DS3232MZ+TRL from Analog Devices Inc Maxim Integrated, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 32KHZ | output | 32.768kHz push-pull output with 50% duty cycle, active on VCC when EN32KHZ = 1 and on VBAT when BB32KHZ = 1, forced low when disabled, and may be left unconnected if not used. |
| 2 | VCC | power_in | Primary power supply pin that should be decoupled using a 0.1µF to 1.0µF capacitor, and connected to ground if not used. |
| 3 | INT/SQW | output | Open-drain active-low interrupt or 1Hz square-wave output that requires an external pullup to a supply of 4.5V or less and may be left open if not used. |
| 4 | RST | bidirectional | Open-drain active-low reset input/output that indicates VCC status relative to VPF and doubles as a debounced pushbutton input, with an internal 50kΩ nominal pullup to VCC, so no external pullup should be connected. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | VBAT | power_in | Backup power-supply input that should be decoupled with a 0.1µF to 1.0µF low-leakage capacitor when used as the primary source, is not required when used as backup, and should be connected to ground if not used. |
| 7 | SDA | bidirectional | Open-drain I2C serial data input/output that requires an external pullup resistor, with the pullup voltage up to 4.5V regardless of the voltage on VCC. |
| 8 | SCL | input | I2C serial clock input that synchronizes data movement on the serial interface, with the pullup voltage up to 4.5V regardless of the voltage on VCC. |
