Hi team,

1.vpp is related to OTP programming, is any requirement when customer program OTP?

2. Is SOP mean boot configuration pin? do we have time requirement for the boot configration pin?

    Hi Shuqing,

    No, BOOT-REQ-002 and PWR-REQ-004 are not required for this device. I will work with the team to provide a guideline column for which F28x devices are applicable for which CSR Requirements.

    Best Regards,

    Hi Fleenor,

    Do you have the new schematic checklist for F2800157, any sequence requirement between SOP and power supply?

    Hi Shuqing,

    Just a reminder that the datasheet is the ultimate golden source for these guidelines and requirements. The Power Sequence requirements for F2800157x can be found here.

    The requirements differ whether you are utilizing the internal VREG or not.

    It may be a few weeks before we have some bandwidth to rehash the schematic checklist.

    Best Regards,
