Power Domains in STM32F401xC
Hello everyone ,
I was reading in the power controller section 5 in RM0368 , I had some difficulties understanding some terms and distinctions and I would like your support please .
The main goal ifor me is to categorize each group of functionalities by their power source as as being Digital VDD , Analog VDDA , VBAT powered .
According to figure 7 page 71 :
The analog domain is ADC , RCs and PLLs and .. etc , I would like to know a complete list of the rest of functionalities associated with the analog Domain , Even in DS9716 Page 18 section 3.13 third Bullet it specify a partial list of blocks but it includes “Reset Blocks” , what does reset block refer to exactly can i conclude safely its the POR , PDR , BOR , PVD blocks exactly or that is not correct or partial .
Regarding digital domain the word “digital” does it mean “Digital peripherals” ?
Why “IO Logic” different from “GPIO peripheral” being a part of digital peripherals ?
For VBAT , what is the functionality of “wakeup logic” and the difference to “standby circuitary” term .
The above inqueries/questions are just an example of some points that is not clear for me , but ideally i need just a small tree like diagram for power sources , with leaf nodes a list of functional compoents in a sharp clear way , if the category can’t be decomposed to a list if subfunctional levels (can’t be disclosed) I just need the functionality of what it does what are input and output as black box .
I know the end inquiry may not be a practical problem but I need it for internal documentation and study purpose .
Thanks too much for any support and help in advance .
