BL24C02F-PARC from BL Shanghai Belling, 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. Hard-wired to VCC or GND to set one of eight possible I2C device addresses (upper nibble 1010, followed by A2/A1/A0). Internally biased low if left floating.
2	A1	input	Device address input bit 1. Hard-wired to VCC or GND to help form the 7-bit I2C slave address. Internally biased low if left floating.
3	A2	input	Device address input bit 2. Hard-wired to VCC or GND to help form the 7-bit I2C slave address. Internally biased low if left floating.
4	GND	power_in	Ground reference for supply and I/O signals.
5	SDA	bidirectional	I2C serial data line. Open-drain bidirectional; requires an external pull-up resistor to VCC. May be wire-ORed with other open-drain/open-collector devices on the same bus.
6	SCL	input	I2C serial clock input. Data is latched into the EEPROM on the positive edge and clocked out on the negative edge. Schmitt-trigger, filtered input for noise suppression.
7	WP	input	Write Protect input. Tie to GND for normal read/write operation. Tie to VCC to hardware write-protect the full 2K memory array.
8	VCC	power_in	Positive supply voltage input. Single-supply operation; decouple to GND with a 100 nF ceramic capacitor close to the pin.

CAD (KiCad official)

3D model: SOP-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`bl24c02f-parc.step`	122 KB	You want the bare part, or you mark your own boards.
`bl24c02f-parc-etched.step`	2.4 MB	You want the part with `BL24C02F-PARC` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 602 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.
