M24C16-WMN6TP 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. No internal bond; may be left floating or tied to VSS.
2	NC	unconnected	Not connected. No internal bond; may be left floating or tied to VSS.
3	NC	unconnected	Not connected. No internal bond; may be left floating or tied to VSS.
4	VSS	power_in	Ground. Reference for the VCC supply voltage.
5	SDA	bidirectional	I2C Serial Data (bidirectional, open-drain). Transfers data into and out of the device; must be pulled up to VCC via an external resistor. May be wire-OR'ed with other open-drain devices on the bus.
6	SCL	input	I2C Serial Clock input. Strobes data into SDA on writes and clocks data out on reads. Supports 100 kHz and 400 kHz I2C modes.
7	WC	input	Write Control input (active low). When driven high, writes to the entire memory array are inhibited (address/select bytes are still ACKed, but data bytes are not). When driven low or left floating, writes are enabled.
8	VCC	power_in	Supply voltage. M24C16-W: 2.5 V to 5.5 V; M24C16-R: 1.8 V to 5.5 V; M24C16-F: 1.7 V to 5.5 V (full temperature range). Decouple with a 10 nF to 100 nF capacitor close to the VCC/VSS pins.

CAD (KiCad official)

3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24c16-wmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24c16-wmn6tp-etched.step`	2.2 MB	You want the part with `M24C16-WMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 556 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.
