Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 21: Voltage characteristics,

Table 22: Current characteristics and Table 23: 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.

sensitivity characteristics

1. sAullpmplayi,ninpothweepr e(VrmDiDtt,eVdDrDaAn)gaen. d ground (VSS, VSSA) pins must always be connected to the external power

2. VIN maximum must always be respected. Refer to for the maximum allowed injected current values.

3. Valid only if the internal pull-up/pull-down resistors are disabled. If internal pull-up or pull-down resistor is

enabled, the maximum limit is 4 V.
