real time clock and two hundred nano amps with real time clock running or there is a standby mode with the possibility to keep 16 kilobytes of SRAM with more wake up sources. Wake up time is 14 microseconds only. With these possibilities, the user can select the optimal usage scenario to benefit from ultra low power consumption and fast wake up time of the application. The new Cortex-M33 core is providing more computation power at the same clock speed than the former M4 core. At the same speed, the M33 has about 20% more performance. And thanks to the new ST-RRT accelerator, also the execution of code from external memory is significantly speed up. Looking at the whole block diagram, you can see the extensive set of peripherals which makes the STM32 L5 a good choice for consumer, low power and also demanding industrial applications. Besides a 512 kilobyte flash and a 256 kilobyte SRAM memory, the L5 features crystal less USB, CAN-FD, octa-SPI for external memory, two 5-megasample fast ADCs, two comparators and two op-amps, a huge set of timers and a 16-bit parallel interface. Looking at the available packages, you can see that the STM32 L5 family has a large offer from 48 pin QFN up to 144 pin LQFP. At this range, there are also variants which are a perfect match for applications which have a tight space constraints. The 81 pin WLCSP for example has a size of only 4.36x4.07mm and the UFBGA-132 is only 7x7mm big. I hope you are now aware of the key features of the new STM32 L5 family. Thank you for your attention and let's move on to the next part of the workshop.
