Power supply scheme

Figure 22. Power supply scheme

1. To connect BYPASS_REG and PDR_ON pins, refer to Section 2.19 and Section 2.20.

2. The two 2.2 µF ceramic capacitors on VCAP_1 and VCAP_2 should be replaced by two 100 nF decoupling

capacitors when the voltage regulator is OFF.

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

4. VDDA and VSSA must be connected to VDD and VSS, respectively.

Caution:

Each power supply pair (VDD/VSS, VDDA/VSSA ...) 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 good operation of the

device. It is not recommended to remove filtering capacitors to reduce PCB size or cost.

This might cause incorrect operation of the device.
