FT24C64A-TSR-T from FMD Fremont Micro Devices, 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/chip select address input bit 0. Hardwired to VIH or VIL to set one of the three lower bits of the I2C slave address (compared against bits 5-7 of the device address byte). Internally biased to VIL if left unconnected.
2	A1	input	Device/chip select address input bit 1. Hardwired to VIH or VIL to set the I2C slave address. Internally recognized as VIL if left unconnected.
3	A2	input	Device/chip select address input bit 2. Hardwired to VIH or VIL to set the I2C slave address. Internally recognized as VIL if left unconnected.
4	GND	power_in	Ground / device return. 0 V reference for VCC and all logic signals.
5	SDA	bidirectional	Serial data line for the two-wire (I2C-compatible) interface. Open-drain output; requires an external pull-up resistor to VCC (typ. 1.3 kΩ to 10 kΩ). Can be wire-OR'd with other open-drain devices on the same bus.
6	SCL	input	Serial clock input for the two-wire interface. Rising edge latches SDA data into the device; falling edge clocks data out. Schmitt-trigger, filtered input; requires an external pull-up to VCC.
7	WP	input	Write Protect input. Tie to GND (VIL) or leave unconnected to allow programming of the whole EEPROM array; tie to VIH/VCC to hardware-lock all write operations. Read operations are unaffected by WP.
8	VCC	power_in	Supply voltage, 1.7 V to 5.5 V. Must ramp monotonically at 0.1 V/ms to 50 V/ms during power-up. Decouple with a capacitor no smaller than 10 nF close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ft24c64a-tsr-t.step`	122 KB	You want the bare part, or you mark your own boards.
`ft24c64a-tsr-t-etched.step`	2.2 MB	You want the part with `FT24C64A-TSR-T` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 570 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.
