5 µA
● The turn-off current means the current consumed when
5 µA
CPU, RAM, Clock and some registers remain operating
5 µA while SoC is at very low power consumption status.
●
6 µA
consumed when the power supply source of the whole
6 µA
module is at no-load status.

3.6 V DC
● Although the communication level can be switched with
various methods, the power consumption of the whole
3.6 V DC
module will be affected at great degree.
3.6 V DC
● Modules are compatible with some of the microcontrollers
at 5V communication level. They are too many to be listed
3.6 V DC
here. Please base on practical test or talk to us for more
3.6 V DC
information.
