Pin Descriptions
PIN # SYMBOL
DESCRIPTION
1X1
Crystal Input. 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.
2X2
Crystal Output. 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. X2 should be left
open when X1 is driven from external source.
3VBAT
Backup Supply. This input provides a backup supply
voltage to the device. VBAT supplies power to the device
in the event that the VDD supply fails. This pin should
be tied to ground if not used.
4GND
Ground.
5SDA
Serial Data. SDA is a bi-directional 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.
6SCL
Serial Clock. The SCL input is used to clock all serial
data into and out of the device.
7
IRQ/FOUT Interrupt Output/Frequency Output. Multi-functional
pin that can be used as interrupt or frequency output
pin. The function is set via the configuration register. It
is an open-drain output.
8VDD
Power Supply.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is 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.
