Original question:

TPS65219: programable PMIC part number

TPS65219: Programming the TPS65220 for DDR4 RAM

Part Number: TPS65219
Other Parts Discussed in Thread: TPS65220, AM6442, ,

Hello! 

My project requires me to use DDR4 Memory with the AM64x processor. I am interested in using the TPS65220 as it is "Functional Safety Capable" but when looking through the TPS65220 datasheet & application note it only mentions "External Memory Support for LPDDR4". Since this is a PMIC, is it possible for us to use the TPS65220 to work with the AM6442 & DDR4 memory by doing a custom NVM for this device? (or if another configuration is available). I have yet to see any documentation regarding the hardware kit to be able to program the PMIC as well or variants of TPS65220 to support DDR4. 

PMIC Variants

Thanks,

    Hi,

    Thanks for reaching out! The TPS65220 PMIC can power AM64x with any memory type (like LPDDR4 or DDR4). The TPS6522053 is pre-programmed to support the LPDDR4 voltage (1.1V). Since the TPS65219 and TPS65220 are flexible power management devices, they can also be programmed to power other memory type or processors with equivalent power requirements.

    Here are the options available:

    • For high volume opportunities: TI creates a new TPS65220xx orderable part number with unique NVM settings. Please reachout to your local sales/FAE representative to verify if this opportunity meet the volume requirements.   
    • For low volume opportunities: choose one of the pre-configured TPS65219 devices to power AM64x+DDR4 or use TPS6521905-Q1 (automotive, user-programmable). For the user-programmable version, TI helps create the PMIC NVM configuration file and customers are responsible to program the PMIC in their production line or through third party programming services.   

    Let us know if there are any questions.

    Thanks,

    Brenda

    Thank you for the information, the TPS6521905-Q1 would suit my requirements. 

    Best Regards,

    Awesome! Let us if you have any questions or need additional technical support. We can help create the NVM config file that can be loaded into the PMIC GUI to easily re-program the device. 

    Thanks,

    Brenda
