CC2651R3SIPA: Power Down Mode

Kumaravel N

Part Number: CC2651R3SIPA
Other Parts Discussed in Thread: Z-STACK

Tool/software:

I have been working with CC2651R3SIPA IC for my project. It acts as a receiver in my project i.e., It receives the data through wireless transmission. I want to make the IC to work in power down mode like when it receives the data it should wake up and do the task and should return to the power down  mode (Standby Mode). Is there any reference example for this case or any idea how I can do it?

Note: IC receives the data only through RF transmission

    Hi Kumaravel,

    As with sleepy end devices in TI's radio stacks, for example 15.4-Stack and Z-Stack, the end device will first send a packet to the always-on controller device to let it know that the end device's receive window is open.  The controller can then send data packets to the end device within that time frame or allow the receive window to expire and let that end device return to standby mode.  I recommend that you implement a similar design for what I assume is your Proprietary RF solution.

    Regards,
    Ryan

    Hi Ryan Brown1,

    Thanks for your reply. Is there any suitable example for this case. If yes, please share.

    rfWakeOnRadioRx: PropRF duty-cycling the radio and entering RX just as much as necessary to detect a packet 
    rfSynchronizedPacketRx: PropRF time-synchronization enables both communication partners to transfer data quickly at predictable time points 
    sensor: TI 15.4-Stack low-power sleepy node
    zed_sw: Z-Stack low-power sleepy end device

    Hi,

    These examples have periodical transmission but our project the packet receiving is a random event and we cannot determine when will the packet is transmitted to the cc2651R3SIPA. Any suggestions what can we do in this case?

     Thank you

    Random receptions require the radio to be active, thus it would not be operating in standby low-power mode.  There needs to be an understanding between the time of the incoming packet for both the receiver and transmitter.  I do not have further suggestions at the moment.
