WARNING: Under no circumstances are negative undershoots, of any amplitude, allowed when device is in battery-backup mode.
Note 1:
Limits at -40°C are guaranteed by design and not production tested.
Note 2:
All voltages are referenced to ground.
Note 3:
Measured at VCC = typ, VBACKUP = 0V, register 08h = A5h.
Note 4:
The use of the 250
Ω trickle-charge resistor is not allowed at VCC > 3.63V and should not be enabled.
Note 5:
Measured at VCC = typ, VBACKUP = 0V, register 08h = A6h.
Note 6:
Measured at VCC = typ, VBACKUP = 0V, register 08h = A7h.
Note 7:
ICCA—SCL clocking at max frequency = 400kHz.
Note 8:
Specified with I2C bus inactive.
Note 9:
Measured with a 32.768kHz crystal attached to the X1 and X2 pins.
Note 10:
Limits at +25°C are guaranteed by design and not production tested.
Note 11:
After this period, the first clock pulse is generated.
Note 12:
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to as the VIH(MIN) of the SCL
signal) to bridge the undefined region of the falling edge of SCL.
Note 13:
The maximum tHD:DAT only has to be met if the device does not stretch the low period (tLOW) of the SCL signal.
Note 14:
A fast-mode device can be used in a standard-mode system, but the requirement tSU:DAT
≥ to 250ns must 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 15:
CB—total capacitance of one bus line in pF.
Note 16:
The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set over the 0V
≤ VCC ≤
VCCMAX and 1.3V
≤ VBAT ≤3.7V range.
Note 17:
This delay applies only if the oscillator is enabled and running. If the oscillator is disabled or stopped, no power-up delay
occurs.
