Duty Cycling and Autonomous Peripherals

Eterna’s ability to quickly and efficiently transition between Doze and Active states, in conjunction with the ability of

peripherals to operate autonomously for most operations (shown in Figure 9), enables the system solution to significantly

reduce power consumption. For example the system can automatically go from Doze to Active and determine if RF energy is

present. The CPU is then only woken if a packet is detected, otherwise Eterna returns to Doze mode.
