HG24C02CMM from HGSEMI, 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	E0	input	Device address input bit 0. Hard-wired to VCC or GND to set the chip's I2C slave address, allowing up to eight devices on the same bus. Internally pulled down to GND if left floating.
2	E1	input	Device address input bit 1. Hard-wired to VCC or GND to set the chip's I2C slave address. Internally pulled down to GND if left floating.
3	E2	input	Device address input bit 2. Hard-wired to VCC or GND to set the chip's I2C slave address. Internally pulled down to GND if left floating.
4	GND	power_in	Ground reference for the power supply. Connect to system ground.
5	SDA	bidirectional	Serial Data. Open-drain bidirectional I/O used to serially transfer data to and from the device. Requires an external pull-up resistor to VCC. Data is latched on the rising edge of SCL and clocked out on the falling edge.
6	SCL	input	Serial Clock input. Provides the clock that controls data flow to and from the device. Command and input data on SDA are latched on the rising edge of SCL; output data on SDA is clocked out on the falling edge.
7	WP	input	Write Protect input. When tied to VCC the entire memory array (including the Identification Page) becomes Read-only; when tied to GND write operations are enabled. Internally pulled down to GND if left floating.
8	VCC	power_in	Device power supply, 1.7 V to 5.5 V. Bypass with a local decoupling capacitor to GND. Operation at invalid VCC voltages may produce spurious results.
