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.

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 V
is activated to minimize power consumption.
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 I
It is an open drain output. The output is open drain and requires a pull-up resistor.
Power Supply. Chip power supply and ground pins. The device will operate with a power supply from
VDD = 2.7V to 5.5VDC. A 0.1µF capacitor is recommended on the V
