HG24LC08M from HGSEMI, 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	No connect on the HG24LC08. On the 8K variant this device-address input is unused (the corresponding address bit is used internally for page addressing); tie to GND for compatibility.
2	A1	unconnected	No connect on the HG24LC08. On the 8K variant this device-address input is unused (the corresponding address bit is used internally for page addressing); tie to GND for compatibility.
3	A2	input	Device-address input for the HG24LC08. Sets the hard-wired A2 bit compared against the device-address byte; up to two 8K devices per bus. Schmitt-triggered CMOS input.
4	GND	power_in	Ground reference for the device.
5	SDA	bidirectional	Bidirectional I2C serial data line, open-drain. Requires external pull-up to VCC. Compatible with 1 MHz (5 V) and 400 kHz (1.8/2.5/2.7 V) bus rates.
6	SCL	input	I2C serial clock input. Positive edge clocks data into the EEPROM, negative edge clocks data out. Schmitt-triggered.
7	WP	input	Write-protect input. Tie to GND for normal read/write; tie to VCC to write-protect the entire 8K array. Schmitt-triggered.
8	VCC	power_in	Supply voltage input. Operating range 1.7 V to 5.5 V. Recommend a 100 nF decoupling capacitor to GND close to the pin.
