STM8S903K3U3 Frequently Asked Questions (FAQs)

  • The maximum clock frequency that can be used with the internal oscillator is 16 MHz, but it's recommended to use a maximum of 12 MHz to ensure stability and accuracy.
  • To configure the WDT to reset the microcontroller, you need to set the WDT prescaler to a non-zero value, enable the WDT, and then write a value to the WDT counter register. The WDT will then reset the microcontroller if the counter reaches zero before being reloaded.
  • No, the UART on the STM8S903K3U3 only supports asynchronous mode. It does not have a clock output or input, and therefore cannot be used in synchronous mode.
  • To enable the internal pull-up resistors on the GPIO pins, you need to set the corresponding bit in the GPIOx_PUDDR register to 1. This will enable the internal pull-up resistor on the specified pin.
  • The minimum voltage required to program the microcontroller using the SWIM interface is 2.7V. However, it's recommended to use a voltage of at least 3.3V to ensure reliable programming.
