CC2640R2F: Sleep power consumption BLE5.0 vs 4.2 stacks

Part Number: CC2640R2F


Hi,

I have developed a product which runs on BLE5 stack in CC2640R2F. I have achieved a very small sleep current with all radios and peripherals OFF in this design. This is critical as this device runs from a coin cell and is in sleep state most of the time. Now I have to port this design to BLE4.2 stack.  I know with radio ON, the BLE4.2 stack will consume more. But can I achieve the same sleep current with radio and peripherals OFF?
