24LC02BT-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	Address input pin - NOT USED by the 24XX02 (internal connection absent). May be left floating or tied to VSS or VCC. Present for pin compatibility with larger 24XX-family EEPROMs.
2	A1	unconnected	Address input pin - NOT USED by the 24XX02 (no internal connection). May be left floating or tied to VSS or VCC.
3	A2	unconnected	Address input pin - NOT USED by the 24XX02 (no internal connection). May be left floating or tied to VSS or VCC.
4	VSS	power_in	Ground reference for the device. Connect to system ground (0V).
5	SDA	bidirectional	Serial Address/Data I/O for the 2-wire I2C bus. Open-drain terminal; requires an external pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz). Data may only change while SCL is low.
6	SCL	input	Serial Clock input used to synchronize data transfer to and from the device. Schmitt-trigger input with noise filtering; supports 100 kHz and 400 kHz clock rates.
7	WP	input	Write-Protect input. Must be connected to VSS or VCC. Tied to VSS enables normal read/write; tied to VCC inhibits all write operations to the entire 00h-FFh array (reads remain unaffected).
8	VCC	power_in	Positive supply input. 2.5V to 5.5V for the 24LC02B (industrial and automotive grades). ICC(write) typ 0.1 mA / max 3 mA, ICC(read) typ 0.05 mA / max 1 mA, standby typ 10 nA.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24lc02bt-i.step`	122 KB	You want the bare part, or you mark your own boards.
`24lc02bt-i-etched.step`	1.9 MB	You want the part with `24LC02BT-I` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 474 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.
