NAME
FUNCTION
1
—
X1
2
—
X2
Connections for a Standard 32.768kHz Quartz Crystal. The internal
oscillator circuitry is designed for operation with a crystal having a specified
load capacitance (CL) of 6pF. For more information about crystal selection
and crystal layout considerations, refer to
Application Note 58: Crystal
Considerations with Dallas Real-Time Clocks. An external 32.768kHz
oscillator can also drive the DS1337. In this configuration, the X1 pin is
connected to the external oscillator signal and the X2 pin is floated.
3
14
INTA
Interrupt Output. When enabled,
INTA is asserted low when the
time/day/date matches the values set in the alarm registers. This pin is an
open-drain output and requires an external pullup resistor. The pull up
voltage may be up to 5.5V, regardless of the voltage on VCC. If not used, this pin
may be left floating.
4
15
GND
Ground. DC power is provided to the device on this pin.
5
16
SDA
Serial Data Input/Output. SDA is the input/output pin for the I
2C serial
interface. The SDA pin is open-drain output and requires an external pullup
resistor.
6
1
SCL
Serial Clock Input. SCL is used to synchronize data movement on the serial
interface.
7
2
SQW/
INTB
Square-Wave/Interrupt Output. Programmable square-wave or interrupt
output signal. It is an open-drain output and requires an external pullup
resistor. The pull up voltage may be up to 5.5V, regardless of the voltage on VCC.
If not used, this pin may be left floating.
8
3
VCC
DC Power. DC power is provided to the device on this pin.

N.C.
No Connect. These pins are not connected internally, but must be
grounded for proper operation.
