About Teensy 4.1 Operating Temperature

We have enabled the UDP and UART function.
Put Teensy 4.1 in the oven to 70°C. it will repeatedly restart.
So what temperature range can Teensy 4.1 work?



thanks.

Teensy uses the commercial temperature range chips. I think they are rated 0-55 C.
 
But the operating temperature range of the main core (MIMXRT1062 DVJ6B) is 0-95°C ,right?

I hope others reply, but that is the internal junction temperature, and from what I can see, that temperature can easily reach 30 C above ambient if running at 600 MHz. I think 0-55 ambient allows for keeping the junction temperature well below 95. You can also put a heatsync on it. The life of the chip goes down rapidly if you operate at a junction temperature of 95.
 
Teensy's startup code by default turns on temperature monitoring. If you use the tempmonGetTemp() function to get the current internal temperature, what values are you seeing?
 
That makes perfect sense, the temperature monitor panic alarm is set at 90 degrees to protect it from damage. You could disable it but it's not likely to survive operating at that temperature.

We are currently considering a cooling solution for the CPU.
It seems that it can run.
