I am using atecc508a-mahaw-s in my device. I haven't managed to wake up or communicate with atecc508a over i2c. During communication I always get NACK as response. During wake up , I respect all time requirements needed.
I'm not sure that atecc508a-mahaw-s is used with i2c or single-wire interface, I wasn't able to find answer on web.
I would be grateful if someone had the answer to that question.
My best regards.
