Hi Janz bai,
Thanks for your reply
I have verified datasheet chapter 5

Can i add all these current and consider as total current for controller.

Thanks,

Hello Darvin,

You can refer to the Figure4-1 in the chapter Auxiliary Supply Operation. And I recommend you to read the related part about the supply in the TRM.

The AUXVCC1 and AUXVCC2 are the auxiliary supply. For the core logic and IO, just one of the DVCC, AUXVCC1 and AUXVCC2 will be chosen to use. For the Analog Modules, just one of the AVCC, AUXVCC1 and AUXVCC2 will be chosen to use.

Best Regards,
