24FC16T-I from Microchip Tech, in a SOT-23-5. 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 | SCL | input | Serial Clock input used to synchronize data transfer to and from the device. |
| 2 | VSS | power_in | Ground. |
| 3 | SDA | bidirectional | Serial Address/Data I/O, an open-drain bidirectional pin that requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz). |
| 4 | VCC | power_in | Power supply; 1.7V-5.5V for 24FC16 (2.5V-5.5V for 24LC16B). |
| 5 | WP | input | Write-Protect input that must be tied to VSS (normal read/write of entire memory 000-7FF) or to VCC (write operations inhibited, reads unaffected). |
