Part Number: CC2340R5

Dear expert,

Does CC2340R5 have any power sequence requirment? 

I saw that there is only VDDS power needed from external. 

Best Regards,

Eric Chen

    Hi Eric,

    As mentioned in section 1.12 of the CC2340R5 TRM, the system controls the power sequencing of the device, so no need to design external mechanisms.

    Naturally, this requires the VDDR and DCDC pins to be properly connected as shown in either our reference design or in section 6.3.1 of the TRM.

    Hope this helps,

    Rafael
