24LC16BT-I from Microchip, in a SOIC-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 A0 unconnected Not connected internally on the 24XX16 (the 16 Kbit density uses the address bits as block-select bits inside the control byte instead of external address pins). May be left floating or tied to VSS or VCC.
2 A1 unconnected Not connected internally on the 24XX16. May be left floating or tied to VSS or VCC.
3 A2 unconnected Not connected internally on the 24XX16. May be left floating or tied to VSS or VCC.
4 VSS power_in Ground reference for the device (0 V).
5 SDA bidirectional Serial Address/Data I/O for the I2C interface. Open-drain output; requires an external pull-up to VCC (typically 10 kOhm at 100 kHz, 2 kOhm at 400 kHz). Schmitt-trigger input; VIH >= 0.7VCC, VIL <= 0.3VCC; VOL <= 0.4 V at IOL = 3 mA.
6 SCL input I2C serial clock input used to synchronize data transfer to and from the device. Schmitt-trigger input; supports 100 kHz and 400 kHz clock rates (400 kHz requires VCC >= 2.5V on the 24AA16).
7 WP input Write-Protect input. Tie to VSS to enable normal read/write operation across the full 000-7FF array; tie to VCC to write-protect the entire memory (read operations are unaffected). Must not be left floating.
8 VCC power_in Positive supply. +1.7V to 5.5V for 24AA16, +2.5V to 5.5V for 24LC16B. Typical operating current 1 mA (write) / 0.01 mA (read), standby ~1 uA.

CAD (KiCad official)

  • Symbol: 24LC16BT-I
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: 24lc16bt-i-etched.step / 24lc16bt-i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 24lc16bt-i.step / 24lc16bt-i.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
24lc16bt-i.step 122 KB You want the bare part, or you mark your own boards.
24lc16bt-i-etched.step 1.8 MB You want the part with 24LC16BT-I already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 453 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: Microchip datasheet (40 pp, sha256 28b29227a64b3e99, retrieved 2026-08-17, tier: manufacturer)
  • 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).
