24AA02E48T-I from Microchip, in a SOT-23-5. 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	unconnected	Chip Address Input. Not used on the 24AA02E48/24AA02E64 (this variant); the pin may be left floating or tied to Vss or Vcc.
2	A1	unconnected	Chip Address Input. Not used on the 24AA02E48/24AA02E64; may be left floating or tied to Vss or Vcc.
3	A2	unconnected	Chip Address Input. Not used on the 24AA02E48/24AA02E64; may be left floating or tied to Vss or Vcc.
4	Vss	power_in	Ground reference.
5	SDA	bidirectional	Serial Address/Data I/O. Bidirectional open-drain pin used to clock addresses and data into and out of the device; requires an external pull-up to Vcc (typ 10 kΩ at 100 kHz, 2 kΩ at 400 kHz). Schmitt-trigger input with 50 ns spike filter.
6	SCL	input	Serial Clock input, used to synchronize data transfer to and from the device. Schmitt-trigger input; VIH ≥ 0.7·Vcc, VIL ≤ 0.3·Vcc.
7	NC	unconnected	No internal connection.
8	Vcc	power_in	Positive supply, +1.7 V to +5.5 V. Icc(write) 3 mA max, Icc(read) 1 mA max, Iccs (standby) 1 µA max (I-temp).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24aa02e48t-i.step`	85 KB	You want the bare part, or you mark your own boards.
`24aa02e48t-i-etched.step`	1.9 MB	You want the part with `24AA02E48T-I` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 492 faces against 102 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.
