ATMEGA808-XU Frequently Asked Questions (FAQs)

  • The ATMEGA808-XU can operate at a maximum clock frequency of 20 MHz, but it is recommended to use a clock frequency of 16 MHz or lower for optimal performance and to ensure that the device operates within its specifications.
  • The BOD can be configured using the BODLEVEL fuse bits in the FUSEBYTE register. The BOD can be set to detect voltage levels between 1.8V and 4.3V in 0.1V increments. The BOD can also be disabled by setting the BODDISABLE fuse bit.
  • The RESET pin is an active-low input that can be used to reset the device. When the RESET pin is pulled low, the device will reset and all registers will be initialized to their default values. The RESET pin can also be used to wake the device from sleep mode.
  • The internal oscillator on the ATMEGA808-XU can be enabled by setting the CKSEL fuse bits in the FUSEBYTE register. The internal oscillator frequency can be selected using the SUT_CKSEL fuse bits. The internal oscillator can be calibrated using the OSCCAL register.
  • The maximum current that can be sourced or sunk by the I/O pins on the ATMEGA808-XU is 40 mA. However, it is recommended to limit the current to 20 mA or less to ensure that the device operates within its specifications.
