STM1818RWX7F Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the STM1818RWX7F is 1.8V to 3.6V.

  • The STM1818RWX7F has a built-in POR and BOR circuitry. The POR is triggered when the voltage supply drops below 1.4V, and the BOR is triggered when the voltage supply drops below 1.7V. You can use external resistors and capacitors to adjust the reset threshold and delay.

  • The STM1818RWX7F supports a maximum clock frequency of 32 MHz.

  • The WDT is used to reset the microcontroller in case of a software fault. You can enable the WDT by setting the WDTE bit in the WDTCSR register. The WDT timeout period can be set using the WDP bits in the WDTCSR register.

  • The internal oscillator is a 16 MHz RC oscillator that can be used as a clock source for the microcontroller. It can be enabled by setting the CKSEL bits in the CLKPR register.
