Can anyone suggest me microcontrollers works at extreme conditions.

[veerubiji]

Hi,

I am looking for components which works at high temperature. I am looking especially microcontroller which works at 170 degree centigrade to 200 degree centigrade (C). I am designing downhole electronics for oil and gas industry. 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.

Thanks in advance.
