Note: 1. I = inp�t� O = o�tp�t� A = Analog po�t� P = powe� s�ppl�� PU = p�ll-�p� BK = Back-�p domain

�. �VT = � V tole�ant; 33V = 3.3 V tole�ant.

3. The GPIOs a�e in an AF0 state afte� a VDD1� powe� on �eset (POR) except fo� the RTCOUT pin in the

Back�p Domain I/O. The RTCOUT pin is �eset b� the Back�p Domain powe�-on-�eset (PORB) o� b� the

Back�p Domain softwa�e �eset (BAK_RST bit in BAK_CR �egiste�).

4. The back�p domain of the I/O pins have a so��ce c��ent capabilit� limitation of <1 mA @ VBAT = 3.3V and

sink c��ent t�pical is 4 mA @ VBAT = 3.3V.
