# WS8000P16ES8

**wisesun** · Microcontrollers (MCU/MPU/SOC) · SOP-8

WS8000P16ES8 from wisesun, in a SOP-8. 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 | GND | power_in | Ground pin of the SOP8 package (datasheet Table 2 lists it as GND with no further limits given). |
| 2 | PB3 | bidirectional | General-purpose digital I/O, which defaults to the JLINK TCK function. |
| 3 | PB5 | bidirectional | General-purpose digital I/O, which defaults to the JLINK TMS function. |
| 4 | PA3 | bidirectional | Analog and digital I/O pin usable as a GPIO. |
| 5 | XO16M | output | Output of the 16MHz/32MHz crystal oscillator. |
| 6 | XI16M | input | Input of the 16MHz/32MHz crystal oscillator. |
| 7 | VDD33 | power_in | Power supply input, 2.5V to 3.6V. |
| 8 | ANT | bidirectional | RF signal input/output (single-ended RF interface). |
