24C64N from XBLW 24C64N XBLW, in a DIP-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/chip select address input bit 0. Hardwired to VIH or VIL to set the lower bit of the I2C slave address. Internally pulled to VIL if left unconnected.
2	A1	input	Device/chip select address input bit 1. Hardwired to VIH or VIL to set a bit of the I2C slave address. Internally recognized as VIL if left unconnected.
3	A2	input	Device/chip select address input bit 2. Hardwired to VIH or VIL to set the upper bit of the I2C slave address. Internally recognized as VIL if left unconnected.
4	GND	power_in	Ground reference for the device.
5	SDA	bidirectional	Serial data line for the two-wire (I2C) interface. Open-drain output; requires an external pull-up resistor to VCC and can be wire-OR'd with other open-drain devices.
6	SCL	input	Serial clock input. Rising edge latches data into the EEPROM; falling edge clocks data out. Supports 1000 kHz (2.5V-5.5V) and 400 kHz (1.8V) operation.
7	WP	input	Write Protect. When tied to VIH or VCC, all programming operations are disabled (read still works). When tied to VIL or left unconnected, writes are allowed.
8	VCC	power_in	Power supply input, 1.8V to 5.5V. Absolute maximum 8V; input voltage on any pin -0.3V to VCC+0.3V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`24c64n.step`	271 KB	You want the bare part, or you mark your own boards.
`24c64n-etched.step`	1.4 MB	You want the part with `24C64N` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 354 faces against 148 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.
