AT24C16DGKRG from HANSCHIP semiconductor, in a MSOP-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	unconnected	On the AT24C16, the device address input A0 is a No Connect and may be tied to GND. It is not used for hardware device addressing on the 16K variant (whole address space is used for memory page selection).
2	A1	unconnected	On the AT24C16, the device address input A1 is a No Connect and may be tied to GND. Not used for hardware device addressing on the 16K variant.
3	A2	unconnected	On the AT24C16, the device address input A2 is a No Connect and may be tied to GND. Not used for hardware device addressing on the 16K variant.
4	GND	power_in	Ground reference for the device (0 V).
5	SDA	bidirectional	Two-wire serial data line. Open-drain, bi-directional; must be tied to VCC through an external pull-up resistor. May be wire-ORed with any number of other open-drain / open-collector devices on the same bus.
6	SCL	input	Two-wire serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Compatible with 1 MHz (at 5V) and 400 kHz (at 1.8/2.5/2.7V) bus speeds.
7	WP	input	Hardware Write Protect input. Tie to GND for normal read/write operations. Tie to VCC to enable write protection of the full 16K array (see Table 2).
8	VCC	power_in	Positive supply voltage input. Operating range 1.7 V to 5.5 V. Decouple to GND with a local bypass capacitor.
