AT24C16D-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 the bus is idle or pulled high with an external pull-up resistor. |
| 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 exceeding 10 kΩ and may be wire-ORed with other open-drain or open-collector bus pins. |
| 4 | VCC | power_in | Device power supply pin (1.7V to 3.6V operating range); operation at invalid VCC voltages may produce spurious results and should not be attempted. |
| 5 | WP | input | Write-protect input: connecting to GND allows normal write operations, connecting to VCC inhibits all memory writes, and when undriven it is internally pulled down to GND (disengaging above ~0.5 x VCC), so a known state is recommended. |
