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.

3D model downloads

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.
