AT24C04C-STUM-T 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 clocks data to and from the device; command and input data on SDA are latched on the rising edge of SCL and output data is clocked out on the falling edge, and SCL must be forced high when idle or pulled high with an external pull-up. |
| 2 | GND | power_in | Ground reference for the power supply, to be connected to system ground. |
| 3 | SDA | bidirectional | Open-drain bidirectional serial data pin that requires an external pull-up resistor (not to exceed 10 kΩ) and may be wire-ORed with other open-drain or open-collector devices on the bus. |
| 4 | VCC | power_in | Device power supply pin, operating from 1.7V to 5.5V; operation at invalid VCC voltages may produce spurious results. |
| 5 | WP | input | Write-protect input that allows normal writes when connected to GND and inhibits all writes to the full array when connected to VCC; it is internally pulled down to GND if left floating, but connecting it to a known state is recommended. |
