STM8S105K6U3ATR Frequently Asked Questions (FAQ)

  • 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 to a non-zero value and enable the WDT reset. This can be done by writing to the WDT control register (WDT_CR) and setting the WDTS bit.

  • 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 synchronous mode or an external UART chip.

  • To enable the BOR feature, you need to set the BOREN bit in the Power Management Control Register (PMC_CR). You also need to configure the voltage threshold by writing to the BORVTH register.

  • The minimum voltage required for the STM8S105K6U3ATR to operate correctly is 2.95V. However, it's recommended to use a voltage of at least 3.0V to ensure reliable operation.
