Low power BLE Mesh device using TLSR8258F512ET48

Bose

Hai,
  We are planning to develop a BLE mesh node device using TLSR8258F512ET48.
I have small doubt on the power supply and current consumption. In data sheet i found range from 1.8V to 3.8 and typical 3.3v.
Can i power using 3V coin cell battery? we are planning to use CR2032 battery(220mAH capacity).
How long battery will be last?

Best Regards
Bose

The average current of a mesh low-power node with a 2-second poll interval is 50uA(TLSR8258). With an average current of 50uA, the maximum working duration for a 220mAh battery is 180 days.
（mesh LPN节点(TLSR8258)在2秒poll间隔下的平均电流为50uA，220mAH电池理论最长工作180天）。 但不建议用纽扣电池做mesh，纽扣电池在电量不足时电压飘动太大，对flash不友好

纽扣电池需要注意的是在低电量情况下，电压会拉得比较低，电压飘动大。在flash工作电压范围外操作flash，flash内容容易异常。 需要硬件保持电压稳定，比如加大电容等。
