1
3
X1
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.
2
4
X2
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.
3
5
RESET
RESET. This is a reset signal output. This signal notifies a host processor that the “watchdog” time period
has expired or that the voltage has dropped below a fixed VTRIP threshold. It is an open drain active LOW
output. Recommended value for the pull-up resistor is 5k
Ω. If unused, connect to ground.
4
6
GND
Ground.
5
7
SDA
Serial Data (SDA) is a bidirectional 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.
6
8
SCL
The Serial Clock (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).
71
VBAT
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.
82
VDD
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.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL12027, ISL12027A. For more information on MSL please see
techbrief TB363.
