PCF8563DTR

XBLW · Real-time Clocks (RTC) · SOP-8

PCF8563DTR from XBLW, in a SOP-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 OSCI input Oscillator input. Connect to one terminal of the 32.768 kHz quartz crystal (Rs ≤ 40 kΩ, CL ≈ 10 pF). Integrated internal oscillator load capacitance (CINT ≈ 25 pF typ).
2 OSCO output Oscillator output. Connect to the other terminal of the 32.768 kHz quartz crystal, forming the timekeeping oscillator with OSCI.
3 INT output Open-drain, active-low interrupt output. Asserted by alarm and timer events; requires an external pull-up. IOL ≥ 1 mA at VOL = 0.4 V (VDD = 5 V).
4 VSS power_in Ground / negative supply reference (0 V).
5 SDA bidirectional I2C serial data line (open-drain). Requires external pull-up to VDD. Slave address: read 0xA3, write 0xA2. Max bus speed 400 kHz.
6 SCL input I2C serial clock input, up to 400 kHz. Driven by the I2C bus master; requires external pull-up to VDD.
7 CLKOUT output Programmable clock output (open-drain). Selectable frequency of 32.768 kHz, 1024 Hz, 32 Hz, or 1 Hz; 50% duty. Requires external pull-up.
8 VDD power_in Positive supply, 2.5 V to 5.5 V operating. Sleep current ~0.25 µA typ at VDD = 3.0 V, TA = 25 °C. Absolute max 6.5 V.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: PCF8563DTR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: pcf8563dtr-etched.step / pcf8563dtr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pcf8563dtr.step / pcf8563dtr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
pcf8563dtr.step 122 KB You want the bare part, or you mark your own boards.
pcf8563dtr-etched.step 2.3 MB You want the part with PCF8563DTR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 561 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: XBLW datasheet (20 pp, sha256 6c61c5a0ab6e34d8, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
