BL24C08F-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	NC	unconnected	No connect. Not internally bonded; leave floating or tie to GND.
2	NC	unconnected	No connect. Not internally bonded; leave floating or tie to GND.
3	A2	input	Device address input, hard-wired. Used together with the fixed 1010b prefix and P1/P0 memory-page bits to allow up to two 8K devices on one I2C bus. Internal weak bias pulls this pin to logic low when left floating.
4	GND	power_in	Ground reference. 0V return for VCC and all logic signals.
5	SDA	bidirectional	I2C serial data, bidirectional, open-drain. Requires an external pull-up resistor to VCC. May be wire-ORed with other open-drain devices on the bus. Input capacitance approx 8 pF.
6	SCL	input	I2C serial clock input. Positive edge clocks data in, negative edge clocks data out. Max 400 kHz at VCC 1.7-2.5V, 1 MHz at VCC 2.5-5.5V. Input capacitance approx 6 pF.
7	WP	input	Write Protect. Tie to GND for normal read/write operation. Tie to VCC to hardware-write-protect the full memory array.
8	VCC	power_in	Power supply, 1.7V to 5.5V. Typical read current 0.26 mA and write current 0.28 mA at 5.0V/400kHz; standby current 30 nA typ.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`bl24c08f-parc.step`	122 KB	You want the bare part, or you mark your own boards.
`bl24c08f-parc-etched.step`	2.5 MB	You want the part with `BL24C08F-PARC` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 626 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.
