CC1310: Power consumption while powered in unprogrammed/factory state

Part Number: CC1310

Team,

my customer uses CC1310 together with an MSP430. They are currently testing the MSP430 functionality only.
Both devices are powered by the same voltage supply, so both devices are powered during tests.

Problem
The CC1310 draws a significant amount of current (approx 6.5mA), even though its functionality is not needed during tests. In fact, the CC1310 is not flashed with any customer software. It is still in factory status.
In general, the CC1310 is only supposed to wake up when needed and instructed to by the MSP430.

Question
Is it possible to set the CC1310 into a deep sleep mode during those tests?

Thanks for your support!

    Hello FRAMziskus,
    How are you measuring current on CC1310? Make sure all the jumpers are off. Please refer to this guide that explains how to measure current www.ti.com/.../swra478c.pdf
    Also it may be helpful to flash the CC1310 with an empty project with just main.c (you can get this from CCS->getting started->new project) and try your experiment.
    Regards,

    Hello Prashanth,

    Thanks for your reply. My customer is measuring with their own custom board, not our EM/LaunchPad.

    What's the expected current consumption when using an empty project? (Idle with 570 μA ?)
    Is there any simple way to set it to standy or shutdown when it is powered on?

    Thanks!

    If this is for the customer I think it is (based on the customer you have had questions for in the past) it would be best to cover this through the support mail since it could require some confidential information to understand this.

    The pinStandby example in the SDK is good to use to measure standby current.

    Thanks TER!
    Different customer. I will see if it makes sense to go through support mail.

    The pinStandby and pinShutdown examples might be a good way.
    The goal is to have the CC1310 in low power mode from start-up in order to not influence current measurement of the rest of the system. There is no switch to switch off power supply to CC1310 separately.

    Regards!
