HX24C64DRG from HANSCHIP semiconductor, 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	input	Device address input bit 0. Hard-wired by the user to set one of up to eight unique device addresses on a shared two-wire bus. Compared against A0 bit in the device address word.
2	A1	input	Device address input bit 1. Hard-wired to set part of the 3-bit device address that identifies this EEPROM on a multi-drop two-wire bus.
3	A2	input	Device address input bit 2. Hard-wired to set part of the 3-bit device address. Up to eight HX24C64 devices may share one two-wire bus.
4	GND	power_in	Ground reference for the device.
5	SDA	bidirectional	Serial Data. Bi-directional open-drain data line for the two-wire (I2C-compatible) interface; requires an external pull-up resistor to VCC. May be wire-ORed with other open-drain/open-collector devices on the bus. Input capacitance 8 pF typ.
6	SCL	input	Serial Clock Input. Positive edge clocks data into the EEPROM and negative edge clocks data out. Schmitt-trigger, filtered for noise suppression. Up to 1 MHz at 5V, 400 kHz at 1.8/2.5/2.7V.
7	WP	input	Write Protect. When tied to GND, normal read/write operations are allowed. When tied to VCC, the entire 64K array is write-protected in hardware.
8	VCC	power_in	Positive supply. Operating range 1.8V to 5.5V. Read Icc typ 0.4 mA, write Icc typ 2.0 mA at 5V/100 kHz; standby current 2 µA max.
