NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

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
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.
