M24C16-RMN6TP from STMicroelectronics, 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	NC	unconnected	Not connected. Leave floating or tie to VSS; the pin has no internal bond.
2	NC	unconnected	Not connected. Leave floating or tie to VSS; the pin has no internal bond.
3	NC	unconnected	Not connected. Leave floating or tie to VSS; the pin has no internal bond.
4	VSS	power_in	Ground reference for the VCC supply. Connect to the board's 0 V rail.
5	SDA	bidirectional	I2C Serial Data line. Open-drain bidirectional I/O for transferring data in and out of the device; requires an external pull-up resistor to VCC (see Figure 11 for Rbus sizing).
6	SCL	input	I2C Serial Clock input. Strobes data available on SDA(in) and clocks data out on SDA(out). Compatible with 100 kHz and 400 kHz I2C modes.
7	WC	input	Active-low Write Control input. When driven high, write operations to the memory array are inhibited (device select and address bytes are still acknowledged, data bytes are not). When driven low or left floating, write operations are enabled.
8	VCC	power_in	Supply voltage input. M24C16-R operating range is 1.8 V to 5.5 V. Decouple to VSS with a 10 nF to 100 nF capacitor placed close to the pins.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24c16-rmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24c16-rmn6tp-etched.step`	2.3 MB	You want the part with `M24C16-RMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 577 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.
