Note 10:
Measured with a 32.768kHz crystal attached to X1 and X2.
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 the V
IHMIN
of the SCL signal)
to bridge the undefined region of the falling edge of SCL.
Note 13:
The maximum t
HD:DAT
need only be met if the device does not stretch the LOW period (t
LOW
) of the SCL signal.
Note 14:
A fast-mode device can be used in a standard-mode system, but the requirement t
SU:DAT
≥
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 t
R(MAX)
+ t
SU:DAT
= 1000 + 250 = 1250ns
before the SCL line is released.
Note 15:

—total capacitance of one bus line in pF.
Note 16:
The parameter t

Note 17:
If the oscillator is disabled or stopped,
RST
goes inactive after t

plus the startup time of the oscillator.
Limits at -40°C are guaranteed by design and are not production tested.
All voltages are referenced to ground.
