PMS150C-S08 from PADAUK Tech, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Positive power supply input. Operating range 2.0 V to 5.5 V (subject to LVR tolerance).
2	PA7/CIN3-	bidirectional	Bit 7 of Port A: digital I/O with software-configurable pull-up resistor (Schmitt trigger input, CMOS-level two-state output). Also the CIN3- minus input source 3 of the general-purpose comparator (analog). Supports wake-up from sleep when padier bit 7 = 1.
3	PA6/CIN2-	bidirectional	Bit 6 of Port A: digital I/O with software-configurable pull-up (Schmitt trigger / CMOS two-state). Also the CIN2- minus input source 2 of the general-purpose comparator. Supports wake-up from sleep when padier bit 6 = 1.
4	PA5/PRST#	bidirectional	Bit 5 of Port A: input or open-drain output with pull-up resistor (Schmitt trigger / CMOS). Also serves as the hardware reset input PRST# (active low). Supports wake-up from sleep when padier bit 5 = 1.
5	PA3/CIN1-/TM2PWM	bidirectional	Bit 3 of Port A: digital I/O with software-configurable pull-up (Schmitt trigger / CMOS two-state). Alternate functions: CIN1- minus input source 1 of the comparator, and TM2PWM output of the 8-bit Timer2. Supports wake-up from sleep when padier bit 3 = 1.
6	PA4/CIN+/CIN4-/TM2PWM	bidirectional	Bit 4 of Port A: digital I/O with software-configurable pull-up (Schmitt trigger / CMOS two-state). Alternate functions: CIN+ plus input to comparator, CIN4- minus input source 4 to comparator, and TM2PWM output of the 8-bit Timer2. Supports wake-up from sleep when padier bit 4 = 1.
7	PA0/INT0/CO	bidirectional	Bit 0 of Port A: input or output with pull-up resistor (Schmitt trigger / CMOS two-state). Alternate functions: INT0 external interrupt line 0 (both rising and falling edges accepted), and CO comparator output. Supports wake-up from sleep when padier bit 0 = 1.
8	GND	power_in	Ground reference (0 V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`pms150c-s08.step`	122 KB	You want the bare part, or you mark your own boards.
`pms150c-s08-etched.step`	2.6 MB	You want the part with `PMS150C-S08` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 615 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
