ATMEGA48A-AUR Frequently Asked Questions (FAQ)
-
The maximum clock frequency for ATMEGA48A-AUR is 20 MHz, but it can also be operated at lower frequencies down to 0 Hz for power-saving modes.
-
The BOD can be configured using the BODLEVEL fuse bits in the FUSE BYTE section of the device. The BOD can be set to detect voltage levels between 1.8V and 4.3V.
-
The maximum current that can be sourced by an I/O pin is 40 mA, and the maximum current that can be sunk is 60 mA. However, the total current sourced or sunk by all I/O pins should not exceed 200 mA.
-
The internal oscillator can be enabled by setting the CKSEL fuses to '11' and the SUT fuses to '10'. The oscillator frequency can be calibrated using the OSCCAL register.
-
The Reset Pin is an active-low input that can be used to reset the device. When the pin is low, the device is held in reset. The pin can also be used to wake the device from power-down modes.
