Hi Andrea,

I will show you the mean of the KE series product number scheme, and the 2N22J stand for the mask number.

Then you can get to know what exactly chip you use after you have the information of product and mask number.

MKE02Z16VLC2	M02Q4VLC
MKE02Z16VLC4	M2Q4VLC4
MKE02Z32VLC2	M02Q5VLC
MKE02Z32VLC4	M2Q5VLC4
MKE02Z64VLC2	M02Q6VLC
MKE02Z64VLC4	M2Q6VLC4
MKE04Z8VFK4	M04Q3V
MKE04Z8VTG4	M04Q3VTG

Have a great day,

hi,I  have a confusion about the marking.Why the marking of two components from the same package have a different marking? The part number is  S9S12G64AMLF.

Please advise what is the date code for the top marking "XNAQ0Q" for the part number MKE02Z64VLC4? Thanks.

Top Marking:

1st line: M2Q6
2nd line: VLC4
3rd line: 2N22J
4th line: XNAQ0Q
