Note 1: All voltages are referenced to ground.
Note 2: SCL and WDS only.
Note 3: SDA and SQW/
INT.
Note 4: Limits at -40
°C are guaranteed by design and not production tested.
Note 5: ICCA—SCL clocking at max frequency = 400kHz. WDS inactive.
Note 6: Specified with WDS input and I
2C bus inactive, SCL = SDA = VCC.
Note 7: Measured with a 32.768kHz crystal attached to the X1 and X2 pins.
Note 8: The parameter tOSF is the period of time the oscillator must be stopped in order for the OSF flag to be set over the voltage range of 1.3V
≤ VCC ≤ VCCMAX.
Note 9: A fast mode device can be used in a standard mode system, but the requirement tSU:DAT ≥ to 250ns must 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 tR MAX + tSU:DAT = 1000 + 250 = 1250ns before the SCL line is released.
Note 10: After this period, the first clock pulse is generated.
Note 11: A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIHMIN of the SCL signal) in order to
bridge the undefined region of the falling edge of SCL.
Note 12: The maximum tHD:DAT has only to be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
Note 13: CB—total capacitance of one bus line in pF.
B
Note 14: This parameter is not production tested.
