CC2640R2F: CC2640R2 Current consumption in standby mode

Hello,

  What it is not clear to me, is which board are you using? Could you please clarify this?

Something that we can try is to start with a baseline, could you please comment out the following code in main.c

  /* Initialize ICall module */
//  ICall_init();

  /* Start tasks of external images - Priority 5 */
//  ICall_createRemoteTasks();

  /* Kick off profile - Priority 3 */
//  GAPRole_createTask();

//  SimplePeripheral_createTask();

This should put the device in stand by mode and this should give us the power consumption without any tasks running on the system.

  Thanks,

   David

Hi Alberto,

    Do exactly this below. Use the latest SDK 2.20

1. Import Simple Peripheral Stack Library Project to CCS.

2. Set Predefined Symbol "Display_DISABLE_ALL"

3. At SimplePeripheral_init() call Board_shutDownExtFlash();

4. Disable Advertisement at SimplePeripheral_init() by uint8_t initialAdvertEnable = FALSE; . Rebuild All and flash the hex file to CC2640R2F.

5. Set your Digital Multimeter to measure average uA current. You should be able to read average current of 1.1 uA which is the Standby Current as per datasheet.

Hi All,

thanks for the support,

with the reported advices we got the expected current consumption (3 uA) using the ev board.

Porting the same project on our design we are unfortunately NOT experiencing the same results having a consumption still around 65 uA.

The Main differences in our design (compared to the ev board) are:

1) we use 5x5 mm case instead the 7x7 mm used in the EV board

2) we use CACHE AS RAM enabled

3) the micro is powered directly using a 1V9 without the internal DCDC converter.

May anyone of this differences be the cause of  a higher current consumption? If yes what could be the impact on the consumption in particular for point 3)?

best regards

Alberto
