Part Number: TPS65988

  • how to update TPS65988 firmware by EC or PCH?
  • in Windows 10, does the TPS65988 supporting UCSI (USB Type-C Connector System Software Interface) or UcmCx(USB Connector Manager Class extension)?
  • Do we support the driver if goes in UcmCx mode? 
  • Hello Peter,

    For TPS65988 update by EC, please refer to the two application notes:
    TPS65987/88 SPI Less Host Programming over I2C (www.ti.com/.../slva972) and
    TPS65987/88 SPI Flash Firmware Update over I2C (www.ti.com/.../slvae21)

    The first describes how an EC can send a patch using PTC commands when no SPI flash is present and the second uses FLxx commands to program SPI flash.

    Reference for these commands is in "TPS65987DDH and TPS65988DH Host Interface Technical Reference Manual (Rev. B)" (www.ti.com/.../slvubh2).

    TPS65988 is supported with UcmCx. I believe support for UCSI is planned.

    Regards,
    Scott

    Hello Scott,

    customer mention that the USB-PD needs driver supporting if working with UcmCx. Do we have driver supporting if working with UcmCx?

    Hello Peter,

    Could you help me understand the last request? There is a Windows based UCmCx driver. Let me know if you need more information.

    Thanks,
    Scott

    Hello Scott,

    Customer is asking that can they use UCM driver mode in TPS65982 for UCSI supporting?, what is the plan for UCSI supporting so far?

    I learned that TPS65988 is supported with Windows based UCmCx driver. Will  support for UCSI is planned.

    Hello Scott,

    customer is interested for TI PD solution: TPS6598x.

    they would like to know if we can support the UCM driver based on RS6 version.(as RS5 we heard we can support)

    May you pls let us know the support availability and any extra charges if this is new to you.

  • In reply to Peter Chen(ICP_FAE):

    Hi Peter,

    There is no UCSI command support for TPS65982. The TPS65988 gained UCSI command support in version CG and later.

    I believe RS6 UCM is being tested now. We may need to discuss further for release and customer specific requirements.
    Regards,
    Scott
