SleepRunner microcontroller runs when other sleep

Last week at the IEEE ISSCC conference (#1 in electronic circuits and systems), ECS group from UCLouvain demonstrated their SleepRunner microcontroller (MCU). This MCU was designed to fight obsolescence in IoT by preventing the replacement of batteries and smart sensor devices over a 10+ year lifetime thanks to 1) ultra-low-power energy-harvesting operation and 2) enablement of over-the-air firmware update. Seven years after their previous MCU generation codenamed SleepWalker, the new generation allows to run at 5× more instructions per second (60 DMIPS) within 150µW of active power. SleepRunner thus runs while dissipating the sleep-mode power budget of high-end MCUs.
