See PT7C4563 Pin Configuration SOIC-8, TDFN-8 PT7C4363 1 X1 VCC 8 2 7 X2 SQW 3 INT SCL 6 4 5 SDA GND DIP-8 SOIC-8 TSSOP-8 Pin Description Pin no. Pin Type Description 1 X1 I Oscillator Circuit Input. Together with X2, 32.768kHz crystal is connected between them. 2 X2 O Oscillator Circuit Output. Together with X1, 32.768kHz crystal is connected between them. 3 O Interrupt Output. Open drain, active low. INT 4 GND P Ground. Serial Data Input/Output. SDA is the input/output pin for the 2-wire serial interface. The SDA 5 SDA I/O pin is open-drain output and requires an external pull-up resistor. 2 6 SCL I Serial Clock Input. SCL is used to synchronize data movement on the I C serial interface. Clock Output. Open drain. Four frequencies selectable: 32.768k, 1.024k, 32, 1Hz when SQWE 7 SQW O bit is set to 1. 8 VCC P Power.
