PIN
NAME
DESCRIPTION
1
X1
2
X2
These signals are connections for a standard 32.768kHz quartz crystal. The internal
oscillator circuitry is designed for operation with a crystal having a specified load
capacitance (C
L
) 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.
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.
3
INTA
4
GND
DC power is provided to the device on these pins.
5
SDA
Serial Data Input/Output. SDA is the input/output pin for the 2-wire serial interface. The
SDA pin is open-drain output and requires an external pullup resistor.
6
SCL
Serial Clock Input. SCL is used to synchronize data movement on the serial interface.
7
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.
8
VCC
DC power is provided to the device on these pins.
