ZD24C08AE1-STGMT from Zetta, 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	NC	unconnected	No Connect. Pin is not bonded to a die pad. May be tied to GND or left floating.
2	NC	unconnected	No Connect. Pin is not bonded to a die pad. May be tied to GND or left floating.
3	A2	input	Device Address Input. Selects the hardware device address bit A2 for the I2C slave address. Tie to VCC or GND; if left undriven it is internally weakly pulled down to GND (pull-down disengages once biased above ~0.5 x VCC). Zetta recommends driving to a known state.
4	GND	power_in	Ground reference for the power supply. Connect to system ground.
5	SDA	bidirectional	Serial Data. Open-drain bidirectional I2C data line for serial data transfer. Requires an external pull-up resistor (not to exceed 10 kΩ) to VCC and may be wire-ORed with other open-drain/open-collector devices on the bus.
6	SCL	input	Serial Clock. Clock input from the I2C master used to strobe data on the SDA line; SDA is latched on rising edge and clocked out on falling edge of SCL. Must be forced high when the bus is idle or pulled high via an external pull-up resistor.
7	WP	input	Write Protect. Tie to GND for normal write operations; tie to VCC to inhibit all writes (full-array protection). Asserted high. Internally weakly pulled down to GND when undriven; Zetta recommends driving to a known state.
8	VCC	power_in	Device Power Supply. Provides the source voltage to the device; operation at invalid VCC levels may produce spurious results.
