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. X1 can also be driven directly from a 32.768kHz source.
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.
3VBAT
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.
4
GND
Ground.
5
NC
No Connection
6FOUT
Frequency Output (FOUT). Open drain output, Programmable to be active/disabled in battery back up mode.
7
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.
8
SCL
The Serial Clock (SCL) input is used to clock all serial data into and out of the device.
9IRQ
Interrupt Output. Open drain output, active low.
10
VDD
Power supply.
