STM8S903K3T3C Frequently Asked Questions (FAQs)

  • The maximum clock frequency that can be used with the internal oscillator is 16 MHz. However, it's recommended to use a clock frequency of up to 12 MHz to ensure reliable operation.
  • To configure the WDT to reset the microcontroller, you need to set the WDT prescaler and counter values using the WDT_CR and WDT_CNTR registers. You also need to enable the WDT by setting the WDTE bit in the WDT_CR register.
  • No, the UART peripheral in asynchronous mode is limited to a maximum baud rate of 115200 bps. If you need a higher baud rate, you need to use the UART in synchronous mode or use an external UART chip.
  • To enable the BOR feature, you need to set the BOREN bit in the RCC_CSR register. You also need to configure the voltage threshold using the BORVOLT bits in the RCC_CSR register.
  • Yes, the internal flash memory can be used as a data storage area. However, you need to use the flash programming interface (FPI) to write data to the flash memory, and you need to ensure that the data is stored in a way that does not interfere with the program code.
