3. Current with oscillator running and all analogue cells active. All outputs unloaded, no floating inputs
4. Current with all analogue cells in power down. Logic is powered but no clocks running. All outputs unloaded, no floating inputs
5. Not valid for pins with internal pull−down resistor
6. Thermal shutdown and low temperature warning are derived from thermal warning.
7. No more than 100 cumulated hours in life time above Tt_w
