ATMEGA4808-AU Frequently Asked Questions (FAQs)

  • The ATMEGA4808-AU 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 specified parameters.
  • The BOD in the ATMEGA4808-AU 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 BODLEVEL fuse bits to 0x00.
  • The I/O pins of the ATMEGA4808-AU can source or sink a maximum current of 20mA per pin. However, the total current sourced or sunk by all I/O pins should not exceed 200mA to ensure that the device operates within its specified parameters.
  • The internal oscillator of the ATMEGA4808-AU 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 in the FUSEBYTE register. The internal oscillator can be calibrated using the OSCCAL register.
  • The power consumption of the ATMEGA4808-AU varies depending on the operating mode. In active mode, the power consumption is typically around 10mA at 5V and 20MHz. In power-down mode, the power consumption is typically around 0.1mA at 5V. In power-save mode, the power consumption is typically around 1mA at 5V.
