24LC08BT-I/OT

Microchip · EEPROM · SOT-23-5

24LC08BT-I from Microchip, 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 A0 unconnected Not connected internally on the 24XX08. May be left floating or tied to VSS or VCC.
2 A1 unconnected Not connected internally on the 24XX08. May be left floating or tied to VSS or VCC.
3 A2 unconnected Not connected internally on the 24XX08. 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 bus. Open-drain bidirectional pin; requires an external pull-up to VCC (typ. 10 kΩ at 100 kHz, 2 kΩ at 400 kHz and 1 MHz). Schmitt-trigger input with noise suppression.
6 SCL input I2C serial clock input driven by the host, used to synchronize data transfers to and from the device. Schmitt-trigger input.
7 WP input Write-Protect input. Must be tied to VSS (normal read/write operation) or VCC (entire array 000-3FF write-protected; reads still allowed). Do not leave floating.
8 VCC power_in Positive supply. 2.5V-5.5V for 24LC08B (1.7V-5.5V for 24AA08/24FC08). Decouple to VSS with a local bypass capacitor.

CAD (KiCad official)

  • Symbol: 24LC08BT-I
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: 24lc08bt-i-etched.step / 24lc08bt-i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 24lc08bt-i.step / 24lc08bt-i.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
24lc08bt-i.step 85 KB You want the bare part, or you mark your own boards.
24lc08bt-i-etched.step 1.8 MB You want the part with 24LC08BT-I already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 449 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: Microchip datasheet (48 pp, sha256 033b0fb6a9be5ea4, 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).
