International, Berkeley, CA The vision of the Internet of Things with ambient intelligence calls for the deployment of up to a trillion connected wireless sensor nodes (WSNs). Minimizing the carbon footprint of each node is paramount from the sustainability perspective. In ultra-low-power applications, the life-cycle carbon footprint results from a complex balance between both embodied and use-phase energies [1]. The embodied energy arises mainly from CMOS chip manufacturing, and is essentially proportional to die area. Use-phase energy depends on both active and sleep-mode power, because of long stand-by periods in WSNs. In this paper, we present an ultra-low-power 25MHz microcontroller SoC that fully exploits the versatility of a 65nm CMOS process with a low-power/general-purpose (LP/GP)
