TPS65219: Question about program environment.

Kazuya Nakai59
Guru 21645 points
Part Number: TPS65219

Hello guys,

One of my customers is considering using TPS65219 for AM62xx.
At this moment, they have the following question.

Q. We want to program TPS65219 internal setting.
    Do you prepare any program tool or program environment for TPS65219?

Your reply would be much appreciated.

Best regards,
Kazuya.

    Hi,

    Thanks for posting this question on E2E. What input supply and DDR memory will the application use? We have some pre-configured TPS65219 devices that might meet the application requirements. 

    We also have the TPS6521905 which is the user-programmable version that can be used to configure a custom NVM using the TPS65219-GUI. I have attached the preliminary programming guide with the instructions. Please let us know if you need any technical support with the NVM programming and we will be happy to help.

    Hi Brenda,

    Thank you very much for your reply.

    I will ask the customer whether one of TPS6521901~04 is suitable to their request or not.
    And could I ask you an additional question?

    Q. Can our customer buy the socketed EVM in the document for programing TPS6521905 configuration by themselves? 
         If the answer is yes, could you tell me how to buy?

    Thank you again and best regards,
    Kazuya.

    Hi,

    In addition to the TPS6521901-04, we also have new variants that have not been released yet. If we get more information about the application use case like input supply and DDR memory, we might be able to identify a NVM config.

    The socketed EVM is expected to be released by the end of the month. In the meantime customers can order the TPS65219EVM (https://www.ti.com/tool/TPS65219EVM) and re-program the PMIC following the instructions in the programming guide. 

    Thanks,

    Brenda

    Hi Brenda,

    Thank you for the information.

    I understood that the socketed EVM will be released by the end of June.
    Also I got the following information from the customer.
    VIN of TPS65219 is 5V and DDR memory part number is Micron MT40A1G16KD-062E:E.

    Are you able to identify a NVM config?

    Thank you again and best regards,
    Kazuya.

    Hi,

    For 5V, DDR4 (1.2V) we have the following preconfigured NVMs:

    • TPS6521901: supports 5V Vin, DDR4 and VDD_CORE=0.75V. Here is the link to the TRM which shows the default register settings: TPS6521901 Technical Reference Manual (power block diagram on page# 10)

    • TPS6521907: supports 5V Vin, DDR4 and VDD_CORE=0.85V. Please find the preliminary TRM attached (power block diagram on page# 10).

    Thanks,

    Hi Brenda,

    Thank you very much for the information and I'm sorry to be late my response.

    The customer checked those documents but they said those device are not suitable to their power sequence requirement.
    Their requirement is the follow.
    1. Power on sequence
        VCC(5V, (VSYS, PIN_Bx, PVIN_LDOx) ---> BACK1(1.1V)/BACK2(1.8V) --1.5ms--> LDO3(2.5V)
        --1.5ms--> LDO2(1.2V) --3.0ms--> BACK3(3.3V)/LDO1(3.3V or 1.8V) --10ms--> nRSOUT(L->H).

    2. Power off sequence
        nRSOUT(H->L) --10ms--> BACK3(3.3V)/LDO1(3.3V or 1.8V) --1.5ms--> BACK1(1.1V)/BACK2(1.8V)/LDO3(2.5V)/LDO2(1.2V).

    Do you have any plan to release a version of TPS65219 version which has the power sequence above?
    If this answer is no. i think the customer need to program socketed EVM you will release by June/end/
    Is the EVM release timing not     changed? Still by June/end?

    Thank you again and best regards,
    Kazuya.

    Hi,

    If none of the pre-configured NVMs meet the power requirements, TI customers can use the TPS65219-GUI and the socketed EVM (expected to be available by end of June-2023) to define the PMIC NVM configuration. For production volume of a custom NVM, we have the following options: 

    • High volume: TI creates a custom part number with the NVM settings defined by the customer.  
    • Low volume: Customers implement the NVM programming on their production line or work with a distributor. 

    Thanks,

    Brenda

    Hi Brenda,

    Thank you very much for your reply.

    The number of the customer production is only 10kU/Y.
    Is this number low volume, isn't this?

    Thank you again and best regards,
    Kazuya.

    Hi Brenda,

    Could I ask you an additional question as the below?

    Q.
    What is the high volume threshold roughly?

    Thank you again and best regards,
    Kazuya.

    How was this sequence developed? It doesn't seem to meet the sequence requirements from the AM62 processor which are documented "Power Supply Sequencing" section of the datasheet. 

    For a custom NVM, unless it's a common re-usable use case, the threshold is $2M LNR.

    Hi Brenda,

    Thank you very much for your reply.

    The customer is going to use TPS65219 for Renesas processor.
    Could you please give me your answer to the following questions?

    Q1. What is the part number of TPS65219 family which customer can program using the socketed EVM?

    Q2.   When is RTM timing of Q1 answered TPS59219xx?

    Thank you again and best regards,
    Kazuya.

    Hi,

    The table below shows the orderable part numbers for the user-programmable version. The first two for non-automotive applications will be released by end of this month or beginning of July-2023. The last part number for automotive applications (higher temp) will be released in 3Q2023.

    Which Renesas processor is the application using? We have preliminary power mapping diagrams showing the TPS65219 PMIC powering Renesas. If could could provide the Renesas part number, we might be able to provide a pre-configured NVM file ready to be loaded into the PMIC NVM using the TPS65219-GUI.

    Thanks,

    Brenda

    Hi Brenda,

    Thank you very much for the information.

    I asked them what Renesas processor they are considering is.
    Their answer is RZ/G2L. Is this answer enough for you?

    Thank you again and best regards,
    Kazuya.

    Hi,

    Thanks for sharing! That should be enough information to identify the Renesas processor. We should be able to provide the NVM file by end of the week (06/23/2023).

    Thanks,

    Brenda

    Hi,

    Thanks again for your patience here as we work on the release for the TPS6521905 user-programmable PMIC. I have attached a draft PDF with the power mapping between the TPS65219 PMIC and the Renesas processor. I'm also attaching a CSV file with the PMIC NVM configuration that can be loaded with the TPS65219-GUI to re-program the device memory. Once this file is loaded on the GUI, changes can be made if needed. Let us know if there are any questions or need additional support to program the PMIC.

    Hi Brenda,

    Thank you very much for your strong support. Also I'm sorry to be late my response.

    Could I ask you an question about socketed EVM?
    I can't see the socket EVM on TI web site. Has the EVM been released?

    Thank you again and best regards,
    Kazuya.

    Hi,

    Yes! we have released the programming guide, GUI, socketed EVM as well as the user-programmable device (TPS6521905) for 5x5mm and 4x4mm package. Please note RHB is the 5x5 mm package and RSM is the 4x4 mm package. Below are the links to the resources. Please let us know if you have any questions or need additional technical support.  

    Thanks,
