I am looking for components which works at high temperature. Especially I am looking for microcontrollers which works at 180 °C to 200 °C. I need to found microcontroller which works fine at extreme conditions. If the microcontroller have built in CAN interface then it would be really nice? or any other methods and microcontrollers that i can use for my project. The purpose microcontrollers is to get information from different sensors and perform some calibration.
I found one microcontroller from TEXAS which is SM320F28335-HT but the cost of that microcontroller is very expensive. Is there any microcontroller with low cost and works at high temperature.
