nrf5340 I2C operation at 5Vhttps://devzone.nordicsemi.com/f/nordic-q-a/119387/nrf5340-i2c-operation-at-5vHi, We are working with nrf53-DK evaluation board, and we are using P1.02\P1.03 pins for I2C communication. We wanted to connect a 5V I2C slave on these lines can we connect 5V I2C slave. As per the nrf5340 datasheet if it is powered at 3.3V thenen-USTelligent Community 13Thu, 27 Feb 2025 09:20:47 GMTRE: nrf5340 I2C operation at 5Vhttps://devzone.nordicsemi.com/thread/525003?ContentTypeID=1Thu, 27 Feb 2025 09:20:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa8c19fd-2dea-4a42-a2d3-944e2207938dVidar Berg<p>Hi,</p> <p>This will exceed the&nbsp;<a href="https://docs.nordicsemi.com/bundle/ps_nrf5340/page/chapters/abs_max_ratings/doc/abs_max_ratings.html">Absolute maximum ratings</a>&nbsp; for the chip and it may cause damage internally on the chip. If the slave needs to operate on 5V, you will need to&nbsp;place a level-shifter between to translate the IO levels.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
