Hello expert,
Our customer wants to know the current consumption data of CC2642R when using "Temperature Sensor" / "Battery Monitor" function respectively on the Sensor Controller.
Can you please estimate it?
Regards,
A.Fujinaka
Hello A.Fujinaka,
Please see this related post: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1299913/cc1312r-how-to-measure-the-sensor-controller-power-consumption-of-the-cc1312
Estimate is:
Thanks,

Hello Toby,
Their question is the current estimation for these 2 condition.
1. "Temperature Sensor" in Sensor controller active
2. "Battery Monitor" in Sensor controller active
Please answer the current consumption with Sensor controller active CPU 2MHz case.
Regards,
A.Fujinaka
Hello A.Fujinaka,
Both of these, "Temperature Sensor" and "Battery Monitor", are part of BATMON module, so just need current consumption of BATMON.
How often are they reading these values?
Code snippets for reading BATMON temp/battery is located here: https://software-dl.ti.com/lprf/sensor_controller_studio/docs/cc13x2_cc26x2_help/html/aon_domain_functionality__1.html?highlight=aon
Then this guide can be used to integrate it to SDK example, "empty": https://dev.ti.com/tirex/explore/node?node=A__AUC-XrZ8GGESU4pZ9CzTRQ__com.ti.SIMPLELINK_ACADEMY_CC13XX_CC26XX_SDK__AfkT0vQ__LATEST
Next the current consumption can be measured in Energy Trace: https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_7_41_00_17/docs/ble5stack/ble_user_guide/html/energy-trace/energy-trace.html?highlight=energytrace#energytrace-user-guide
I can try to evaluate this and update you within 5 business days.
In the meantime, perhaps you can try out the steps above.
Thanks,
Toby
It is about 1.4uA, with these configurations:
Reference Sensor Controller Studio project and CCS project.
BatMonTempSense.scp scs_battemp_LP_CC2652R7_tirtos7_ticlang.zip
(It is for CC2652R7, but same could be easily ported to CC2652R1, and I expect similar current consumption).
