OUT. ALM. LVRST Pin Descriptions PIN NUMBER SYMBOL DESCRIPTION 1 N/C No connect. 2X1 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. 3X2 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. 4VBAT 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. 5GND Ground. 6 LVRST Low Voltage Reset pin for VCC Brown Out Mode. Open drain Configuration 7 N/C No connect. 8 N/C No Connect 9FOUT FOUT Frequency Output, Frequency selectable through Control Register 10 SDA Serial Data (SDA). SDA is a bi-directional 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. 11 SCL Serial Clock (SCL). The SCL input is used to clock all serial data into and out of the device. 12 IRQ Interrupt Output IRQ. Interrupt pin. Open drain configuration. 13 VDD VDD. Power supply. 14 N/C No connect.
