SD3010

WAVE · Real-Time Clocks (RTC) · SOP-8

SD3010 from WAVE, in a SOP-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 NC unconnected No connection; the datasheet pin drawing labels pin 1 as NC.
2 NC unconnected No connection; the datasheet pin drawing labels pin 2 as NC.
3 NC unconnected No connection; the datasheet pin drawing labels pin 3 as NC.
4 GND power_in Negative supply (ground).
5 SDA bidirectional Serial data input/output with an N-channel open-drain output and CMOS input; normally pulled up to VDD with a resistor and wire-ANDed with other open-drain devices.
6 SCL input Serial clock CMOS input; signals are processed on SCL rising/falling edges so rise/fall times must meet the datasheet, and the MCU port should be a CMOS output rather than open-drain.
7 INT output N-channel open-drain alarm/interrupt output whose mode is set by the control registers and which can be disabled by rewriting them.
8 VDD power_in Positive power supply, 1.8V to 5.5V.
