AT24C02C-SSHM-T from Microchip Tech, 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 bit 0. Hard-wired to VCC or GND to set the lower bit of the 7-bit I2C device address, allowing up to eight AT24C02C devices on a single 2-wire bus. Schmitt-trigger, filtered input.
2	A1	input	Device address input bit 1. Hard-wired to VCC or GND to set the middle bit of the 7-bit I2C device address. Schmitt-trigger, filtered input.
3	A2	input	Device address input bit 2. Hard-wired to VCC or GND to set the upper bit of the 7-bit I2C device address. Schmitt-trigger, filtered input.
4	GND	power_in	Ground reference (0 V) for the device supply and all logic-level signals.
5	SDA	bidirectional	I2C serial data. Open-drain, bidirectional pin used for serial data transfer; must be pulled up externally and may be wire-ORed with any number of other open-drain / open-collector devices on the 2-wire bus.
6	SCL	input	I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Supports 400 kHz at VCC = 1.7V and up to 1 MHz at VCC = 2.5V/2.7V/5.0V. Schmitt-trigger, filtered input.
7	WP	input	Write Protect. When tied to VCC the full array is write-protected (hardware data protection); when tied to GND normal read/write operations are enabled. Schmitt-trigger, filtered input.
8	VCC	power_in	Positive supply voltage, 1.7 V to 5.5 V. Typical read supply current 0.4 mA and write supply current 2.0 mA at VCC = 5.0 V, 400 kHz. Absolute max 6.25 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at24c02c-sshm-t.step`	122 KB	You want the bare part, or you mark your own boards.
`at24c02c-sshm-t-etched.step`	2.6 MB	You want the part with `AT24C02C-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: 646 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.
