AM3352: Difference between AM3352BZCZA60 and AM3352BZCZ60

Kanae
Guru 10165 points
Part Number: AM3352


Tool/software:

Hi Support Team,

When changing from AM3352BZCZA60 to AM3352BZCZ60, the difference between each device is recognized
as the difference between -40 to 105°C products and 0-90°C products.
I need to report to a customer who is considering changing to the above devices,
so please provide me with detailed information on the design, performance, manufacturing process, etc.
as to the differences between the 105°C and 90°C products.

Best Regards,
Kanae

    Hello Kanae

    Please refer the inputs from the experts. I may not have additional inputs to share.

    I don’t there is a need to go into detail as the devices are identical except for temp grade.  The temp grade must be selected based on maximum expected TJ

     Blank is 0C to 95C TJ

    A is -40C to 105C TJ

     There is no difference in manufacturing process, and no other device differences to address/detail.

     If they were looking at a grade T part, then there is a restriction on DDR3 frequency.

     Regards,

    Sreenivasa

    Hi Sreenivasa,

    The customer's quality assurance representative asked the following additional question.

    You replied regarding AM3352BZCZA60 and AM3352BZCZ60,
    "There is no difference in manufacturing process, and no other device differences to address/detail."

    If they are all the same, how are the temperature grades different?
    I would like to know the reason and evidence for the different temperature grade.

    Could you please explain to the extent you are able to disclose any differences in the process of sorting,
    such as differences in design or testing processes on the above questions?

    Best Regards,
    Kanae

    I have shared what i received from the experts for the below.

    If possible, please share the customer use case and background for the query so that i can go back to the experts.

    The data sheet provides the temperature range for each of the selected number

    Figure 8-1. AM335x Device Nomenclature

    Hi Sreenivasa,

    Thank you for your support.

    This application is a measurement unit, and the product has been selected for
    a different temperature range to reduce the cost of a product already in mass production.
    I will again confirm the background of the query with the customer and the specific use case
    and get back to you.

    Hello Kanae,

    Thank you and the information would help to check internally if we have additional information to share.

    Hi Sreenivasa,

    Here is the customer's reply.

    I understand that there is no difference other than the temperature grade,
    but when I replace the 90°C product I would like to make a judgment
    as to whether it is acceptable to replace it as is without evaluation.

    The purpose is to confirm the information on the differences between the devices
    as a basis for decision making for replacement.

    Best Regards,
    Kanae

    Hello Kanae,

    Thank you.

    let me check with the team if we have additional input and likely we may not have any additional information.

    the data sheet is the reference and the Figure 8-1. AM335x Device Nomenclature mentions the supported temperature range.

    Hi Sreenivasa,

    Thank you for your support.

    Regarding AM3352BZCZA60 and AM3352BZCZ60,
    I understand that there is no difference in the manufacturing process and no other device differences
    in terms of addresses/details, as well as the temperature grades listed in the data sheet.

    Do you mean to say that the design and manufacturing processes are all the same,
    but there is screening to determine each temperature grade, but the specific details are not disclosed?
    Please confirm with your expert again.

    Hi Sreenivasa,

    Thank you for your reply.

    Is it correct that “OPN” means “Ordering Part Number”?
    In that case, is my understanding correct that my view is correct
    as long as the model numbers up to “AM3352BZCZ” are the same?

    Best Regards,

    Sorry i need you to elaborate.

    The E2E focus is 

    TEMPERATURE RANGE

    The explanation above is valid when all other values in the OPN is same except the temperature range.

    Hi Sreenivasa,

    Thank you for your prompt reply.
    This question is a comparison of the following devices.
    AM3352BZCZA60 , AM3352BZCZ60

    The difference is that the letter of the temperature range is A or blank,
    so I think it is valid, if all other values of OPN are the same except the temperature range.
