M24C64-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. Left floating it is read as 0.
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. Left floating it is read as 0.
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. Left floating it is read as 0.
4	VSS	power_in	Ground reference for the VCC supply voltage.
5	SDA	bidirectional	I2C serial data input/output. Open-drain output; requires an external pull-up resistor to VCC. Transfers device select code, address bytes, and data bytes in and out of the EEPROM.
6	SCL	input	I2C serial clock input. Strobes the data available on SDA (input) and clocks the data driven on SDA (output).
7	WC	input	Write control (active-low, /WC). Driving this pin high inhibits all write operations to the memory array (data bytes are not acknowledged). Driving low or leaving floating enables writes.
8	VCC	power_in	Positive supply voltage. Range depends on variant: 2.5-5.5 V (M24C64-W), 1.8-5.5 V (M24C64-R), 1.7-5.5 V (M24C64-F/-DF). Decouple with 10-100 nF close to the VCC/VSS pins.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24c64-wmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24c64-wmn6tp-etched.step`	2.2 MB	You want the part with `M24C64-WMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 563 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.
