FM24CL04B-GTR from Infineon, in a SOIC-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 connect. Not internally bonded; leave floating or tie as convenient for layout.
2	A1	input	Device Select Address 1. One of the device-select address inputs used to select one of up to 4 devices on the same I2C bus; must match the corresponding bit in the slave address. Internally pulled down.
3	A2	input	Device Select Address 2. One of the device-select address inputs used to select one of up to 4 devices on the same I2C bus; must match the corresponding bit in the slave address. Internally pulled down.
4	VSS	power_in	Ground for the device. Must be connected to the system ground.
5	SDA	bidirectional	Serial Data/Address. Bi-directional open-drain I2C data line; wire-AND'd with other devices on the bus. Input has a Schmitt trigger for noise immunity; output driver has slope control for falling edges. Requires an external pull-up resistor.
6	SCL	input	Serial Clock for the I2C interface. Data is clocked out on the falling edge and into the device on the rising edge. Input has a Schmitt trigger for noise immunity.
7	WP	input	Write Protect. When tied to VDD, the entire memory map is write-protected. When tied to ground, all addresses are write-enabled. Internally pulled down.
8	VDD	power_in	Power supply input, 2.7 V to 3.65 V operating range.
