AT24C04CDGKRG from HANSCHIP semiconductor, 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	NC	unconnected	No internal connection on the SOP-8/DIP-8/MSOP-8 packages. Leave floating or tie to GND.
2	E1	input	Device Address Input bit 1. Hard-wired address bit that must match the E1 field in the I2C device address byte. Tie directly to VCC or GND; internally pulled down to GND if left floating.
3	E2	input	Device Address Input bit 2. Hard-wired address bit that must match the E2 field in the I2C device address byte. Tie directly to VCC or GND; 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 I2C data line for command, address, and data transfer. Requires an external pull-up resistor to VCC.
6	SCL	input	Serial Clock. I2C clock input driven by the bus master; data on SDA is latched on the rising edge and clocked out on the falling edge. Requires an external pull-up resistor to VCC.
7	WP	input	Write Protection. When tied to VCC the entire memory array 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 to GND with a local decoupling capacitor.
