M24C08-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	NC	unconnected	Not connected. Internally unused in the 8-pin SO8/TSSOP8/PDIP8 packages of M24C08.
2	NC	unconnected	Not connected. Internally unused in the 8-pin SO8/TSSOP8/PDIP8 packages of M24C08.
3	E2	input	Chip Enable address input. Sets the value of bit b3 of the device select code (I2C slave address). Must be tied to VCC or VSS to establish the device address; if left floating it is read as 0. Allows up to two M24C08 devices to share the same I2C bus.
4	VSS	power_in	Ground reference for the VCC supply.
5	SDA	bidirectional	I2C serial data input/output. SDA(out) is an open-drain output that may be wire-OR'ed with other open-drain signals on the bus. Requires an external pull-up resistor to VCC (see Figure 13 for Rbus sizing versus bus capacitance at 400 kHz).
6	SCL	input	I2C serial clock input. Strobes data available on SDA (in) and clocks data out on SDA (out). Supports Standard-mode (100 kHz) and Fast-mode (400 kHz) I2C.
7	WC	input	Write Control (active-low, /WC). When driven high, write operations to the entire memory array are inhibited: device select and address bytes are acknowledged but data bytes are not. Write operations are enabled when /WC is driven low or left floating.
8	VCC	power_in	Positive supply voltage. For the -R variant (M24C08-RMN6TP) the operating range is 1.8 V to 5.5 V. Decouple with 10 nF to 100 nF close to the VCC/VSS pins.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`m24c08-rmn6tp.step`	122 KB	You want the bare part, or you mark your own boards.
`m24c08-rmn6tp-etched.step`	2.5 MB	You want the part with `M24C08-RMN6TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 622 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.
