DESCRIPTION
1
X1
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.
2
X2
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.
3
V
BAT
V
BAT.
This input provides a backup supply voltage to the device. V
BAT
supplies power to the device in the event that
the V
DD
supply fails. This pin should be tied to ground if not used.
4
GND
Ground
.
5
EVIN
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.
6
EVDET
Event Detect Output
, active when EVIN is triggered. Open drain output.
7
SDA
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.
8
SCL
Serial Clock
(
SCL
). The SCL input is used to clock all serial data into and out of the device.
9
IRQ/F
OUT
Interrupt Output IRQ, /Frequency Output F
OUT.
Multi-functional pin that can be used as interrupt or frequency
output pin. The function is set via the configuration register.
