Good day
The working equipment has been exposed to water.
After that, the chip began to get very hot.
After cleaning and removing water, it still continues to warm up.
The supply department brought the chip, but all the numbers and letters on the 2nd and 3rd lines are different
You can tell where you can find all the information about all letters in the 2nd and 3rd lines.
thanks in advance
Hello,
The 2nd line (0L80M) represents maskset.
The 3rd line (QQEP0427, QQJJ0502) represents trace code, the meaning is confidential.
Since the part numbers and masksets are the same on both MCUs you can use the second one as a replacement.
I hope it helps.
Best regards,
Diana
Good Day
thanks for the info
