Preface
The ATmega4809 Xplained Pro evaluation kit is a hardware platform to evaluate the ATmega4809
microcontroller.
Supported by the integrated development platform Atmel Studio, the kit provides easy access to the
features of the ATmega4809 and explains how to integrate the device into a custom design.
The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger and no external
tools are necessary to program or debug the ATmega4809.
The Xplained Pro extension kits offer additional peripherals to extend the features of the board and ease
the development of custom designs.

Page 26: Hardware Revision History
Revision 4 has a new PCB that fixes the SPI MISO/MOSI issue in revision 3. Instead of the crystal documented in Crystals, the 32.768 kHz crystal on ATmega4809 Xplained Pro revision 4 is a Kyocera Corporation ST3215SB32768E0HPWBB 9 pF crystal. This crystal configuration is not optimally matches and has a capacitance mismatch that causes the oscillation frequency to be off by ~30 ppm. -
