PT7C4563BQ Pin Configuration
SOIC-8 1 X1 VCC 8 2 X2 SQW 7 3 INT SCL 6 4 GND SDA 5
Pin Description Pin# Pin Type Description
1 X1 I
Oscillator Circuit Input.
Together with X2, the 32.768kHz crystal is connected between them. 2 X2 O
Oscillator Circuit Output.
Together with X1, the 32.768kHz crystal is connected between them. 3 INT O
Interrupt Output.
Open drain, active low. 4 GND P
Ground.
5 SDA I/O
Serial Data Input/Output.
SDA is the input/output pin for the 2-wire serial interface. The SDA pin is open-drain output and requires an external pull-up resistor. 6 SCL I
Serial Clock Input.
SCL is used to synchronize data movement on the I2C serial interface. 7 SQW O
Clock Output.
Open drain. Four frequencies selectable: 32.768k, 1.024k, 32, 1Hz when SQWE bit is set to 1. 8 VCC P
Power.
