2. The two 2.2 µF ceramic capacitors 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=VDD and VSSA=VSS.

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.

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 13: Voltage characteristics,

Table 14: Current characteristics, and Table 15: Thermal characteristics may cause

permanent damage to the device. These are stress ratings only and functional operation of

the device at these conditions is not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability. The device mission profile (application

conditions) is compliant with JEDEC JESD47 Qualification Standard. Extended mission

profiles are available on demand.
