DESCRIPTION
1X1
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. X1 can also be driven directly from a 32.768kHz source.
2X2
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. X2 should be left open when X1 is driven from external source.
3VBAT
VBAT. This input provides a backup supply voltage to the device. VBAT supplies power to the device in the event that
the VDD supply fails. This pin should be tied to ground if not used.
4GND
Ground.
5EVIN
Event Input (EVIN). The EVIN is an input pin that is used to detect an externally monitored event. When a high signal
is present at the EVIN pin an “event” is detected.
6FOUT
Frequency Output FOUT, Frequency output pin, 15 selectable frequencies. Open drain output.
7SDA
Serial Data (SDA). 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.
8SCL
Serial Clock (SCL). The SCL input is used to clock all serial data into and out of the device.Open drain output.
9IRQ/EVDET Interrupt (IRQ)/Event Detect (EVDET) Output. Multi-functional pin that can be used as interrupt for Alarm and Event
Detect. Open Drain Output.
10
VDD
VDD. Power supply.
