L3GD20H part marking or part markings in general

[PSwee.1]

I have a part that I believe to be a MEMS sensor. Unfortunately it has no company logo just some code numbers. The fact that it is a LGA-14 in 3*3mm makes me think it is a L3GD20H. No other manufacturer seems to have a MEMS part in that size. The L3GD20H datasheet makes no mention of markings for the chip (shame on you ST!). Can anyone confirm that "162 <new line> 3496 <new line> A46" is an L3GD20H. Or better yet point to a document that lists ST's chip markings. I am unable to find such a document.

Never mind. After going back through all my Digikey orders I found this part is actually an Invensense partl. ST should still add marking information on their datasheets.

Hi @PSwee.1​ , thank you for the note. For your (hopefully future) interest, the L3GD20H marking has the following meaning:

*zYZZ --> "Y" is the (assembly/production) lot year (e.g. "7" for 2017), "ZZ" is the year week (e.g. 41 is wk41)

3GDH --> is the part number code, "3GDH" = L3GD20H

abcde --> is a 5 digit code for the part traceability (including info on the chip ID)

Regards
