4 CONCLUSION
An MCU-based back-end for duty-cycled wake-up re-
ceivers is introduced. It operates as a DBB with ad-
dressing capabilities and also controls the activity of
WuRx peripherals to reduce the overall energy con-
sumption. The MCU is fully configurable either by
an external unit or by acting on its firmware. Main
configuration parameters including latency, data rate
and ID length allow a wide range of input values. A
prototype is realized as to evaluate the the intended
features. For a latency of T
S
= 32 ms, the DBB con-
sumes less than 1 µW. The power consumption de-
pends on timing parameters, which can be configured
depending on the application requirements. Addition-
ally, several MAC protocols can be implemented to
improve different performance measures, including
energy consumption, overhearing issues and latency.
