AD24C32 from IDCHIP, 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 address input bit 0. Tied to VCC or GND to set the lower three bits of the I2C slave address (fixed high nibble 1010, then A2 A1 A0). Allows up to 8 devices on one I2C bus.
2	A1	input	Device address input bit 1. Hardware-strapped to VCC or GND to form part of the I2C slave address.
3	A2	input	Device address input bit 2. Hardware-strapped to VCC or GND to form part of the I2C slave address.
4	GND	power_in	Ground / power negative reference. Common return for VCC and all I/O signals.
5	SDA	bidirectional	I2C serial data line. Open-drain bidirectional pin; requires an external pull-up resistor (typ. 10kΩ) to VCC. Data is stable when SCL is high.
6	SCL	input	I2C serial clock input, driven by the bus master. Requires an external pull-up resistor (typ. 10kΩ) to VCC. Supports up to 400kHz at 1.8V and up to 1MHz at 2.7V/5V.
7	WP	input	Hardware write protect input. When tied high (VCC), write operations to the EEPROM array are inhibited; when tied low (GND), normal read/write operation is allowed.
8	VCC	power_in	Positive supply input, 1.8V to 5.5V (absolute max 5.5V). A local 1µF decoupling capacitor to GND is recommended per the typical application circuit.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad24c32.step`	122 KB	You want the bare part, or you mark your own boards.
`ad24c32-etched.step`	1.6 MB	You want the part with `AD24C32` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 411 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.
