Part Number: MSP430F5438A
Other Parts Discussed in Thread: MSP430G2553, , MSP430G2955

Hi,

Where can I get the Tjmax(junction temperature max) information of MSP430F5438A and MSP430G2553?

Customer is asking about this

Regards,

Ted

    Hi Ted,
    For F4338A, it's in section 5, Table 5.1.

    For the G part, I will need to submit a special request. Who is this for?
    We dont typically spec this for value line parts.

    LG Electronics factory requested this data. Could you share this data through e-mail?

    Ted,

    By "don't normally spec this", I meant it will have to be tested. I can share via e2e once that's done, though. :-)

    Which package for the 2553?

    Also is there a specific power level they want to spec for? 

    Or do they have specific power modes, voltage, and speeds?

    I'll submit the request once I have this data, but it will take us time to run the test.

    Package : MSP430G2553IPW28
    Voltage they are using : 3.3V
    Power Mode : Active mode
    Speed : 16MHz
    They just want to get typical Tjmax data as F5438A.

    Regards,
    Ted

    Hi Ted,
    I'm trying to track all these down for you, but we may not be able to spec all of those.

    For the G2553
    Theta JA is 72.2 and Theta JC (top) is 18.3

    Hello Cameron,

    One of my customer in AA also requesting Tj max value of MSP430G2955.
    Could you provide me and Ted about your test results if you've done, via email?

    For my customer's case, they want over 95C Tj max as F5xx/F6xx datasheets have.
    It is very important for me to deliver this within a week.

    With my cases, Customer uses MSP430G2955IRHA40 with 3.0V, 1MHz and only use active mode.

    Thanks.
