SL24C64D from Slkor SLKORMICRO Elec, 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 to VCC or GND to set one of the least significant bits of the I2C slave address, allowing up to 8 SL24C64 devices on the same bus.
2	A1	input	Device address input bit 1. Hard-wired to VCC or GND to select the I2C slave address. Combined with A0/A2, allows up to 8 devices per bus.
3	A2	input	Device address input bit 2. Hard-wired to VCC or GND to select the I2C slave address. Combined with A0/A1, allows up to 8 SL24C64 devices per bus.
4	GND	power_in	Ground reference (0 V) for the device.
5	SDA	bidirectional	Serial data input/output. Bidirectional open-drain I2C data line; requires an external pull-up resistor to VCC (typical 10 kΩ). Input capacitance ~8 pF.
6	SCL	input	Serial clock input. Synchronizes data transfer on SDA. Data is latched on the rising edge of SCL and shifted out on the falling edge. Max frequency 400 kHz at 1.8/2.5/2.7 V, 1 MHz at 5 V.
7	WP	input	Write-protect input. When tied to GND, normal read/write operations are allowed. When tied to VCC, the memory is write-protected (read-only).
8	VCC	power_in	Positive supply voltage, 1.8 V to 5.5 V. Typical operating current 1 mA, standby current 1 μA.
