https://devzone.nordicsemi.com/f/nordic-q-a/110601/available-i2c-channel-in-nrf52833Hi Everyone, I am using NRF52833 QFN-40 Package. As I know in datasheet, they have mentioned two I2C Channel is available. I am just curious is for all packages of NRF52833, is two I2C Channel available? or any is their variance between packages foren-USTelligent Community 13Fri, 26 Apr 2024 07:31:03 GMThttps://devzone.nordicsemi.com/thread/480816?ContentTypeID=1Fri, 26 Apr 2024 07:31:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b0e69629-24bd-4f4c-988a-33d78cd2c04bPriyanka<p>Hi Saheb,</p> <p>The nRF52833 (in general) has two I2C channels. We have <a href="https://docs.nordicsemi.com/bundle/ps_nrf52833/page/twi.html">the TWI</a>.</p> <p>There is the <a href="https://docs.nordicsemi.com/bundle/ps_nrf52833/page/twim.html">TWI Master(TWIM)</a> and the <a href="https://docs.nordicsemi.com/bundle/ps_nrf52833/page/twis.html">TWI Slave(TWIS)</a> &nbsp;both which are I2C compatible and they both have two instances each, i.e. TWIM0 &amp; TWIM1 , TWIS0 &amp; TWIS1.</p> <p>Please take a look at <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pin.html?cp=5_2_0_3_0#qfn48">the pin assignments</a> for&nbsp;the&nbsp;nRF52832 QFN packaging. You can assign any free GPIO pins to the TWI peripherals, but please make sure that you <a href="https://docs.nordicsemi.com/bundle/ps_nrf52833/page/twi.html#:~:text=you%20must%20disable%20all%20peripherals%20that%20have%20the%20same%20ID%20as%20TWI%20before%20TWI%20can%20be%20configured%20and%20used.">disable any other peripherals that use the same ID as the TWI</a> in order to prevent any anomaly.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
