AD24C02 from IDCHIP, in a SOT-23-5. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	A0	input	Device address input bit 0. Tied high or low to set bit1 of the 7-bit I2C slave address (device address high nibble is fixed 1010, followed by A2/A1/A0). Allows up to 8 AD24C02 devices on the same I2C bus.
2	A1	input	Device address input bit 1. Selects the I2C slave address together with A0 and A2.
3	A2	input	Device address input bit 2. Selects the I2C slave address together with A0 and A1.
4	GND	power_in	Ground / power negative reference.
5	SDA	bidirectional	I2C serial data line. Open-drain bidirectional data pin; requires an external pull-up resistor to VCC (typ. 10 kΩ).
6	SCL	input	I2C serial clock input. Drives the address/data timing; supports up to 400 kHz at 1.8V/2.5V/2.7V and 1 MHz at 5V. External pull-up to VCC required (typ. 10 kΩ).
7	WP	input	Hardware write-protect input. When tied high, memory-array writes are inhibited; when tied low (or left connected to GND), normal read/write operation is allowed.
8	VCC	power_in	Positive supply voltage, 1.8V to 5.5V (absolute max 5.5V). Recommend a 1 µF decoupling capacitor close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad24c02.step`	85 KB	You want the bare part, or you mark your own boards.
`ad24c02-etched.step`	1.5 MB	You want the part with `AD24C02` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 361 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.
