AT24C08D-STUM-T-TUDI from Tudi, in a SOT-23-5. 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	SCL	input	Serial clock input. Used to positive-edge clock data into the EEPROM and negative-edge clock data out. Schmitt-trigger filtered input; requires external pull-up per I2C spec.
2	GND	power_in	Ground reference (0 V) for the device.
3	SDA	bidirectional	Serial data, bi-directional, open-drain. May be wire-ORed with other open-drain/open-collector devices. Requires external pull-up resistor to VCC.
4	VCC	power_in	Supply voltage input, 1.7 V to 5.5 V. Typical read current 0.14 mA, write current 0.28 mA at 400 kHz / VCC=5.0V. Standby current 0.03 uA typ.
5	WP	input	Write Protect. Tie to GND for normal read/write operations; tie to VCC to enable hardware write protection over the full array.
