Note1: The VBAT pin has low voltage detection function and needs more than the minimum voltage of the VBATopr1 at the boot

up.

Note2: Please refer to other documents (application note) for our connection examples.

Note3: During RF block operation and 26 MHz operation of CPU, this voltage is 1.2 V (typ.).

In other operation it becomes 1.1 V (typ.).
