Brief Description
X1.
The X1 pin is the input of an inverting amplifier and should be connected to one pin
of a 32.768kHz quartz crystal.
X2.
The X2 pin is the output of an inverting amplifier and should be connected to one pin
of a 32.768kHz quartz crystal.
Interrupt Output – IRQ.
This is an interrupt signal output. This signal notifies a host proces-
sor that an alarm has occurred and requests action. It is an open drain active low output.
V
SS
.
Serial Data (SDA).
SDA is a bidirectional pin used to transfer data into and out of the
device. It has an open drain output and may be wire ORed with other open drain or open
collector outputs.
Serial Clock (SCL).
The SCL input is used to clock all data into and out of the device.
V
BACK
.
This input provides a backup supply voltage to the device. V
BACK
supplies power
to the device in the event the V
CC
supply fails. This pin can be connected to a battery, a
Supercap or tied to ground if not used.
