XC101S051 from Si Change, in a SOT-23-6. 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 | VA | power_in | Power supply input (3.3 V to 5.25 V single supply) that also serves as the ADC reference voltage, and VA must be set greater than or equal to the maximum VIN input to avoid maximum-code saturation. |
| 2 | GND | power_in | Analog input signal ground; all analog and digital signals are referenced to this pin. |
| 3 | VIN | power_in | Analog signal input with a range of 0 V to VA. |
| 4 | SCLK | input | Serial clock input that directly controls the conversion and readout process; the device starts a conversion on the third falling edge and completes it on the 14th falling edge. |
| 5 | SDATA | output | Serial data output that delivers MSB-first conversion data after three leading zeros and enters tri-state at the 14th falling SCLK edge, ending the conversion cycle. |
| 6 | CS | input | Active-low chip select: a falling edge wakes the device and starts a conversion, and pulling CS high before 10 SCLK cycles aborts the conversion and forces power-down with no valid data on the next conversion. |
