PT7C4337WEX from Diodes Incorporated, in a SOIC-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 | input | Oscillator circuit input; together with X2, 32.768 kHz crystal is connected between them, or external clock input. |
| 2 | X2 | output | Oscillator circuit output; together with X1, 32.768 kHz crystal is connected between them; when 32.768 kHz external input, X2 must be left floating. |
| 3 | INTA | output | Interrupt output, open-drain; asserted low when time matches alarm 1 registers if alarm 1 is enabled; requires external pull-up resistor. |
| 4 | GND | power_in | Ground. |
| 5 | SDA | bidirectional | Serial data input/output, open-drain; 2-wire I2C serial interface; requires external pull-up resistor. |
| 6 | SCL | input | Serial clock input; used to synchronize data movement on I2C serial interface. |
| 7 | SQW/INTB | output | Square-wave or interrupt output, open-drain; programmable 1 Hz, 4.096 kHz, 8.192 kHz, or 32.768 kHz square-wave output, or interrupt signal; requires external pull-up resistor. |
| 8 | VCC | power_in | Primary power supply for PT7C4337; recommended operating range 1.8 V to 5.5 V. |
