ZD24C32A-SSGMT from Zetta, in a SOIC-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	NC	unconnected	No Connect. Not bonded to a die pad. May be connected to GND or left floating.
2	NC	unconnected	No Connect. Not bonded to a die pad. May be connected to GND or left floating.
3	NC	unconnected	No Connect. Not bonded to a die pad. May be connected to GND or left floating.
4	GND	power_in	Ground reference for the power supply. Connect to system ground.
5	SDA	bidirectional	Serial Data. Open-drain bidirectional data line used to transfer data to/from the device. Requires an external pull-up resistor (not exceeding 10 kOhm) to VCC; may be wire-ORed with other open-drain devices on the same bus.
6	SCL	input	Serial Clock. Master-driven clock input; command/data on SDA is latched on the rising edge and output data is clocked out on the falling edge of SCL. Must be forced high or pulled high with an external resistor when the bus is idle.
7	WP	input	Write Protect. Active-high. Tie to GND for normal write operation; tie to VCC to inhibit all writes to the memory array. If left undriven, an internal weak pull-down biases the pin to GND but the datasheet recommends driving it to a known state.
8	VCC	power_in	Device power supply. VCC = 1.7V to 5.5V. Operation outside this range may produce spurious results and should not be attempted.
