�ote: 1. I = Input� O = Output� A = Analog po�t� P = Powe� supply� PU = Pull-up� BK = Backup do�ain� EP =

Exposed pad of the QF� package.

�. 33 V = 3.3 V tole�ant.

3. The GPIOs a�e in an AF0 state afte� a VDD15 powe� on �eset (POR) except fo� the RTCOUT pin in the

Backup Do�ain I/O. The RTCOUT pin is �eset �y the Backup Do�ain powe�-on-�eset (PORB) o� �y the

Backup Do�ain softwa�e �eset (BAK_RST �it in BAK_CR �egiste�).

4. The �ackup do�ain of the I/O pins have a sou�ce cu��ent capa�ility li�itation of < � �A @ VDD = 3.3 V

and sink current typical is 4/8 mA configurable @ VDD = 3.3 V.
