WARNING: Negative undershoots below -0.3V while the part is in battery-backed mode may cause loss of data.
Note 2:
Limits at -40掳C are guaranteed by design and not production tested.
Note 3:
All voltages are referenced to ground.
Note 4:
ICCA鈥擲CL clocking at max frequency = 400kHz.
Note 5:
Current is the averaged input current, which includes the temperature conversion current.
Note 6:
The
RST pin has an internal 50k
惟 (nominal) pullup resistor to VCC.
Note 7:
After this period, the first clock pulse is generated.
Note 8:
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH(MIN) of the SCL signal)
to bridge the undefined region of the falling edge of SCL.
Note 9:
The maximum tHD:DAT needs only to be met if the device does not stretch the low period (tLOW) of the SCL signal.
Note 10: A fast-mode device can be used in a standard-mode system, but the requirement tSU:DAT 鈮� 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 11: CB鈥攖otal capacitance of one bus line in pF.
Note 12: The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set over the voltage range of
0.0V
鈮� VCC 鈮� VCC(MAX) and 2.3V 鈮� VBAT 鈮� 3.4V.
Note 13: This delay applies only if the oscillator is enabled and running. If the
EOSC bit is a 1, tREC is bypassed and RST immedi-
ately goes high. The state of
RST does not affect the I2C interface, RTC, or TCXO.
