Caution:

Each power supply pair (VDD / VSS, VDDA / VSSA etc.) must be decoupled with filtering

ceramic capacitors as shown in Figure 13. 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.

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 18, Table 19 and Table 20

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.
