24C02BN from XBLW 24C02BN XBLW, 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. Hardwired to VIH or VIL to set the chip select address (up to 8 devices on one I2C bus). If left unconnected it is internally recognized as VIL, but a pull-up/pull-down of 10 kΩ or less to a known state is recommended.
2	A1	input	Device address input bit 1. Hardwired to VIH or VIL to set the chip select address. Internally recognized as VIL if floating; 10 kΩ or less pull to a known state is recommended.
3	A2	input	Device address input bit 2. Hardwired to VIH or VIL to set the chip select address. Internally recognized as VIL if floating; 10 kΩ or less pull to a known state is recommended.
4	GND	power_in	Ground reference for the device.
5	SDA	bidirectional	Serial data line. Bi-directional open-drain I/O for the two-wire (I2C) bus; requires an external pull-up resistor and may be wire-OR'd with other open-drain devices. Data may change only while SCL is low.
6	SCL	input	Serial clock input. Rising edge latches data into the EEPROM, falling edge clocks data out. Compatible with 1 MHz (2.5-5V) or 400 kHz (1.8V) operation.
7	WP	input	Hardware write protect. When tied to VIH/VCC, all programming (write) operations are disabled; tie to VIL or leave floating to enable writes. Read operations are unaffected. If unconnected it is internally recognized as VIL; a 10 kΩ or less pull to a known state is recommended.
8	VCC	power_in	Positive supply input. Operating range 1.8 V to 5.5 V. Bypass with a local decoupling capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24c02bn.step`	122 KB	You want the bare part, or you mark your own boards.
`24c02bn-etched.step`	1.7 MB	You want the part with `24C02BN` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 425 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.
