NC
No Connection. Do not connect to a signal or supply voltage.
7VBAT
Backup Supply. This input provides a backup supply voltage to the device. VBAT supplies power to the device in the event
that the VDD supply fails. This pin can be connected to a battery, a supercapacitor or tied to ground if not used. See the
Battery Monitor parameter in “DC Operating Characteristics RTC” on page 5. This pin should be tied to ground if not used.
11
SDA
Serial Data. SDA is a bi-directional pin used to transfer data into and out of the device. It has an open drain output and
may be OR’ed with other open drain or open collector outputs. The input buffer is always active (not gated) in normal
mode.
An open drain output requires the use of a pull-up resistor. The output circuitry controls the fall time of the output signal
with the use of a slope controlled pull-down. The circuit is designed for 400kHz I2C interface speeds. It is disabled when
the backup power supply on the VBAT pin is activated.
