Hello Dongmei,

Good question. I will look into this and get back to you.

Did you purchase these from the same vendor? May I ask where you got them from?

Thank you and best regards,

Seong

Hi Dongmei,

Thank you for the top side images of the devices. Can you also send me images of the label that was on the box or packaging?

I would also like to see the lot codes/control values.

Thank you and best regards,

Seong

Hello Dongmei,

I've actually confirmed with my internal team that this is normal. The smaller die comes from a different TI fab.

Thank you and best regards,

Seong
