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 12.5 pF. An external  
32.768 kHz oscillator can also drive the IDT1338B-31. In this configuration, the X1 pin is  
connected to the external oscillator signal and the X2 pin is left floating.

VBAT  
Backup Supply Input for Lithium Coin Cell or Other Energy Source. Battery voltage must be held  
between the minimum and maximum limits for proper operation. 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.  
Serial data input/output. SDA is the input/output pin for the I2C serial interface. It is an open-drain  
output and requires an external pull-up resistor (2 Kohm typical).

2
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 Kohm typical)  
SQW/OUT Square-Wave/Output driver. When enabled and the SQWE bit set to 1, the SQW/OUT pin  
outputs one of four square-wave frequencies (1 Hz, 4 kHz, 8 kHz, 32 kHz). It is an open drain  
output and requires an external pull-up resistor (10K ohm typical). Operates when the device is  
powered with VCC or VBAT  
.

VCC  
NC  
Device power supply. When voltage is applied within specified limits, the device is fully  
accessible by I2C and data can be written and read.

No connect. These pins are unused and must be connected to ground for proper operation.
