Part Number: DM3725

Hi Team,

We are using  DM3725CUS100 in one of our production projects. In our recent production, we got one issue with I2C and we found that there is some difference between the TOP Marking in recent and previous productions. We would like to know the difference between those highlighted Marking in the below attached images. 

1. DM3725CUS100-Top Marking in Old production

2.DM3725CUS100-Top Marking in recent production

Thanks & Regards,

E.Rohini

    Hi,

    These markings are explained in section 1.2 of the DM37x Errata: www.ti.com/.../sprz319f.pdf

    Hi Biser,
    There it is mentioned as
    1. YM denotes year/month.
    2. LLLL denotes Lot Trace Code.
    3. S denotes Assembly Site Code.
    So, it looks like there is no silicon variation between the two top marking parts.
    Or if there is any silicon updates also (only regarding to that highlighted top marking), please let us know

    Regards,
    E.Rohini

    There is no silicon revision differences between both devices. As it is described in Table 1 Silicon revision is identified by a code marked on the package. The code is of the format DM3730xCBP, where "x" denotes the silicon revision. In your case "x" is blank which means Rev 1.2.
    There is other silicon updates.
    The only difference which I found is temperature grade. For the first device DM3725CUSD100 range is -40 to 90 C but the second one DM3725CUS100 range is 0 to 90 C. If you are using the second one in temperature conditions below 0 C some issues could be appear.
