NAME
FUNCTION
1
VCC2
Backup Power Supply. This is the secondary power supply pin. In systems
using the trickle charger, the rechargeable energy source is connected to this
pin.
2
VBAT
Battery Input for Any Standard +3V Lithium Cell or Other Energy
Source. If not used, VBAT must be connected to ground. Diodes must not be
placed in series between VBAT and the battery, or improper operation will
result. UL recognized to ensure against reverse charging current when used
in conjunction with a lithium battery. See “Conditions of Acceptability” at
3
X1
5
4
X2
Connections for Standard 32.768kHz Quartz Crystal. The internal
oscillator is designed for operation with a crystal having a specified load
capacitance of 6pF. For more information on crystal selection and crystal
layout considerations, refer to Application Note 58, “Crystal Considerations
with Dallas Real-Time Clocks.” The DS1306 can also be driven by an
external 32.768kHz oscillator. In this configuration, the X1 pin is connected
to the external oscillator signal and the X2 pin is floated.
7
5
INT0
Active-Low Interrupt 0 Output. The
INT0 pin is an active-low output of
the DS1306 that can be used as an interrupt input to a processor. The
INT0
pin can be programmed to be asserted by Alarm 0. The
INT0 pin remains
low as long as the status bit causing the interrupt is present and the
corresponding interrupt enable bit is set. The
INT0 pin operates when the
DS1306 is powered by VCC1, VCC2, or VBAT. The INT0 pin is an open-drain
output and requires an external pullup resistor.
8
6
INT1
Interrupt 1 Output. The INT1 pin is an active-high output of the DS1306
that can be used as an interrupt input to a processor. The INT1 pin can be
programmed to be asserted by Alarm 1. When an alarm condition is present,
the INT1 pin generates a 62.5ms active-high pulse. The INT1 pin operates
only when the DS1306 is powered by VCC2 or VBAT. When active, the INT1
pin is internally pulled up to VCC2 or VBAT. When inactive, the INT1 pin is
internally pulled low.
