I have encountered an issue with the W5500 ethernet IC. During our environmental testing, we subjected our product to a temperature of -40°C for 4 hours. Afterward, we noticed that the W5500 is not functioning. The microcontroller that is operating W5500 show there is no W5500 IC.
W5500 IC stop working totally.
I have two questions regarding this situation:
- What could be the reason behind this problem occurring?
- Could you please provide guidance on how to resolve this issue?
