AT24C02 from HXY MOSFET, 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 least-significant bit of the I2C slave address. Recommended pull-up/pull-down 10 kΩ or less; internally treated as VIL if left floating.
2	A1	input	Device address input bit 1. Hardwired to VIH or VIL to set slave address bit. Recommended pull resistor 10 kΩ or less.
3	A2	input	Device address input bit 2 (MSB of the 3 chip-select bits). Hardwired to VIH or VIL. Recommended pull resistor 10 kΩ or less.
4	GND	power_in	Ground reference for the device.
5	SDA	bidirectional	Serial data line. Bi-directional open-drain I/O; requires an external pull-up resistor to VCC. Can be wire-ORed with other open-drain devices on the I2C bus.
6	SCL	input	Serial clock input. Rising edge latches data into the EEPROM; falling edge clocks data out. Schmitt-triggered, filtered input for noise immunity.
7	WP	input	Write protect. Tie to VIL/GND or leave unconnected to enable programming; tie to VIH/VCC to disable all write operations (read is unaffected). Recommended pull resistor 10 kΩ or less.
8	VCC	power_in	Supply voltage, 1.8 V to 5.5 V (industrial temperature range -40 °C to 85 °C).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at24c02.step`	122 KB	You want the bare part, or you mark your own boards.
`at24c02-etched.step`	1.6 MB	You want the part with `AT24C02` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 392 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.
