   6) What else?

Q2) What does customer have to take care from system test point of view when replacing TCAN1043G-Q1 to TCAN1043A-Q1?

Q3) Are CMCs used with TCAN1043G-Q1 also reusable for TCAN1043A-Q1?

best regards,

    I will send you a link to a comparison document for these devices that will answer most of these.

    The main considerations will be to ensure that the mode behavior for TCAN1043A are accommodated for, such as the mode transition requirements in the case of undervoltage or SWE timer timeout. See the document for a full list of behavioral differences.

    Yes, no change in CMC is required.
