DS1307CDRG 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 12.5pF load capacitance, or external oscillator input. |
| 2 | X2 | passive | 32.768 kHz crystal oscillator output pin with 12.5pF load capacitance, or left floating for external oscillator. |
| 3 | VBAT | power_in | +3V battery input, 2.0V to 3.5V operating range, supports 48mAhr+ lithium battery for over ten years at 25°C without main power. |
| 4 | GND | power_in | Ground/common connection. |
| 5 | SDA | bidirectional | Serial data input/output for I2C interface, open-drain output requiring external pull-up resistor. |
| 6 | SCL | input | Serial clock input for I2C interface, open-drain output with pull-up resistor. |
| 7 | SQW/OUT | output | Square wave output driver at 1Hz, 4.096kHz, 8.192kHz or 32.768kHz, open-drain requiring external pull-up resistor. |
| 8 | VCC | power_in | +5V power supply input pin with 4.5V to 5.5V operating range. |
