AC Electrical Characteristics
(VCC = VCC(MIN) to VCC(MAX), TA = -40°C to +85°C) (Note 1)
WARNING: Negative undershoots below 0.3 V while the device is in battery-backed mode may cause loss
of data.
Note 1: Limits at -40°C are guaranteed by design and are not production tested.
Note 2: All voltages referenced to ground.
Note 3: SCL only.
Note 4: SDA and SQW/OUT.
Note 5: ICCA—SCL clocking at max frequency = 400 kHz.
Note 6: Specified with the I2C bus inactive.
