X1  
X2  
Connections for standard 32.768 kHz quartz crystal. The internal oscillator circuitry is  
designed for operation with a crystal having a specified load capacitance (CL) of 7 pF. An  
external 32.768 kHz oscillator can also drive the IDT1339. In this configuration, the X1 pin  
is connected to the external oscillator signal and the X2 pin is left floating.

VBACKUP Backup supply input. Supply voltage must be held between 1.3 V and 3.7 V for proper  
operation. This pin can be connected to a primary cell, such as a lithium button cell.  
Additionally, this pin can be connected to a rechargeable cell or a super cap that can be  
charged using the trickle charger circuit. Diodes placed in series between the backup  
source and the VBAT pin may prevent proper operation. If a backup supply is not required,  
VBAT must be connected to ground.

GND  
SDA  
Connect to ground. DC power is provided to the device on these pins.  
Serial data input/output. SDA is the input/output pin for the I2C serial interface. The SDA pin  
is an open-drain output and requires an external pull-up resistor (2 ktypical).

SCL  
Serial clock input. SCL is used to synchronize data movement on the serial interface. It is an  
open-drain output and requires an external pull-up resistor (2 ktypical).  
SQW/INT Square-Wave/Interrupt output. Programmable square-wave or interrupt output signal. The  
SQW/INT pin is an open-drain output and requires an external pull-up resistor (10 kΩ  
typical).

VCC  
Primary power supply. When voltage is applied within normal limits, the device is fully  
accessible and data can be written and read.  
4 - 13  
NC  
No connect. These pins are unused and must be connected to ground.
