1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These

capacitors must be placed as close as possible to, or below, the appropriate pins on the underside of the

PCB to ensure the good functionality of the device.

2. To connect BYPASS_REG and PDR_ON pins, refer to Section 2.2.16: Voltage regulator and Table 2.2.15:

Power supply supervisor.

3. The two 2.2 µF ceramic capacitors should be replaced by two 100 nF decoupling capacitors when the

voltage regulator is OFF.

4. The 4.7 µF ceramic capacitor must be connected to one of the VDD pin.

5. VDDA=VDD and VSSA=VSS.
