DESCRIPTION
1
X1
The X1 pin is the input of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz
quartz crystal. The required crystal load capacitance is 6pF. This pin can also be driven by an external 32.768kHz oscillator
with X2 pin floating.
2
X2
The X2 pin is the output of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz
quartz crystal. The required crystal load capacitance is 6pF.
3IRQ2
Interrupt Output 2 is a multi-functional pin that can be used as an alarm interrupt. This pin is open drain and requires
an external pull-up resistor. This pin is at high impedance at power-up.
4
GND
Ground
5
SDA
Serial Data (SDA) is a bidirectional pin used to transfer serial data into and out of the device. It has an open drain output
and may be wire OR’ed with other open drain or open collector outputs.
6
SCL
The Serial Clock (SCL) input is used to clock all serial data into and out of the device.
7IRQ1/FOUT Interrupt Output 1/Frequency Output is a multi-functional pin that can be used as an alarm interrupt or frequency output
pin. The function is set via the configuration register. This pin is open drain and requires an external pull-up resistor. It
has a default output of 32.768kHz at power-up.
