Hi..I am using STM32U575 NUCLEO ..there are three drive levels are mentioned for LSE...which one one should be used or which is more suitable for low power consumption and I need to know the power consumption in each case (numerical value)..

[ABDUL1]

In the errata sheet,it is mentioned that low drive mode and medium low drive are not working.. but I checked and they work fine...is there any correction in the errata sheet...?..Can I go with low drive mode for LSE (NUCLEO-U575ZQ)???

HI @ABDUL​ 

It's depend on your microcontroleur revision.
 

If you have an Rev W , low drive mode and medium low drive are working. But if you are using a revision version older than this one, they don't work.

I think I am using Rev X (NUU575ZIQ$AT2)

You can check this information by using STM32C ubeProgrammer, in target information , you will find it .

Thanks ,

i confirmed, It is Revision X.not W...but all modes are working....

Anyone can provide the power consumption details of each mode?

I had found those values for L4 boards...u5 boards have the same power consumption??
