I2C bus capacitance to define external pull up

[E. Chevalier]

Hi,

I would like to know the I2C bus capacitance for the nrf52840. Do someone have the information please ?

My slave components are compliant for 400Khz and VDD is 3.3V. I put 2k2 pull up on SDA and SCL lines.

Thank in advance for your help,

Best regards,

The pin (GPIO) capacitance is ~4 pF
