AM62A7-Q1: Inputs WKUP_I2C0_SCL/SDA

Part Number: AM62A7-Q1

Tool/software:

Hello TI team,

TI's recommendation is to pull-up the balls D13 and E13 (WKUP_I2C0_SCL/SDA) through seperate resistor. Please see attached picture.

On the EVK the ball E13 is unconnected (without pull-up). Is this an error in the circuit diagram or is your recommendation not so strict?

Regards,

Dusan

    Hello Dusan, 

    Thank you for the query.

    Please note that we do not consider our hardware platforms to be a reference design. They are evaluation platforms and may not represent a proper system implementation.
    Our EVM design sometimes out paces our ability to fully understand device requirements. This is done so the hardware platform is available when first silicon arrives. We may learn new device requirements during processor bring-up and bench validation. If so, these new requirements may not be accounted for in our hardware development platform. Therefore, TI expects customers to carefully review and follow all requirements defined in the datasheet, silicon errata, and TRM when designing their system. Our hardware development platforms were not designed to be comprehensive of specific system requirements.

    WKUP_I2C0_SCL/SDA

    A pullup is recommended irrespective of the IO configuration or IO usage.
