24C02A from lingxingic 24C02A LX, 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. A2/A1/A0 form the hardware-programmable slave address (up to 8 devices on one I2C bus).
2	A1	input	Device address input bit 1. Tied high or low to set part of the 7-bit I2C slave address.
3	A2	input	Device address input bit 2. Tied high or low to set part of the 7-bit I2C slave address.
4	GND	power_in	Ground reference (0 V).
5	SDA	bidirectional	I2C serial data. Open-drain bidirectional line; requires an external pull-up resistor (typ. 4.7 kΩ, depending on bus capacitance and speed). Can be wire-OR'd with other open-drain devices.
6	SCL	input	I2C serial clock input. Data latched into the EEPROM on the rising edge; data driven out on the falling edge. Supports up to 400 kHz at VCC=1.8-2.5 V and 1 MHz at VCC=2.5-5.5 V.
7	WP	input	Write protect. Tie to GND for normal read/write access; tie to VCC to write-protect the entire 2K array. Read access is always allowed.
8	VCC	power_in	Positive supply, 1.8 V to 5.5 V (absolute max 6.25 V). Typical ICCR=0.2 mA at 400 kHz read, ICCW=0.8 mA at 400 kHz write; standby ISB2 ≤ 3 µA at VCC=5.5 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24c02a.step`	122 KB	You want the bare part, or you mark your own boards.
`24c02a-etched.step`	1.5 MB	You want the part with `24C02A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 373 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.
