AT24C02D-SSHM-T from Microchip, 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	A0	input	Hardware slave address input bit 0. Tied to VCC or GND to select one of eight device addresses on the I2C bus (forms the least-significant hardware address bit of the 7-bit slave address). Internally weakly pulled to GND when left floating; Atmel recommends driving to a defined level. CMOS input, trip point ~0.5 x VCC.
2	A1	input	Hardware slave address input bit 1. Sets bit A1 of the 7-bit I2C slave address so up to eight devices can share one bus. Internally weakly pulled to GND if left floating; connect to VCC or GND for a defined state.
3	A2	input	Hardware slave address input bit 2 (MSB of the three hardware address bits). Tie to VCC or GND to select one of eight device addresses on the shared I2C bus. Weak internal pull-down to GND if left unconnected.
4	GND	power_in	Ground reference for the device. Must be connected to the system ground.
5	SDA	bidirectional	I2C serial data. Open-drain bidirectional pin; requires an external pull-up resistor (not to exceed 10 kOhm) to VCC. May be wire-ORed with other open-drain / open-collector devices on the same bus. Data is latched into the device on the rising edge of SCL and driven out on the falling edge.
6	SCL	input	I2C serial clock input from the bus master. Must be pulled high through an external pull-up resistor or driven high when the bus is idle. Command and data present on SDA are latched in on the rising edge of SCL; output data on SDA is clocked out on the falling edge. Supports 400 kHz at 1.7V and 1 MHz at 2.5V.
7	WP	input	Write Protect. Tie to GND for normal write operations; tie to VCC to inhibit all write operations to the memory array (asserted high). Internally weakly pulled to GND if left floating; Atmel recommends driving to a known state.
8	VCC	power_in	Device power supply, 1.7V to 3.6V. Operation at invalid VCC voltages may produce spurious results and should not be attempted. Decouple to GND with a local bypass capacitor (typ. 100 nF).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at24c02d-sshm-t.step`	122 KB	You want the bare part, or you mark your own boards.
`at24c02d-sshm-t-etched.step`	2.6 MB	You want the part with `AT24C02D-SSHM-T` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 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.
