FM24CL64B-GTR from Infineon, in a SOIC-8-150mil. 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 Select Address bit 0. One of three slave-address select pins used to select one of up to 8 devices on the same I2C bus. Internally pulled down.
2	A1	input	Device Select Address bit 1. One of three slave-address select pins used to select one of up to 8 devices on the same I2C bus. Internally pulled down.
3	A2	input	Device Select Address bit 2. One of three slave-address select pins used to select one of up to 8 devices on the same I2C bus. Internally pulled down.
4	VSS	power_in	Ground reference for the device. Must be connected to system ground (0 V).
5	SDA	bidirectional	I2C Serial Data / Address. Bi-directional, open-drain pin wire-AND'd with other devices on the I2C bus. Requires an external pull-up resistor to VDD. Input buffer has a Schmitt trigger; output driver includes slope control on falling edges.
6	SCL	input	I2C Serial Clock input. Data is clocked out of the device on the falling edge and into the device on the rising edge. Schmitt-trigger input for noise immunity. Supports up to 1 MHz operation.
7	WP	input	Write Protect. When tied to VDD, the entire memory map is write-protected. When tied to VSS, all addresses are write-enabled. Internally pulled down.
8	VDD	power_in	Power supply input. Operating range 2.7 V to 3.65 V. Bypass with a local decoupling capacitor to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fm24cl64b-gtr.step`	122 KB	You want the bare part, or you mark your own boards.
`fm24cl64b-gtr-etched.step`	2.3 MB	You want the part with `FM24CL64B-GTR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 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.
