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
