Notes:

1. PD = internal pull-down resistor, PU = internal pull-up resistor, OH = switched to Output High at reset

2. Ground plane

3. VBAT18 represent the internal power supply of the backup power domain, see section “Power Supply” on page 17.

4. VDDIO is the supply voltage for the following GPIO-pins: P1, P2, P8, P12, P14, P16, P17, P18, P19, P20, P21, P23, P24,

P25, P26, P27 and P29, see section “Power Supply” on page 17.

5. VDD_USB is the supply voltage for following the USB-pins: USB_DM and USB_DP, see section “Power Supply” on page

17. For operation of the USB interface, supply of 3.0V to 3.6V is required.

6. This pin is not connected
