DESCRIPTION
1
X1
The X1 pin is the input of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz
quartz crystal. X1 can also be driven directly from a 32.768kHz source.
2
X2
The X2 pin is the output of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz
quartz crystal.
3
V
BAT
This input provides a backup supply voltage to the device. V
BAT
supplies power to the device in the event that the
V
DD
supply fails. This pin should be tied to ground if not used.
4
GND
Ground.

).
Open drain output, Programmable to be active/disabled in battery back up mode.
7
SDA
Serial Data (SDA) is a bidirectional pin used to transfer serial data into and out of the device. It has an open drain
output and may be wire OR’ed with other open drain or open collector outputs.
8
SCL
The Serial Clock (SCL) input is used to clock all serial data into and out of the device.
9
IRQ
Interrupt Output. Open drain output, active low.
10
V
DD
Power supply.
