Notes:
(1) No more than 100 cumulated hours in life time above T_tsd.
(2) Thermal shutdown and a low temperature warning are derived from thermal warning.
(3) A 10μF buffer capacitor of between VBB and GND is the minimum needed. Short connections to the power supply are recommended.
(4) Pin VDD must not be used for any external supply
(5) The RAM content will not be altered above this voltage.
(6) External resistance value seen from pin SWI or HW, including 1kΩ series resistor.
(7) If input voltages < - 0.3V, than a resistor between 22Ω to 100Ω needs to be put in series
(8) If the I²C-bus is operated in Fast Mode V_IHmin = 0.7 * Vdd
