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. |
