task_sleep consumption 90µA with CC1310 and tida 0484 based program

Other Parts Discussed in Thread: CC1310, HDC1000, TIDA-00484

on our cc1310 + hdc1000 custom board ( copy of tida_00484 without nanotimer and no external LFosc ) we have a consumption 60 to 90 µA in the sleep mode ( the sleep loop is engaged with task_sleep )

any idea of a solution to enter real sleep ?

thank you

Bernard,

Since your power number is less than IDLE mode (570uA from Table 6-2 from CC1310 datasheet), it looks like CC1310 is properly going into STANDBY mode. I would recommend to check TIDA-00484_Board.c and make sure that you did not configure any internal pullup/pulldown. Based on Section 5.10.11, enabling any internal pulls will cause a slight increase in current consumption.
