Hello, I'm using the interface I2C of KL25Z128VLK4 to generate a phase sinusoid. I need a frequency of 750kHz, but when the SCL frequency exceed 100kHz, I have a warning: the device is designed to operate up to 100kHz. So I'd like to know the limite maximun of the frequency of I2C of KL25Z.
PS: I have already tried to use a frequency up to 100kHz, but my output can't increase according to this frequency.
Thank your for your answers!
Hi Xiaocong Fu,
The maximum I2C SCL Clock Frequency of the KL25Z128VLK4 MCU is 400 kHz:
Hope it helps!
