It outputs alarm interrupts and periodic interrupts. 2 SCL I Serial Clock Line. It is for I 2C communication. Data input and output across SDA pin is synchronized with this clock. Up to 6V beyond Vcc may be input. 3 SDA I/O Serial Data Line (Open Drain output). This line is for transferring I 2C bus format data. When input, up to 6V beyond VCC may be used. When output, it is an open drain output pin. 4 GND P Ground 5 /INTA O Interrupt A (Open Drain). It outputs alarm interrupts and periodic interrupts. 6 OSCOUT O Oscillator Circuit Output. Together with OSCIN, an crystal oscillator is connected between them. 7 OSCIN I Oscillator Circuit Input. See OSCOUT pin description. 8 Vcc P Power 8 pin TSSOP 8 pin SOIC |
