# IN1363DT

**IKSEMICON** · Real Time Clocks · SOP-8

IN1363DT from IKSEMICON, 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 | passive | Connection for the 32.768 kHz quartz resonator (internal oscillator load 12 pF), and the input for an external 32.768 kHz oscillator when one is used. |
| 2 | OSCO | passive | Connection for the 32.768 kHz quartz resonator; left unconnected when OSCI is driven by an external oscillator. |
| 3 | INT | output | Interrupt output that goes low on alarm or timer events, either as a continuous or pulsed signal depending on the TI/TP bit; absolute maximum output voltage is -0.5 to 6.5 V and low-level output current is at least 1 mA at VOL = 0.4 V. |
| 4 | VSS | power_in | Common (ground) pin to which all voltages are referenced. |
| 5 | SDA | bidirectional | Serial data input/output of the double-wire bus; open-drain, so an external pull-up resistor is required, with at least 3 mA low-level output current at VOL = 0.4 V. |
| 6 | SCL | input | Serial clock input that synchronises data transfer on the double-wire bus at up to 400 kHz; high level is 0.7VDD minimum and low level is 0.3VDD maximum. |
| 7 | CLKOUT | output | Orthogonal frequency output (32.768 kHz, 8.192 kHz, 4.096 kHz or 1 Hz) enabled by the FE bit; open-drain, so an external pull-up resistor is required, with at least 1 mA low-level output current at VOL = 0.4 V. |
| 8 | VDD | power_in | Positive supply pin: 1.8 V to 5.5 V for bus-active operation at 400 kHz (1.0 V to 5.5 V in non-active mode), with bus access not guaranteed below 1.8 V. |

## CAD (KiCad official)

- Symbol: `IN1363DT`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `in1363dt-etched.step` / `in1363dt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `in1363dt.step` / `in1363dt.glb` are the bare package body.
