24C04-HXY 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	NC	unconnected	No connect. Leave floating or tie to GND. Not internally bonded.
2	A1	input	Device address input bit A1. Hardwired to VIH or VIL to set the chip select bits (bits 5-6) of the I2C device address 1010_A2A1_P0_RW. Internally recognized as VIL if left unconnected, but the datasheet recommends tying to a known level via a resistor <=10 kOhm.
3	A2	input	Device address input bit A2. Hardwired to VIH or VIL to set the chip select bits of the I2C device address. Internally recognized as VIL if left unconnected; recommend a hard tie via <=10 kOhm resistor.
4	GND	power_in	Device ground reference. Tie to system ground.
5	SDA	bidirectional	Serial data line, bi-directional. Open-drain output; requires an external pull-up (typically to VCC). Can be wired-OR with other open-drain devices on the I2C bus.
6	SCL	input	Serial clock input. Data is latched on the rising edge and clocked out on the falling edge. Rated up to 1 MHz at 2.5-5.5 V VCC and 400 kHz at 1.8 V VCC.
7	WP	input	Write protect input. When tied to VIH/VCC, all programming (write) operations to the EEPROM array are disabled; when tied to VIL or left unconnected, writes are allowed. Reads are unaffected. Recommend a hard tie via <=10 kOhm resistor rather than floating.
8	VCC	power_in	Supply voltage input. Operating range 1.8 V to 5.5 V (industrial temp -40 C to +85 C). Standby current < 1 uA. Absolute maximum 8 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24c04-hxy.step`	122 KB	You want the bare part, or you mark your own boards.
`24c04-hxy-etched.step`	1.6 MB	You want the part with `24C04-HXY` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 420 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.
