Electrical characteristics

6.2

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 18: Voltage characteristics,

Table 19: Current characteristics and Table 20: 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.

Table 18. Voltage characteristics(1)

1. All main power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external power

supply, in the permitted range.
