11AA160-I from Microchip Tech, in a TO-92-3. 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 | VSS | power_in | Ground reference pin for the device. |
| 2 | SCIO | bidirectional | Serial clock and data input/output pin for the single-wire UNI/O bus, carrying commands, addresses and data into and out of the device with the clock embedded via Manchester encoding. |
| 3 | VCC | power_in | Supply voltage; for the 11AA160 the device operates over 1.8V to 5.5V. |
