RTC not responding

Hi there,
I'm writing a driver for m41t83 RTC IC. I'm trying to start communication with it over I2C (fast mode) and I have no response from the RTC (always get NACK).

I don't know what might cause the problem I send the RTC address 0x68 after the start condition and send write bit but receive a NACK.

Forgive me if it is not the suitable place to post this question as I can't find better section.
