 So okay, let's continue with USB over STM32 family So now you've got I think a good overview of what we've got as a USB Let's see in all our family what is covered So USB full speed a variable on all STM32 families. That means what we call families for us is a family L for loop-a-words we've got the mainstream with the the series F and then you've got some mainstream and High-performance one with the most powerful one. So It's in all our family. We've got so USB full speed, but not on all device We've got some device without a USB anymore. So you have to to check what you want to do Crystal is less implementation I think we insist a lot of these capabilities on some parts we will see after more details about it So the capabilities I would say to have a device without an external Oscillators I did in your design Then the fact that you've got internet pull-up on the plus line It's not on all them. You've got some who you need to add yourself this pull-up So we both also address this during the hardware design this morning I speed support on the high-performance family and it requires an external fee except on one On one family with a f7 is three which embedded and I speed fee So it could be interesting. We want these features. We've got one part who support it Here are some apps. So with a different family general purpose one the high-performance and the loop-a-words Here you can see what are the capability from the crystal less So we can see that high-performance will address all the OTG for sure host and the high-speed interface and with the usage of an external fee I Will say this some up situation today, but you need to be updated as soon as we've got a new part So don't take it as I will say a Bible You still need to check when we will see a new reference. What is available on it? So for the device only peripheral so on the holder families on the Little package so maximum of eight billion bid directional on point included on point zero So it's a limitation if you were remembered in our theory of USB. We say we can go up to 16 But here we are limited by our way to eight bid directional Support only of a full speed for this device and in the device only peripheral I mean not the OTG one you don't have the five for you have got a dedicated sram And we this sram could be shared with a can device if it's present on the parts So you have to take care about this when you select a product If you want to do can and USB at the same time you have to share the memory and we will see after more details Link with a program management and the battery charging detection support on some device also So here is a sum up so here you've got the size of the buffer available And if it's share or not with the car and you can see that sometime if you are using usb You can choose can at the same time So we just to warn you about this when you select a product and if you want to use can and usb Please check before For the OTG peripheral here. We've got a dedicated DMA controller So I think you remember who both present you the difference yesterday on the fact that you have access to the buses So you can drive a DMA OTG internal pull down for the full speed so no need to add external and it's needed to switch from us to from From full speed to high speed Dedicated 5-4. I think we already cover it yesterday So here is the sum up of all I will say the capabilities for the different family so it could be limited to eight on point and This 5-4 size which is 154 case and if you go in the I would say high performance one in the High-speed you can go to 4k for the 5-4 and the number of on point is 16 On your slide version. There is a mistake there. It was right 18, but it's need to be updated It was 16 just a typo error. Sorry for that so You have to notice that some h7 you can have two OTG high speed so there is two high OTG high speed, but there are The same property properties so but only one could be high speed if one is high speed the other one could High speed and high speed Yeah So that's just to give you an overview of the different capability we see together. I think it's That's all for this pot Any question on these parts? I Would say just information for you after you really have to check when you want to select and don't hesitate to use The finders to find the chip or to to see what you need to address. I Think we switch to another hands-on with low Bosch
