STM8L151K3U3 Frequently Asked Questions (FAQ)

  • 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.

  • To configure the WDT, you need to set the WDP bits in the WDT control register (WDT_CR) to select the timeout period, and then enable the WDT by setting the WDTE bit. Make sure to follow the correct sequence to avoid accidental resets.

  • Yes, the UART in the STM8L151K3U3 can be used in asynchronous mode with a baud rate generator. You need to configure the UART clock, set the baud rate, and enable the UART transmitter and receiver.

  • The STM8L151K3U3 has several low-power modes, including Halt, Active-Halt, and Low-Power Run. To implement a low-power mode, you need to configure the clock, disable unnecessary peripherals, and use the HALT or LPWRUN instructions. Refer to the datasheet and application notes for more information.

  • Yes, the internal flash memory of the STM8L151K3U3 can be used to store data, but it has a limited number of write/erase cycles. You need to use the flash programming interface and follow the guidelines for data storage in the flash memory.
