SCL
Serial Clock. The SCL input is used to clock all serial data into and out of the device. The input buffer on this pin is always
active (not gated). It is disabled when the backup power supply on the VBAT pin is activated to minimize power
consumption.
13
IRQ/FOUT
Interrupt Output/Frequency Output (Default 32.768kHz frequency output). This dual function pin can be used as an
interrupt or frequency output pin. The IRQ/FOUT mode is selected via the frequency out control bits of the control/status
register. Interrupt Mode. The pin provides an interrupt signal output. This signal notifies a host processor that an alarm
has occurred and requests action. It is an open drain active low output. Frequency Output Mode. The pin outputs a clock
signal, which is related to the crystal frequency. The frequency output is user selectable and enabled via the I2C bus. It
is an open drain output. The output is open drain and requires a pull-up resistor.
14
VDD
Power Supply. Chip power supply and ground pins. The device will operate with a power supply from VDD = 2.7V to
5.5VDC. A 0.1F capacitor is recommended on the VDD pin to ground.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil plastic packaged products employ special material sets, molding compounds and 100% matte tin plate plus anneal (e3) termination
finish. These products do contain Pb but they are RoHS compliant by exemption 7 (lead in high melt temp solder for internal connections) and
exemption 5 (lead in piezoelectric elements). These Intersil RoHS compliant products are compatible with both SnPb and Pb-free soldering
operations. These Intersil RoHS compliant products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL12022M. For more information on MSL please see techbrief TB363.
