Hello

Using the ADUC832BSZ62-5

ESS Test were performed

Procedure:

System is ON.

Cooling up to -54 deg and then switching OFF.

Switch back to ON after some
time.

 

Problem:

Program fails at startup during boot sequence : Check sum error/

Preforming program FLASH memory damp revealed that one byte of the program flash memory was corrupted.

Note:

Reprogramming the flash brings back the good value to this byte. System is again well operating

 

Question:

Is this behavior normal when operated at such temperature? 

What is the probability of such events to occurs under such conditions.

From about 100 cards tested, this happened in one of the cards

Thanks

Freddy
