This week our colleague Moritz Weißbrich is taking part in the MOCAST 2022 Conference in Bremen, Germany. Yesterday, he presented our paper on "A Silicon-Proof Controller System for Flexible Ultra-Low-Power Energy Harvesting Platforms".
In this paper, a heterogeneous controller system and its first-silicon ASIC implementation are presented, where the use of a programmable NanoController next to a general-purpose microcontroller enables more efficient and flexible power management strategies than typical timer-based, periodical power-up of a single microcontroller in state-of-the-art IoT devices. The first-silicon ASIC implementation of such a controller system using a 65nm UMC low-leakage process is presented and evaluated for a real home automation application intended to operate on harvested energy, i.e., electronic door lock, reducing the average power consumption of reference microcontrollers by up to 20x.
