LP2951-Q1: I have a question regarding M3 suffix.

Part Number: LP2951-Q1

Tool/software:

This device is available with M3 and without M3, but the difference in front-end processes is not known.

Are the legacy chips not made in RFAB?

    Hi Sako- San,

    It is mentioned in section 8.1.2 that the legacy devices were made in Sherman and the new device is made in RFAB. RFAB is the newer facility that doesn't have the older process capabilities to make legacy devices.

    Regards

    Ishaan-san,


    Thank you for your prompt response.

    I would like to ask an additional question.
    So this device will be shipped with both legacy process SHE products and new process RFAB products, but if I specify M3, I will only get the shrunk RFAB products?
    I would like to know, are legacy design products ever produced in RFAB? (Because the electrical characteristics seem to have changed.)
    Also, the PKG grade has gone up, but if I want MSL1, do I have to choose M3 products?

    Best regards,
    T.Sako

    "So this device will be shipped with both legacy process SHE products and new process RFAB products, but if I specify M3, I will only get the shrunk RFAB products?"

    - Correct

    "I would like to know, are legacy design products ever produced in RFAB? (Because the electrical characteristics seem to have changed.)
    Also, the PKG grade has gone up, but if I want MSL1, do I have to choose M3 products?"

    - It depends on how legacy products are defined because for some parts, this is with respect to age and for some devices it is with respect to process. RFAB can only accommodate newer, 300mm processes. For MSL 1, you have to choose the newer (M3) devices.
