https://devzone.nordicsemi.com/f/nordic-q-a/5846/nrf51822-supply-voltage-rangein nRF51822 product specification a maximum absolute rating of 3.9 Volt is reported, while in electrical specification the maximum voltage is 3.6 Volt. The question is : can the chip withstand , and operate at , a voltage slightly above 3.6 Volt ? en-USTelligent Community 13Thu, 05 Mar 2015 08:16:43 GMThttps://devzone.nordicsemi.com/thread/20417?ContentTypeID=1Thu, 05 Mar 2015 08:16:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6fd15e8d-33a0-4495-8c83-0592f17e59d9Asbj&#248;rn<p>If you power the chip with anything over 3.6 V you will be out of spec and this is not something we can recommend and behavior will not be guaranteed.</p> <p>By applying higher that specified voltage you will most likely shorten the lifespan of the chip as it lead to extra stress on the chip.</p><div style="clear:both;"></div>
