High-temperature microcontroller

[Trior]

Hello everyone,

I am looking for a microcontroller to replace a Teensy 4.0. The problem is that the Teensy doesn't cope well with high temperatures.

The specifications I'm looking for are as follows:

- High maximum operating temperature, at least 125 degrees Celsius

- Minimum 13-bit analog-to-digital converter (ADC)

- Capable of handling 1000Hz data sampling and high-frequency data shaping (~200Hz)

- Multiple analog inputs

- Serial communication

- Powered at 5V or less (preferably the minimum)

- I'd prefer to be able to download Arduino code onto it, or else in C

- Requires a simple assembly, not too many components
Many thanks to all

Look for Mil Spec (Military Specification) devices. These usually go to 125degC but expect to pay Mil Spec prices too!

Easiest way would to fit decent cooling.
