However, some applications impose additional constraints. For battery-powered sensor nodes deployed in remote locations, the MCU may lie dormant for long periods, only waking up when a sensor detects activity. For such cases, the MCU needs very low sleep power to maximize battery lifetime, deterministic real-time response to capture rare sensor events, and energy-efficient operation with enough compute and memory to run useful workloads. This work shows a 65nm Arm Cortex-M33 SoC for constrained battery-powered sensor nodes achieving 10nW sleep power (4KB retention) with fine-grained DVFS and performance regulation from 0.8MHz (0.40V) to 38MHz
