STM8L151K3U6 datasheet by STMicroelectronics

STM8L151K3U6 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 16 MHz, but it depends on the voltage and temperature range. Refer to the datasheet for more information on the oscillator frequency ranges.
• How do I configure the watchdog timer (WDT) to reset the microcontroller?
  To configure the WDT to reset the microcontroller, you need to set the WDT prescaler and counter values, and enable the WDT reset. This can be done by writing to the WDT control registers (WDT_CR and WDT_SR). Refer to the STM8L15x datasheet and the STM8L15x programming manual for more information.
• Can I use the UART in asynchronous mode with a baud rate higher than 115200 bps?
  No, the UART in asynchronous mode is limited to a maximum baud rate of 115200 bps. If you need higher baud rates, you need to use synchronous mode or use an external UART with a higher baud rate capability.
• How do I enable the brown-out reset (BOR) feature?
  To enable the BOR feature, you need to set the BOREN bit in the Power Control Register (PWR_CR). You also need to configure the voltage threshold and hysteresis values using the BORV and BORH bits in the PWR_CR register.
• What is the minimum voltage required for the microcontroller to operate?
  The minimum voltage required for the STM8L151K3U6 to operate is 1.8V, but it depends on the frequency and temperature range. Refer to the datasheet for more information on the operating voltage ranges.
