24C16BN

XBLW · EEPROM · SOP-8

24C16BN 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 NC unconnected No connect. 24C16 does not use any device address pins, so on the 8-lead DIP/SOP/MSOP/TSSOP package pins 1-3 are unused and may be left floating or tied to GND.
2 NC unconnected No connect. Unused on the 8-lead SOP variant; leave floating or tie to GND.
3 NC unconnected No connect. Unused on the 8-lead SOP variant; leave floating or tie to GND.
4 GND power_in Ground reference for the device.
5 SDA bidirectional Serial data input / open-drain output for the two-wire (I2C-compatible) bus. Requires an external pull-up resistor to VCC (typ. 4.7 kOhm). Can be wire-ORed with other open-drain outputs. Schmitt-trigger filtered input.
6 SCL input Serial clock input for the two-wire (I2C-compatible) bus. Rising edge latches data into the EEPROM; falling edge clocks data out. Requires an external pull-up resistor to VCC. Bus rates up to 1 MHz (VCC >= 2.5 V) or 400 kHz (VCC = 1.8 V).
7 WP input Write Protect. Tie to VIL (or GND) to allow programming of the EEPROM array; tie to VIH (or VCC) to disable all write/programming operations. Read operations are unaffected. Internally recognized as VIL if left floating, but the datasheet recommends always driving WP to a known state (pull-up/down resistor <=10 kOhm) to avoid capacitive coupling issues.
8 VCC power_in Positive power supply, 1.8 V to 5.5 V. Standby current typically 0.02 uA @ 1.8 V and 0.06 uA @ 5.5 V. Decouple with a 0.1 uF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: 24C16BN
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: 24c16bn-etched.step / 24c16bn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 24c16bn.step / 24c16bn.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
24c16bn.step 122 KB You want the bare part, or you mark your own boards.
24c16bn-etched.step 1.6 MB You want the part with 24C16BN already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 404 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 cd886c4c7b15f274, 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).
