CC2642R: Current consumption

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:

1. 900uA while Sensor Controller is in Active mode
2. 30uA while Sensor Control is in Standby mode

Thanks,
Toby

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:

1. Use BATMON in Sensor Controller every 500msec.
2. Application sleeps forever.

(It is for CC2652R7, but same could be easily ported to CC2652R1, and I expect similar current consumption).
