FM24C16D-SO-T-G from FUDAN MICRO, in a SOP-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	Not Connected. Per the FM24C16D pin configuration table, address pins A0-A2 are internally not connected; the 16K device uses page-address bits inside the device-address byte instead of external address strapping.
2	A1	unconnected	Not Connected. Address pin retained for pinout compatibility with lower-density 24Cxx EEPROMs but internally unused on the 16Kbit variant.
3	A2	unconnected	Not Connected. Address pin retained for pinout compatibility with lower-density 24Cxx EEPROMs but internally unused on the 16Kbit variant.
4	GND	power_in	Ground reference for the device. Connect to the system 0V rail.
5	SDA	bidirectional	I2C Serial Data. Bidirectional, open-drain; requires an external pull-up resistor to VCC. May be wire-ORed with any number of other open-drain devices on the bus. VOL <= 0.4V at IOL = 2.1mA (VCC = 3.0V).
6	SCL	input	I2C Serial Clock input. Data is clocked into the EEPROM on the positive edge and out on the negative edge. Supports 400 kHz (1.7V-5.5V) and 1 MHz (2.5V-5.5V).
7	WP	input	Write Protect. WP tied to GND enables normal read/write operations; WP tied to VCC inhibits all writes to the full 16K array. If left floating with <3pF coupling to VCC plane, the pin is internally pulled to GND; >3pF coupling requires an explicit connection to GND.
8	VCC	power_in	Positive supply, 1.7V to 5.5V (2.5V to 5.5V for 1 MHz operation). Typical ICC = 0.4 mA read / 2.0 mA write at 400 kHz, 5.0V; standby current up to 6 uA. Absolute maximum 6.25V.
