ATMEGA809-AFR Frequently Asked Questions (FAQs)

  • The ATMEGA809-AFR 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 in the ATMEGA809-AFR can be configured using the BODLEVEL fuse bits in the FUSEBYTE register. The BOD can be set to detect voltage levels of 1.8V, 2.2V, 2.7V, or 4.3V. The BOD can also be disabled by setting the BODLEVEL fuse bits to 0x00.
  • The maximum current that can be sourced or sunk by the I/O pins of the ATMEGA809-AFR 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 and to prevent overheating.
  • The internal oscillator of the ATMEGA809-AFR can be enabled by setting the CKSEL fuse bits in the FUSEBYTE register. The internal oscillator can be calibrated using the OSCCAL register. The internal oscillator frequency can be set to 1 MHz, 2 MHz, 4 MHz, or 8 MHz.
  • The power consumption of the ATMEGA809-AFR in sleep mode depends on the sleep mode used. In power-down mode, the current consumption is typically around 0.1 μA. In power-save mode, the current consumption is typically around 1 μA. In standby mode, the current consumption is typically around 10 μA.
