•For ARM-series chips during debugging and programming: Connect the SWD interface of the programmer to the SWD interface of the chip. Wiring: VREF (3.3V/VDD) – VDD GND – GND SWDIO – SWDIO SWCLK – SWCLK •For STM8-series chips: Connect the SWIM interface of the programmer to the SWIM interface of the chip. Note: Debugging STM8-series chips is not supported. Wiring: VREF (3.3V/VDD) – VDD GND – GND SWIM – SWIM RST – RST •For chips programmed via UART (e.g., N32S032): Connect the UART pins. Wiring: VREF (3.3V/VDD) – VDD GND – GND RX – TX TX – RX The PowerWriter client software provides wiring diagrams for all supported chip models and packages. Click 【Wiring Diagram】 to view. Below is an example for a specific chip:

2.5 JTAG connection type(Debugger)​

Connect the JTAG port on the switch board.

2.6 SPI connection type(Nor flash)​

Connect the SPI interface of the switch board.

2.7 Machine connection mode​

See Interface 8.

3.PWLINK2/PWLINK2 Lite​

The physical interface diagram of the PWLINK2/PWLINK2 Lite devices is shown below:

image-20250910165852516

Please note that the PWLINK2/PWLINK2 Lite do not support offline programming features and lack the pins required for standalone operation compared to the PW200/PW300. The definitions of the other pins remain the same. For specific wiring connections, refer to the PW200/PW300 section.

4.PW400​

The physical silkscreen diagram of the PW400 device is shown below:

Description of VDD, Vext, VREF,5V on the device
  • VDD,VEXT, and VREF are powered on at 3.3V by default. You can use the PowerWriter® client to change the power.See How to Set the interface Level .
  • The 5V pin can only stabilize the output 5V working voltage and is not controlled by software.
  • The VIN pin serves as a power input pin and is not designed to output voltage to external circuits.It is typically used to power the programmer through this pin when it is inconvenient to use a USB cable for power supply.
  • If you need information about the other pin functions, please consult the "Hardware Operating Status Description" section.
