M24C32-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 bit 0. Sets b1 of the 7-bit I2C device select code so up to 8 devices can share a bus. Must be tied to VCC or VSS; if left floating, is read as 0.
2	E1	input	Chip Enable address input bit 1. Sets b2 of the 7-bit I2C device select code. Must be tied to VCC or VSS; if left floating, is read as 0.
3	E2	input	Chip Enable address input bit 2. Sets b3 of the 7-bit I2C device select code. Must be tied to VCC or VSS; if left floating, is read as 0.
4	VSS	power_in	Ground reference for VCC supply voltage.
5	SDA	bidirectional	Serial Data. Bidirectional open-drain I2C data line used to transfer data in/out of the device; requires an external pull-up resistor to VCC.
6	SCL	input	Serial Clock. I2C clock input used to strobe data on SDA(in) and to output data on SDA(out). Supports 100 kHz, 400 kHz, and 1 MHz modes.
7	WC	input	Write Control (active low). When driven high, write operations to the entire memory array are inhibited (device select and address bytes are still acknowledged, but data bytes are not). Writes are enabled when WC is low or left floating.
8	VCC	power_in	Supply voltage. M24C32-R voltage range: 1.8 V to 5.5 V. Decouple with a 10 nF to 100 nF capacitor between VCC and VSS close to the device.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24c32-rmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24c32-rmn6tp-etched.step`	2.4 MB	You want the part with `M24C32-RMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 604 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.
