Slkor SLKORMICRO Elec · Real Time Clocks · SOP-8

SL8563T-G from Slkor SLKORMICRO Elec, 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 OSCI input Oscillator input for the external 32.768kHz crystal; the OSCI absolute input range is -0.5V to VDD+0.5V.
2 OSCO output Oscillator output for the external 32.768kHz crystal; see note 3 on page 16 for its use.
3 INT output Interrupt output for the alarm and periodic timer flags, with pulse or level behavior selected by TI/TP (register 01H); the absolute output voltage limit is -0.5V to +6.5V.
4 VSS power_in Ground reference for the device.
5 SDA bidirectional I2C serial data line; VIL is 0 to 0.3VDD and VIH is 0.7VDD to VDD, with absolute limits of -0.5V to +6.5V.
6 SCL input I2C serial clock input, up to 400kHz; absolute input limits are -0.5V to +6.5V.
7 CLKOUT output Programmable clock output selectable as 32.768kHz, 1024Hz, 32Hz or 1Hz via register 0DH and enabled by the FE bit; absolute output limits are -0.5V to +6.5V.
8 VDD power_in Supply voltage: 1.0V to 5.5V for I2C communication and 1.8V to 5.5V at 400kHz, with absolute limits of -0.5V to +6.5V.
