PFC161-U06 from PADAUK Tech, 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 | PA4 | bidirectional | General-purpose I/O with selectable pull-up/pull-down and wakeup; also comparator CIN+/CIN-, TM3PWM output and touch key TK6, with Strong/Normal drive selectable by code option. |
| 2 | GND/AGND | power_in | Ground pin for the IC and analog ground, bonded together internally (double bonding) and the same external pin. |
| 3 | PA5 | bidirectional | General-purpose I/O with pull-up/pull-down and wakeup; also external reset PRSTB, TM3PWM output, touch key TK9, INT0A external interrupt and programming pin (ICVPP, 5V in limited-voltage mode, 6V in normal mode), with a 33 ohm series resistor advised when used as input in high-EMI systems. |
| 4 | PA6/PA7 | bidirectional | PA6 and PA7 share this one pin on the SOT23-6 package (PA6 also crystal oscillator, touch key TK8 and ICPDA programming; PA7 also crystal oscillator, touch key TK10 and CS); never drive PA6 and PA7 to opposite levels at once or the pin is shorted. |
| 5 | VDD/AVDD | power_in | Positive supply for the IC and analog supply, bonded together internally and the same external pin; operating range 2.2V to 5.5V. |
| 6 | PA3 | bidirectional | General-purpose I/O with pull-up/pull-down and wakeup; also comparator CIN-, TM2PWM output, touch key TK5 and ICPCK programming pin, with Strong/Normal drive selectable by code option. |
