AT24HC02C-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	Device address input, hard-wired to GND or VCC to set the least-significant bit of the I2C slave address. Internally pulled down to GND if left floating; recommended external pull-up ≤ 10 kΩ.
2	A1	input	Device address input, hard-wired to GND or VCC to set the middle bit of the I2C slave address. Internally pulled down to GND if left floating; recommended external pull-up ≤ 10 kΩ.
3	A2	input	Device address input, hard-wired to GND or VCC to set the most-significant of the three cascade bits of the I2C slave address. Internally pulled down to GND if left floating; recommended external pull-up ≤ 10 kΩ.
4	GND	power_in	Ground reference for the power supply. Connect to system ground.
5	SDA	bidirectional	Serial data pin, open-drain bidirectional I/O for the I2C bus. Requires external pull-up (≤ 10 kΩ recommended) and may be wire-ORed with other open-drain devices on the same bus.
6	SCL	input	Serial clock input for the I2C bus. Data is latched on the rising edge and shifted out on the falling edge. Must be pulled high externally when the bus is idle.
7	WP	input	Write-Protect input. Tie to GND for normal write operations; tie to VCC to inhibit writes to the upper-half (1K) of the array. Internally pulled down to GND if left floating; recommended external pull-up ≤ 10 kΩ.
8	VCC	power_in	Device power supply, 1.7V to 5.5V operating range (6.25V absolute maximum). Bypass with a decoupling capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at24hc02c-sshm-t.step`	122 KB	You want the bare part, or you mark your own boards.
`at24hc02c-sshm-t-etched.step`	2.7 MB	You want the part with `AT24HC02C-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: 673 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.
