CC1310: Power calculator

Part Number: CC1310

Team,

we have our BLE power calculator tool on ti.com: link

Is there anything similar for CC1310 with Sub1GHz?

Thanks!

    For sub 1 GHz it's a lot of different parameters and tradeoffs so I'm not sure how easy it would be to make a generic calculator.

    For which setting do you want to calculate power consumption?

    Thanks TER,
    my customer is open to any suggestions what to use.

    How can I estimate power consumption for the modes used in SmartRF Studio, such as 200kbps, 2-GFSK at different output power levels?

    txPower Output power 3V Power consumption 3.0 V Output power 3.8V Power consumption 3.8 V
    3F 12.6 20.8 12.6 17.0
    D5 10.3 16.1 10.4 13.3
    D4 10.2 15.9 10.2 13.1
    D3 10.0 15.7 10.1 12.9
    D2 9.8 15.5 9.9 12.7
    D1 9.6 15.2 9.7 12.5
    41 -1.4 7.9 -1.4 6.5
    C0 -11.0 5.9 -11.0 4.9

    The table above shows the average current @25 degrees in TX. This is mainly the current in the RX core with the CM3 turned off. 

    The current consumption is not dependent on the datarate when in TX but using higher datarate means that a packet can be sent faster and that the time in TX can be shorter lowering the average current. Datarate will also depend on the range required. The range goes up if the datarate is lowered. 

    For the usecase you outlined I would assume that the RX power consumption is more important and if it's possible to time sync the TX and RX side the the RX time can be minimized.
