Available I2C Channel in NRF52833

[Saheb]

Hi 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 for communication channels? Can you clarify? 

    Also, it would be helpful if you suggest the I2C pins in NRF52833 QFN-40 Package. 

Thanks & Regards,

Saheb

Hi Saheb,

The nRF52833 (in general) has two I2C channels. We have the TWI.

There is the TWI Master(TWIM) and the TWI Slave(TWIS)  both which are I2C compatible and they both have two instances each, i.e. TWIM0 & TWIM1 , TWIS0 & TWIS1.

Please take a look at the pin assignments for the nRF52832 QFN packaging. You can assign any free GPIO pins to the TWI peripherals, but please make sure that you disable any other peripherals that use the same ID as the TWI in order to prevent any anomaly.

Regards,
