MARKING
PART
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. X1 can also be driven directly from a 32.768kHz source (see “Application Section”
on page 19.)
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 (see “Application Section” on page 19.)
Interrupt Output/Frequency Output is a multi-functional pin that can be used as interrupt or frequency
output pin. The function is set via the control register. This output is an open drain configuration.
Ground.
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.
The Serial Clock (SCL) input is used to clock all serial data into and out of the device. The input buffer on
this pin is always active (not gated).
This input provides a backup supply voltage to the device. V
