Notes
(1) No more than 100 cumulated hours in life time above Ttsd
.
(2) Thermal shutdown and low temperature warning are derived from thermal warning.
(3) A 10 µF buffer capacitor of between VBB and GND is 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 HW2, including 1 kΩ series resistor.
