24LC64FT-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 that synchronizes 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 needs a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz). |
| 4 | VCC | power_in | Power supply, +1.7V to 5.5V per the pin table (2.5V to 5.5V for the 24LC64F per the device selection table). |
| 5 | WP | input | Write-Protect input that must be tied to VSS or VCC; at VSS writes are enabled, at VCC writes are inhibited for the upper 1/4 of the array (1800h-1FFFh). |
