 Okay, last tab which we have here, which left is the power consumption calculator. What is this? This is the simple tool which can help us to estimate the average consumption in our application. It's not necessary to use this tool when we're creating the project, but I think it's good to know about this tool in case that we will be forced to work with the low power application to check the consumption, at least to check or decide which mode will be better for our application. How is this tool based? This tool is based on the datasheet values. Here you can see on the left side the link on the datasheet where all this data for this tool was taken. In case that you found something which is imprecise, then it will be in the datasheet. In the datasheet section which belongs to the electrical characteristics and the section the supply current characteristics mainly. Okay, then this is how we taken the data. How to work with this tool? We need definitely to select the important variable. Now all these values for the F401 are for the 25 degrees and we need to decide about the power supply because with the power supply is also different different consumption. Usually with the lower voltage you can get better better consumption. Then we will stay with the 3.3 volts. Now if we select the power supply range then we can here create the steps for our sequence in our application. For example we can have a very simple application which will be for the cycle will be 10 seconds. In the 10 seconds we will do some computation. Okay, then here I create the computation then I here create the new step. I select the mode here it will be a run mode it's the normal operation mode. The power scale I use the low because I for example try to run on the way low frequency for the longer time and I will execute the code from the flash. I'm running from the VDD and I will use the battery because my application will be battery operating. Now the frequency I tell that I will run very very slow then I use the 20 megahertz which we have the values for this and I set here the duration of my of my profile which will be I don't know 5 seconds. And the additional consumption for example during this time I will toggle with the LED. Then I add here the static consumption of the pins which is the GPRO but also I need to add the consumption of the driving the LED which will be for example 1 mA. Then here in the results you can see what will be my consumption in this step approximately 4.23 mA. Then I add this step. You can see the step with my parameters is here in this sequence table and here in the graph is my consumption also with the average. Now I can add the second step because my step will take 10 seconds and for the second 5 seconds I will be in the low power mode for example in the stop mode. Again on the 3.3 volts again powered from the battery only I need to configure the clock. I will run the regulator on the low power low voltage mode with the disabled flash then you can see this mode will take me 10 micro amps. Then I again put here the time with the seconds for the 10 seconds. No additional consumption for example my LED will be shut then okay. And you can see this is my power profile. This is my run state. This is my stop mode. You can see the drop during the consumption and this is my average consumption which will be 2.62 mA. Now how to use this calculator. You can decide this consumption is still not good. Can I do something better? And I for example can here in this mode try to not run on the 20 megahertz but do something faster. Then I here change the mode to the medium and I set the maximum frequency and I for example calculate that with this consumption or with this frequency I can do everything in one second. This means that I will be one second in the run mode and rest for example nine seconds in the very deep low power mode. And you can see for example now my average consumption is 1.37 mA. Then this tool can help me to a little bit estimate my average consumption to decide which mode can be better for my application. If do something very fast or do something very very slow for the longer time. This is usually very nice. Now I can also here select for example the battery. In case that I here in the in the my modes I select here the voltage source as a battery. I can here select one battery for example this one. Here is the voltage of the battery sorry. Here is nominal voltage then I select something bigger the same as my as my mode as we vote okay. Maybe a little bit bigger this one okay. Here is the maximum current the the capacity and I put it into my into my application and here try for me calculate with the average consumption the lifetime of my battery. Now with this mode I can it can take two years eleven months two days and the seven seven hours. Then for this can be very easily used the power consumption calculator. Also don't forget adhere the additional consumptions because we cannot measure all the values like what is the what is the having capability of the pins if we have there the long cable or the short cable you need to create your own assumption of this consumption okay. The one point here also you can see my sequence time it's the 10 seconds and there is the temperature. What mean the maximum temperature because also when the chip is powered the the power also increase the temperature inside the chip then this our consumption give us also the maximum temperature when we can put our device our maximum output temperature is 102.75 degrees of Celsius. Okay this is about the modes you can also save your sequence if you want you can open the sequence from the file you can definitely delete current sequence or you can also compare two sequence into in in your different projects to compile which settings will be will be better and also you can move the sequence the order the sequence or the delete or other the steps or clone the steps like here I will duplicate my step and I have this step here twice I can again delete it then definitely this tool can help you to a little bit check which mode will be better for your for your application profile because we cannot 100% be sure that this profile will be perfect for the older applications it's impossible sometimes you need to check because all application are usually unique and for each application can be can be better different profile
