Hi,
Working on a wireless capacitance sensor based on the CY8C4248LQI-BL583. All components are rated to 85 degC or more.
The sensor works fine in room temperature but raising the temp makes it fail as early as 51 degC.
Failure temperature depends on which software I run on the sensor board. With the simple "Find Me" example failure occurs at around 70 degC.
I have tried heating various components e.g. oscillators and capacitors. But most indications points towards that it is the MCU that fails.
I understand the the information provided is not enough to pinpoint the root cause of the problem. I'm rather asking for troubleshooting advice.
