Issues with ATmega4809 Microcontroller – Not Powering On

Hello, everyone!

I am experiencing issues with my ATmega4809 microcontroller. The device suddenly stopped powering on, and I can't seem to identify the cause. I've checked the power supply and connections, and everything appears to be in order.

Here are the details:

• Device: ATmega4809 Microcontroller
• Problem: Not powering on

I’ve reviewed the datasheet and features for the ATmega4809, which you can find here. However, I couldn’t pinpoint any specific issue related to my problem.

Has anyone else experienced similar issues with this microcontroller, or can anyone suggest potential troubleshooting steps? Any help would be greatly appreciated!

Thanks in advance!
