M24512-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	E0	input	Chip Enable address input, LSB of the device select (b1). Must be tied to VCC or VSS; when left floating it is read as 0. Sets one of the eight possible I2C slave addresses.
2	E1	input	Chip Enable address input (b2 of device select code). Must be tied to VCC or VSS; floating is read as 0.
3	E2	input	Chip Enable address input, MSB of the chip-select bits (b3). Must be tied to VCC or VSS; floating is read as 0.
4	VSS	power_in	Ground reference for VCC supply and all I/O signals.
5	SDA	bidirectional	I2C serial data, bidirectional open-drain. Requires an external pull-up resistor to VCC. Data is clocked on SCL.
6	SCL	input	I2C serial clock input. Strobes data on SDA (in and out). Supports 100 kHz / 400 kHz / 1 MHz bus modes.
7	WC	input	Write Control, active-low. When WC is driven high the entire memory array is write-protected (data bytes are not acknowledged). Drive low or leave floating to enable writes.
8	VCC	power_in	Supply voltage. M24512-R operating range 1.8 V to 5.5 V. Decouple with a 10-100 nF capacitor close to the VCC/VSS pins.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24512-rmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24512-rmn6tp-etched.step`	2.3 MB	You want the part with `M24512-RMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 576 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.
