REAL-TIME CLOCK WITH BATTERY BACKED NON-VOLATILE RAM
Note 7: Measured with a 32.768 kHz crystal on X1 and X2.
Note 8: After this period, the first clock pulse is generated.
Note 9: A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the V
the SCL signal) to bridge the undefined region of the falling edge of SCL.
Note 10: The maximum t
signal.
Note 11: A fast-mode device can be used in a standard-mode system, but the requirement t
then be met. This is automatically the case if the device does not stretch the LOW period of the SCL signal. If such
a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line t
