AT24C16C-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: command and input data on SDA are latched on its rising edge, output data on SDA is clocked out on its falling edge, and it 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, which should be connected to the system ground. |
| 3 | SDA | bidirectional | Open-drain bidirectional serial data pin that must be pulled high with an external pull-up resistor not exceeding 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; the device operates from 1.7 V to 5.5 V, and operation at invalid VCC voltages may produce spurious results and should not be attempted. |
| 5 | WP | input | Write-protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits writes to the full array; if left floating it is internally pulled down to GND, and Microchip recommends driving it to a known state. |
