24CW160-I from Microchip Tech, in a SOIC-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 | NC | unconnected | No connect pin with no internal connection to the device. |
| 2 | NC | unconnected | No connect pin with no internal connection to the device. |
| 3 | NC | unconnected | No connect pin with no internal connection to the device. |
| 4 | VSS | power_in | Ground reference pin for the device. |
| 5 | SDA | bidirectional | Open-drain serial data pin that requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz and 2 kΩ for 400 kHz and 1 MHz), and changes only while SCL is low except for Start and Stop conditions. |
| 6 | SCL | input | Serial clock input used to synchronize data transfer to and from the device. |
| 7 | NC | unconnected | No connect pin with no internal connection to the device. |
| 8 | VCC | power_in | Device power supply pin; the device operates from 1.6V to 5.5V. |
