 So there was just an example of course we do also show here then the latest let's say arriving protocol matter Where we have a first solution and we are preparing it to bring it on the market in the coming Weeks, let's say, but yeah, you can see the first demo already over here. Now. Let's go back to the u5 Sorry guys, but I see now the booth is available because that is very nice An interesting feature of the u5 So, yes, let me welcome to Manuel. Oh, nice to meet you. Hi So I'm gonna please tell us something about the u5. Yes, the focus on the low power What is so unique inside is microcontroller to make it so special for the low power consumption? Yeah, so it's there are two main reasons. So two main important features one is Security, but here we are focusing on the power. So on these microcontroller u5 We have a dedicated State machine which is working independently from the core So the core is off all the same stop to and the peripherals can work autonomously because the CPU is not fetching an instruction. We have a dedicated DMA instances, which is a low power DMA which is fetching the instructions instead of the CPU So you have a subset of peripherals that you can use when the core is in stop mode. So These modalities call it low power background autonomous mode and right now is a special feature for STM42 u5. I Can show you what are the peripherals that you can use and some use cases you can use Communication peripherals like I to see spy you are in fact, this is what we are demonstrating here and we'll show you later We are demonstrating a night to see reading from an accelerometer and in addition You have a dedicated 12-bit ADC for this low power domain, which is called the smart run domain that you can use to store your data The data are stored in a dedicated SRAM and down to stop to you have 16 k bytes of SRAM available and You can decide to wake up then the core on the strategy. You prefer transfer complete transfer complete Or when you reach a certain threshold, for example And other peripherals which are available are duck for digital to analog converter low power timer You can also create control loops because you have also some analog peripherals which are available comparators opamps And you have dedicated low power so you which are available and very interesting for example for implementing your own data transmission protocol In general what you can do is changing a different peripheral to achieve your task and Keeping the MCU in low power and achieving Ultra low power consumption. So with this solution you can cut your power consumption by a factor 10 16k 16k of RAM down to stop to so it means that when you Initialize you build your function Your LPBAM application you have to be sure that the variables and the handlers that you use in your application are stored in these 16k bytes When the memory is full you can then wake up your core Do some computation and then come back to your task for example smart strategy Yes, yes, this is a Very smart strategy and other interesting fact is that For example, when you're doing an analog conversion, you can also decide to wake up on on a threshold So when you have a certain value you can decide to wake up the core Somebody's asking 128k SRAM would be better Yeah, so You can definitely use more RAM if you go to higher power states We have to say that for the solution for the implementation We've seen so far and customers using LPBAM 60k is pretty okay because you can always wake up for a while doing your operation with 160MHz and then come back to stop to and Go on with your with your low ultra low power tax so Maybe I can give you a short overview or the demo we are presenting here So we are reading an accelerometer via I2C3. We have a dedicated I2C3 instance, which is I2C3 free and The acquisition from the sensor is triggered by a low power timer And the same timer is also triggering another timer which is a low power timer free which is generating a completely independent task with modulated PWM So we basically have two DMAs channel doing two different tasks one is Configuring and reading data from the sensor here We are reading two times six bytes from the sensor and we have another DMA channel, which is taking care of generating Variable PWM in circular mode and to do so we use our U585 disco board Which has accelerometer and gyroscope on it and also some nice connectivity Wi-Fi and belief and our power shield That is based on L490 with our cube and we have I2C Signals if I stop the acquisition you will see that The sampling time is around one millisecond and on the third Channel we have the modulated PWM. Then we have the other free channels, which are used for debugging purposes to see What's going on in the smart and domain in fact This is a very clever way to debug low power application when these three signals which are cd stop ssd Stop are high. It means we are in stock tool and when this signal is toggling it means We have DMA transfer happening now. We measure the consumption with our X nuclear PMA is zero one and our cube monitor power. I will show you So We're now measuring the consumption the application is running with cuba money for power one very interesting feature is that you can select your time window and you can have a calculation of the average power and the average current That is used. So in this case with low power background autonomous mode and one millisecond We are in the range of 61 micro amps We have built an application which is using instead Another Which is using what we call legacy mode, so we are we have built a benchmark application Which is not using a pee bomb. So you have to imagine that the the core has to wake up when the transfer is happening and You keep on switching between stop to and run to do this transfer So we can also demonstrate in this case that if I flash for example the example that It's using this legacy mode. Okay. I will show you We Can observe two things okay from this logic analyzer first What is happening on this free channel is a bit different from what we saw before these lines are toggling It means I'm waking up very frequently. Okay, which is not very good for power consumption So in fact if I measure The power consumption with this legacy application You will see that the values are Around 180 micro amps versus 60 micro amps. So we are gaining a factor free of Of power with These low power background autonomous mode. So we can generalize the result saying that With STM42 U5 and low power background autonomous mode You can achieve great benefit in terms of power saving up to a factor 10 In this case we demonstrate also that the game you have is increasing As we increase the sampling frequency of the I2C interface and this result is valid for I2C UART and SPI so for all communication interfaces that we have on STM42 U5 If you want to discover more I Leave you with some reference links from our Application nodes which are mainly related to low power and to one of our latest on-demand webinar Which is in fact showing how to build this application from scratch Thank you very much Thanks, Manuel. Very great pitch. Thank you. Thanks. We have any questions Sounds like the STM32 U5 as a beast. Yes. Yes, it's really you know It's our latest product based on the 14-millimeter technology. So very progressive and latest one And really the combination of performance security and low power enable this To create at the many of our customers, let's say the dreaming applications
