FM24C04B-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. Pin is not internally bonded and should be left floating or tied to VSS.
2	A1	input	Device select address bit 1. Sets the lower device address bit compared with the slave-address byte on the two-wire bus. Internally pulled down (~1 MΩ weak, 40 kΩ strong pull-down when input is low).
3	A2	input	Device select address bit 2. Sets the upper device address bit compared with the slave-address byte on the two-wire bus. Internally pulled down.
4	VSS	power_in	Ground reference for the device (0 V).
5	SDA	bidirectional	Serial Data/Address (I2C). Bi-directional open-drain data line for the two-wire interface; Schmitt-trigger input with slope-controlled output for falling edges. External pull-up resistor to VDD is required (Rmin = 1.8 kΩ).
6	SCL	input	Serial Clock input for the two-wire interface. Data is clocked out of the device on the SCL falling edge and clocked in on the rising edge. Schmitt-trigger input; supports up to 1 MHz.
7	WP	input	Write Protect. When high, the entire array is write-protected; when low, all addresses may be written. Internally pulled down; tie to VSS to enable writes.
8	VDD	power_in	Main power supply, 4.5 V to 5.5 V (5.0 V typ). Active current 100 µA @ 100 kHz SCL; standby current 4 µA typ.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fm24c04b-gtr.step`	122 KB	You want the bare part, or you mark your own boards.
`fm24c04b-gtr-etched.step`	2.2 MB	You want the part with `FM24C04B-GTR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 568 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
