Question:
Old data code or new date code, if we do DIE test, if the ic chips are original, there is NS logo inside, right?
Thanks

Hello Hao,
Yes. There should be either a NS logo or National "flag" logo for the "MX" suffix devices. The die was not changed in the acquisition and should still contain the National die markings and grafiti.
