DS1307IDRG

HANSCHIP semiconductor · Real Time Clocks · SOP-8

DS1307IDRG from HANSCHIP semiconductor, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 X1 passive 32.768 kHz crystal oscillator input pin with internal load capacitance of 12.5 pF.
2 X2 passive 32.768 kHz crystal oscillator output pin; can be left floating when using external oscillator signal on X1.
3 VBAT power_in +3V battery backup input with operating range 2.0V to 3.5V; provides backup power when VCC drops below VBAT threshold.
4 GND power_in Ground reference pin.
5 SDA bidirectional Serial data input/output line for I2C serial interface; open-drain output requiring external pull-up resistor.
6 SCL bidirectional Serial clock line for I2C serial interface; open-drain output requiring external pull-up resistor.
7 SQW/OUT output Square wave or static output driver pin with open-drain output; generates 1 Hz, 4.096 kHz, 8.192 kHz, or 32.768 kHz square wave when enabled, or fixed logic level when disabled.
8 VCC power_in +5V power supply input with operating range 4.5V to 5.5V for normal operation and data read/write capability.
