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
