24C64S

XBLW · EEPROM · SOT-23-5

24C64S from XBLW, in a SOT-23-5. 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 SCL input Serial clock input for the 2-wire bus. Rising edge latches data into the EEPROM; falling edge clocks data out. Requires an external pull-up resistor (typ. 4.7 kΩ to VCC).
2 GND power_in Ground / device 0 V reference.
3 SDA bidirectional Serial data line, bi-directional open-drain. Can be wire-OR'd with other open-drain devices. Requires an external pull-up resistor (typ. 4.7 kΩ to VCC).
4 VCC power_in Positive supply, 1.8 V to 5.5 V. Decouple locally with a 100 nF ceramic capacitor to GND.
5 WP input Write-Protect input. Tie to GND (or leave open - internally pulled to VIL) to allow programming; tie to VCC / VIH to disable all write operations. Read operations are unaffected by WP state.

CAD (KiCad official)

  • Symbol: 24C64S
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: 24c64s-etched.step / 24c64s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 24c64s.step / 24c64s.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
24c64s.step 85 KB You want the bare part, or you mark your own boards.
24c64s-etched.step 1.4 MB You want the part with 24C64S already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 349 faces against 102 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 (18 pp, sha256 c0329401d1e9b2e0, 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).
