CAT24C02WI-GT3-TUDI from Tudi, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Device address input hard-wired to set the chip's address on the 2-wire bus; an internal circuit biases it low if left floating. |
| 2 | A1 | input | Device address input hard-wired to set the chip's address on the 2-wire bus; an internal circuit biases it low if left floating. |
| 3 | A2 | input | Device address input hard-wired to set the chip's address on the 2-wire bus; an internal circuit biases it low if left floating. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that may be wire-ORed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input; data is clocked into the device on the positive edge and out on the negative edge of SCL. |
| 7 | WP | input | Write protect: connecting to GND allows normal read/write operation, while connecting to VCC write-protects the full (2K) array. |
| 8 | VCC | power_in | Power supply, 1.7 V to 5.5 V for operation at 400 kHz (2.5 V to 5.5 V for 1 MHz). |
