AT24CM02-SSHD-B from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No connect pin with no internal function stated.
2	NC	unconnected	No connect pin with no internal function stated.
3	A2	input	Device address input, hard-wired to GND or VCC (up to two devices per bus); if not driven it is internally pulled down to GND, and connecting it to a known state is recommended (pull-up 10 kΩ or less).
4	GND	power_in	Ground reference for the power supply, to be connected to system ground.
5	SDA	bidirectional	Open-drain bidirectional serial data pin that requires an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices.
6	SCL	input	Serial clock input that controls data flow; input data is latched on the rising edge and output data is clocked out on the falling edge, and it must be forced high or pulled up when the bus is idle.
7	WP	input	Write-protect input: connected to GND allows normal writes, connected to VCC inhibits all writes to the full array; internally pulled down to GND if not driven.
8	VCC	power_in	Device power supply pin; the AT24CM02-SSHD variant operates from 2.5V to 5.5V.
