GN24C02A from GN Semic, 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	E0	input	Device address input bit 0. Tied to VCC or GND to form part of the slave address, allowing up to 8 GN24C02A devices on the same I2C bus. Should not be left floating.
2	E1	input	Device address input bit 1. Tied to VCC or GND to select one of eight slave addresses. Should not be left floating.
3	E2	input	Device address input bit 2. Tied to VCC or GND to select one of eight slave addresses. Should not be left floating.
4	GND	power_in	Device ground / 0 V reference.
5	SDA	bidirectional	I2C serial data line. Open-drain bidirectional; requires an external pull-up resistor to VCC (typ. 1.3 kΩ at 2.5-5.5 V, 10 kΩ at 1.7 V). Used to shift data in and out synchronous with SCL.
6	SCL	input	I2C serial clock input. Supports up to 400 kHz for VCC 1.7-2.5 V and up to 1 MHz for VCC 2.5-5.5 V. Data on SDA is latched on rising edges and may change on falling edges.
7	WCB	input	Write-control (write-protect) input. Tie to VCC to disable all write operations (read-only); tie to GND to enable normal read/write. Must not be left floating.
8	VCC	power_in	Supply voltage input. Operating range 1.7 V to 5.5 V; absolute max 6.25 V. Standby current 1-3 uA typical; active write current up to 1.6 mA at 5.5 V / 400 kHz.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gn24c02a.step`	122 KB	You want the bare part, or you mark your own boards.
`gn24c02a-etched.step`	1.8 MB	You want the part with `GN24C02A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 443 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.
