M24512-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	E0	input	Chip Enable address input bit 0. Sets bit b1 of the 7-bit I2C device select code. Must be tied to VCC or VSS; reads as 0 if left floating.
2	E1	input	Chip Enable address input bit 1. Sets bit b2 of the 7-bit I2C device select code. Must be tied to VCC or VSS; reads as 0 if left floating.
3	E2	input	Chip Enable address input bit 2. Sets bit b3 of the 7-bit I2C device select code. Must be tied to VCC or VSS; reads as 0 if left floating.
4	VSS	power_in	Ground reference for the VCC supply voltage.
5	SDA	bidirectional	Serial Data input/output for the I2C bus. Open-drain output, requires a pull-up resistor to VCC. Wire-OR compatible with other open-drain / open-collector signals on the bus.
6	SCL	input	Serial Clock input for the I2C bus. Strobes data on SDA(in) and clocks data out on SDA(out).
7	WC	input	Write Control (active low, WC). When driven high, writes to the entire memory array are inhibited (device select and address bytes are still ACKed, data bytes are not). When driven low or left floating, writes are enabled.
8	VCC	power_in	Supply voltage. M24512-W: 2.5 V to 5.5 V; M24512-R / M24512-DR: 1.8 V to 5.5 V; M24512-DF: 1.7 V to 5.5 V. Decouple to VSS with a 10 nF to 100 nF capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24512-wmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24512-wmn6tp-etched.step`	2.2 MB	You want the part with `M24512-WMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 555 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.
