24FC01T-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 | The SCL input is used to synchronize the data transfer to and from the device (I2C serial clock, 1 MHz compatible for the 24FC01). |
| 2 | VSS | power_in | Ground reference for the device; the WP pin must be tied to either VSS or VCC. |
| 3 | SDA | bidirectional | Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz), and may change only while SCL is low except for Start/Stop conditions. |
| 4 | VCC | power_in | Power supply; the 24FC01 operates from 1.7V to 5.5V over the Industrial (-40°C to +85°C) and Extended (-40°C to +125°C) temperature ranges. |
| 5 | WP | input | Write-protect input: tied to VSS enables normal read/write of the entire memory (00-7F), while tied to VCC inhibits all write operations without affecting reads. |
