24C32BN from XBLW 24C32BN 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. Hardwire to VIH or VIL to set the I2C slave address; recommended pull resistor <=10 kOhm. Do not leave floating due to capacitive coupling.
2	A1	input	Device address input bit 1. Hardwire to VIH or VIL to set the I2C slave address; recommended pull resistor <=10 kOhm.
3	A2	input	Device address input bit 2. Hardwire to VIH or VIL to set the I2C slave address; recommended pull resistor <=10 kOhm.
4	GND	power_in	Device ground reference (0 V).
5	SDA	bidirectional	I2C serial data line. Open-drain bidirectional pin; requires an external pull-up resistor to VCC and can be wire-OR'd with other open-drain devices.
6	SCL	input	I2C serial clock input. Rising edge latches data into the EEPROM, falling edge clocks data out. Compatible with 1 MHz (2.5-5 V) and 400 kHz (1.8 V) operation.
7	WP	input	Write protect input. Tie to VIL (or leave open) to allow programming; tie to VIH/VCC to disable all write operations. Reads are unaffected. Recommended pull resistor <=10 kOhm.
8	VCC	power_in	Supply voltage input. Operating range 1.8 V to 5.5 V; absolute maximum 8 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24c32bn.step`	122 KB	You want the bare part, or you mark your own boards.
`24c32bn-etched.step`	1.7 MB	You want the part with `24C32BN` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 431 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.
